Equipped with an automated computer control system, it can minimize unnecessary human errors while reducing operators’ labor time, effectively improving production efficiency. In addition, high-precision asphalt mixing equipment enables manufacturers to complete asphalt mixing and production with less raw materials and fuel, realizing energy and cost savings. At the same time, it can effectively control product quality, further enhancing the performance and qualification rate of finished asphalt mixtures. The working process of asphalt mixing equipment is an integrated operation that includes three core links: aggregate conveying, mineral powder conveying and asphalt conveying, each with strict procedural norms. For aggregate conveying, a cold aggregate supply system stores various raw materials. Gravel is first conveyed to the drying system via an inclined continuous feeding belt conveyor, then transported to the screening system by a hot aggregate bucket elevator after drying and heating. In the vibrating screen, aggregates of different particle sizes are sorted into corresponding hot aggregate hoppers, conveyed to the aggregate weighing device, and fed into the mixing drum after accurate weighing. For mineral powder conveying, dust generated during aggregate drying is collected by the dust collection system and delivered to the powder recovery silo. Fresh mineral powder is transported to the mineral powder silo, blended uniformly, weighed, and then discharged into the mixing drum. Asphalt conveying involves pumping asphalt into thermal insulation and heating storage tanks, then conveying it to the asphalt weighing device. The weighed asphalt of specified quantity is discharged into the mixing drum. After the three conveying processes, all materials are uniformly mixed in the mixing drum for a specified time. Finally, the asphalt mixture is discharged into the finished product hopper and transported to construction sites by heated asphalt transport trucks. This whole process ensures efficient, stable and high-quality asphalt mixture production, providing solid support for various infrastructure projects.

Asphalt mixing plants are indispensable industrial equipment at construction sites, mainly used to produce asphalt and concrete for infrastructure projects such as highways, graded roads, municipal roads, airports and ports.

These problems mainly stem from high-temperature friction between the drying drum and supporting rollers/wheel rails after prolonged operation, combined with severe equipment vibration during material drying. The vibration directly leads to improperly adjusted clearances between wheel rails and supporting rollers, or misalignment of their relative positions. To avoid such faults, operators must apply lubricating grease to the contact surfaces of supporting rollers and wheel rails after daily operation. Meanwhile, they should promptly adjust the tightness of fixing nuts and effectively regulate the clearances between components to ensure stable operation and even force distribution at all contact points, preventing operational obstructions. The dismantling of asphalt mixing plants is a large-scale and complex project that requires strict compliance with standardized procedures. Prior to dismantling, a feasible plan must be formulated based on the plant’s location and actual conditions. All dismantling and installation personnel must receive comprehensive technical and safety briefings to ensure operational safety. Before dismantling, it is necessary to complete the inspection, registration and filing of the plant’s accessories and external condition. During the initial installation, a relative position drawing of the plant should be made to provide a reference for subsequent assembly work. It is strictly prohibited to cut any cables or wires during dismantling. Dismantling can only be carried out after verifying the accuracy of all internal and external wire numbers and terminal board numbers. If any discrepancy is found, the wire number labels must be adjusted accordingly. Strict adherence to these operation, maintenance and dismantling norms is crucial for ensuring the safe, stable and efficient operation of asphalt mixing plants, extending their service life, and maintaining core competitiveness in the fierce market.

The construction of asphalt mixing plants must strictly comply with specified regulations, which is not only a guarantee for construction quality but also crucial to preventing damage to asphalt mixing equipment. While focusing on key engineering details, proficient mastery and application of essential construction methods are also indispensable for the smooth progress of the project. Standardized construction ensures the stable operation of subsequent equipment and lays a solid foundation for efficient asphalt mixture production. Prior to construction, thorough site preparation is required. It is necessary to completely remove collapsible loess on the top of the foundation wall and keep the construction site dry. The finished elevation of the graded site must meet the requirements of the design plan. If the soil layer is too soft, appropriate subgrade reinforcement measures should be taken to prevent equipment imbalance during construction and ensure the verticality of the pile frame, which is a key prerequisite for subsequent construction safety. All construction machinery delivered to the site must undergo strict inspection to ensure they are in good working condition. Assembly and commissioning can only be carried out after confirming that the machinery complies with relevant specifications. During installation, the levelness of the asphalt mixing plant must be guaranteed; the deviation of the guiding performance and the mixing shaft relative to the pavement flatness shall not exceed 1.0% to avoid affecting the operation accuracy of the equipment. Setting-out work must be conducted in strict accordance with the pile position layout plan, with the allowable deviation not exceeding 2 cm. For the installation of asphalt mixing equipment, a Φ25mm water tap is adopted, and a 110KVA construction power supply is configured. This ensures the normal and stable operation of the power supply system and all material conveying systems, providing reliable support for continuous construction. After the accurate positioning of the asphalt mixing plant, the motor can be started. The wet spraying method shall be used for pre-mixing and soil cutting to make the equipment sink smoothly. Drilling and soil cutting can only start at a lifting speed of 0.45~0.8 meters per minute after the mixing shaft has sunk to the depth specified in the design plan. Strict adherence to this construction procedure ensures construction safety and quality. The company is committed to providing high-quality asphalt mixing-related equipment, including asphalt mixing equipment, asphalt mixers, asphalt mixing plants, asphalt mixture mixing equipment and thermal oil-heated asphalt equipment. Adhering to standardized construction and matching high-quality equipment is the key to promoting the efficient and safe development of road construction projects.

Asphalt has been increasingly adopted as a core raw material in fields like construction and urban road engineering due to its excellent reliability. Manufacturers carry out customized asphalt production based on customer demands and utilize professional technical equipment for asphalt mixing. The new-generation asphalt mixing equipment, compared with traditional models, boasts more advanced technology and higher operational efficiency, equipped with an automated computer control system that minimizes human errors and reduces operators’ workload. High-precision asphalt mixing equipment is widely used in production, enabling more efficient utilization of raw and natural materials. It also achieves precise control of product quality, effectively improving the performance of finished asphalt mixtures. These application benefits make the equipment an indispensable core component in asphalt production and road construction projects. The full operational process of asphalt mixing equipment integrates three key links: aggregate conveying, mineral powder conveying and asphalt conveying, with strict procedural norms to ensure stable production. For aggregate conveying, a cold aggregate supply system stores various raw aggregates. Gravel is first conveyed to the drying system via an inclined continuous feeding belt conveyor, then transported to the screening system by a hot aggregate bucket elevator after drying and heating. In the vibrating screen, aggregates of different particle sizes are sorted into respective hot aggregate hoppers, conveyed to the aggregate weighing device, and fed into the mixing drum after accurate weighing. For mineral powder conveying, dust generated during aggregate drying is collected by the dust collection system and delivered to the collection silo. Fresh mineral powder is transported to the mineral powder silo, blended uniformly, weighed, and then discharged into the mixing drum. Asphalt conveying involves pumping asphalt into thermal insulation and heating storage tanks, then conveying it to the asphalt weighing device. The weighed asphalt of specified quantity is discharged into the mixing drum. After completing the three conveying processes, all materials are uniformly mixed in the mixing drum for a specified duration. Finally, the asphalt mixture is discharged into the finished product storage silo and transported to construction sites by heated asphalt transport trucks. This whole process ensures efficient and high-quality asphalt mixture production, providing solid support for road construction.

In road construction machinery, asphalt mixture mixing equipment and asphalt mixing equipment are essentially the same type of machinery, with no substantive distinction between them—only differences in nomenclature. Similarly, asphalt mixture mixing equipment and asphalt concrete mixing equipment also belong to the same category of machinery and equipment, and the two names are interchangeable without any essential differences. In terms of actual product types, asphalt mixture mixers are mainly classified into three categories: compulsory type, single horizontal shaft type and double horizontal shaft type, which are widely used in various road construction projects according to different construction needs. In the actual operation process of asphalt mixture mixers, many users often encounter some common problems, among which the abnormal noise generated by the mixing bowl during operation is a typical one.

Timely inspection and replacement of damaged mixing arms and jaw plates are crucial to ensure the normal and stable operation of the equipment. As environmental protection requirements in the construction industry become increasingly stringent, dust removal devices have become an indispensable part of asphalt mixture mixing equipment. In terms of dust removal methods, dry dust removal is the primary choice for asphalt mixture mixing equipment because its raw materials are easy to obtain and the use cost is relatively reasonable. At present, there are three types of dust removal equipment commonly used in the market. Filter dust collectors, as a common type of dry dust removal equipment, can effectively capture and filter dust particles generated during the operation of the mixing equipment through filter elements, with high dust removal efficiency. Centrifugal fan dust collectors rely on the centrifugal force generated by the high-speed rotation of the fan to separate dust from the air, which is suitable for scenarios with large air volume and medium dust concentration. Force dust collectors, on the other hand, use mechanical force to separate dust, which has the advantages of simple structure and convenient maintenance. All three types of dust removal equipment can be effectively applied to asphalt mixture mixing equipment, helping enterprises meet environmental protection emission standards. In summary, clarifying the terminology definition of asphalt mixture mixing equipment, mastering the causes and solutions of common operational problems, and selecting appropriate dust removal devices are of great significance for improving the operational efficiency of the equipment, ensuring construction safety and complying with environmental protection requirements. For road construction enterprises and equipment operators, a comprehensive understanding of these key information can help them better use asphalt mixture mixing equipment and provide strong support for the smooth progress of road construction projects.

The asphalt mixing equipment referred to herein usually also means asphalt concrete mixing plants.

In addition to precise ratio control, it is also necessary to determine the appropriate mixing method and duration to ensure that the asphalt mixture meets the on-site construction conditions and technical standards. Integrated asphalt mixing plants can accurately control all links of the mixing process through standardized design and intelligent control, thereby effectively ensuring the stability and reliability of product quality. Feasible sampling inspection is also an important advantage brought by the use of integrated asphalt mixing equipment. After the asphalt mixture is produced in the mixing plant, quality inspectors can conduct targeted sampling inspections on the finished products in a timely manner. This sampling inspection link can directly verify whether the finished asphalt mixture meets the pre-set application requirements and relevant national standards, and timely discover and rectify potential quality problems. The convenience of sampling inspection provided by integrated equipment further builds a "double guarantee" for product quality. In summary, the widespread adoption of complete sets of integrated equipment for asphalt mixing is mainly to ensure that the final asphalt mixture can fully meet the actual needs of production and construction. Integrated mixing plants can achieve precise control of mixing duration and material feeding sequence, laying a solid foundation for meeting various application requirements. At the same time, the use of integrated equipment facilitates effective sampling inspections, further ensuring that product quality complies with construction specifications. For the infrastructure construction industry, the promotion and application of integrated asphalt mixing equipment are of great significance for improving construction quality and efficiency.

Asphalt mixing plants have become indispensable equipment in construction sites and various engineering projects across China, with a wide range of applications and making significant contributions to the country’s infrastructure development.

For any asphalt mixing equipment to achieve the expected operational effect and play its due role in construction projects, it must comply with these inherent criteria. Only equipment that meets quality standards and is user-friendly (with stable performance and simplified operations) can effectively ensure operational efficiency, control production costs, and guarantee the quality of asphalt concrete products. In summary, asphalt mixing equipment, as an indispensable key equipment in infrastructure construction, undertakes the important task of providing high-quality asphalt concrete for various key projects. Strictly abiding by the operational requirements of excellent stability and simplified procedures is crucial for the equipment to exert its maximum value. This not only helps to improve the efficiency and quality of road construction but also provides solid support for the healthy and sustainable development of the transportation infrastructure construction industry.

With the launch of national dual-carbon goals, supporting the achievement of carbon peaking and carbon neutrality has become an indispensable historical mission for the concrete industry. "Green, environmental protection and intelligence" has emerged as the core development direction for enterprises in the new era. In response, local governments have successively issued regulatory documents on green production of concrete enterprises, setting time limits for environmental transformation of existing batching plants and establishing environmental access thresholds for new ones, driving the industry into a new stage of green and sustainable development. The concepts of "green low-carbon", "energy conservation and emission reduction" and "sustainable development" have become the core guidelines for transforming traditional batching plants and building new eco-friendly ones. To meet increasingly stringent environmental requirements and change the stereotype of excessive dust and uncontrolled wastewater discharge, concrete batching plants need to focus on key transformation aspects. The intelligent feeding system is a key upgrade: traditional production lines require two loaders and four shifted drivers, while the fully automatic system allows trucks to unload directly into the hopper, with belt conveyors and distributors automatically transporting materials to silos and completing batching. This saves labor and equipment costs, eliminates loader-related fuel consumption and noise, and avoids batching dust pollution. Dust control is critical for environmental compliance. Replacing loaders with belt conveyors for large stockyard feeding effectively reduces noise and dust. High-performance pulse dust removal systems are installed at key production points such as belt conveyor connections and main building transition hoppers. Fully enclosed stockyards, equipped with atomizing spray systems, isolate dust and adsorb suspended particles via high-pressure atomized water, minimizing dust diffusion to the maximum extent. Other key transformations include the twin-screw mixing host, which uses continuous spiral blades to enhance material circulation and shearing, improving concrete homogeneity and production efficiency to boost plant profitability. Wet concrete recycling equipment achieves "zero discharge" by decomposing and reusing daily waste residue and wastewater, recycling sand, gravel and slurry for production to save resources. Additionally, the intelligent commercial concrete control system promotes the industry’s shift from traditional production to intelligence and informatization, which is an inevitable path for industrial upgrading, cost reduction and efficiency improvement. Under the dual-carbon strategy, accelerating green and intelligent transformation not only helps concrete batching plants meet environmental regulations but also enhances core competitiveness, laying a solid foundation for sustainable industry development.

A concrete batching plant is a professional integrated mechanical equipment unit dedicated to the production and processing of concrete, playing a pivotal role in construction projects such as buildings, roads, bridges and water conservancy. The quality of finished concrete is directly linked to the safety and durability of construction projects, and scientific raw material management is the core guarantee for stable concrete quality. The production raw materials of concrete batching plants cover basic materials including cement, sand, gravel and fly ash, as well as functional additives like retarders, water reducers, release agents and antifreeze agents. Strict management norms must be followed for different types of raw materials during production to avoid quality risks. Sand and gravel management is a fundamental part of raw material control. Different specifications of sand and gravel must be stored in separate silos with clear labels, indicating raw material name, type, specification, place of origin and purchase date. The warehouse keeper shall assign a unified serial number to each silo, draw a stockyard zoning map, and notify the laboratory, central control room and loader operators in a timely manner. It is also necessary to cooperate with relevant personnel to confirm the silo number corresponding to each batching scale and record all storage information in detail, so as to ensure the accuracy of sand and gravel feeding and avoid mixing of different specifications. The management of powder materials such as cement, fly ash and superfine powder is more stringent. Each powder silo shall be assigned a unique serial number and labeled with raw material name, place of origin, type and specification. The feed inlet shall be marked with consistent information including purchase date and stock quantity, and be locked and managed by designated personnel. When powder materials are delivered, receiving personnel and suppliers must jointly inspect and sign for confirmation before opening the silo for feeding. This strict process can effectively prevent feeding errors and avoid concrete quality accidents caused by wrong materials. Admixture management also needs standardized operation to ensure that concrete performance meets project requirements. Bulk bagged powder admixtures shall be stacked neatly in a special warehouse with signboards clearly indicating name, type, specification, place of origin and purchase date. Liquid admixtures must be stored separately according to different manufacturers and types, with distinct identification marks to prevent mixing. Reasonable storage and clear identification of admixtures can avoid confusion during use and ensure that the dosage and type of admixtures are accurate, thus guaranteeing the workability, strength and durability of concrete. In summary, standardized management of sand, gravel, powder materials and admixtures is crucial for concrete batching plants. Strict implementation of classification storage, clear labeling, standardized operation and detailed recording can effectively avoid raw material confusion and feeding errors, ensure the stability and high quality of concrete products, and provide solid support for the smooth progress of various construction projects. Scientific raw material management is not only the basic requirement of concrete production, but also an important means for batching plant enterprises to enhance core competitiveness.

The vibrating screen of the equipment is driven by an imported vibration motor, which not only significantly improves the screening efficiency of materials but also reduces the equipment failure rate, ensuring long-term stable operation of the production line. In terms of energy conservation, environmental protection and space optimization, the mobile type also has obvious advantages. The bag dust removal device is placed in a dry state above the drum, which can effectively reduce heat loss, save valuable site space and reduce fuel consumption, achieving the effect of energy conservation and emission reduction. The optimized silo bottom structure greatly reduces the overall floor space of the equipment. At the same time, it cancels the lifting space of the finished product trolley, simplifies the equipment structure and further reduces the failure rate. In addition, the mobile asphalt mixing plant adopts a dual-machine automatic control computer/manual control system, equipped with an automatic fault diagnosis program. This humanized design makes the operation simpler and safer, allowing operators to quickly grasp the operation skills and timely deal with potential faults. The aggregate hoist adopts double-row plate chain lifting technology, which effectively extends the service life of the hoist and improves the stability of operation. In summary, the asphalt mixing plant, especially the mobile type, with its complete functions, stable performance and flexible application, provides strong support for the high-quality and efficient development of the global infrastructure construction industry.

In recent years, the construction and development of domestic asphalt pavements such as highways and urban roads have been in full swing, which has strongly driven the market demand for asphalt mixing equipment—a core and indispensable equipment for road construction and maintenance. Relevant industry data shows that by the end of 2011, the total length of domestic asphalt pavements had exceeded 570,000 kilometers. During the "Twelfth Five-Year Plan" period, the average annual growth rate of domestic asphalt pavement roads exceeded 9%, and the expressway mileage was expected to reach more than 130,000 kilometers. At present, the construction of asphalt pavement roads is still in a stage of rapid development, which continues to boost the stable growth of demand for asphalt mixing equipment. From the perspective of the current market competition pattern, there are more than 30 asphalt mixer manufacturers in China, but only about 20 enterprises have a certain scale of efficiency. The industry competition presents a hierarchical characteristics. Foreign-funded enterprises in the market have formed a certain monopoly position relying on their strong capital strength and advanced technological advantages, and have a certain dominant power in product pricing, thus maintaining a relatively high profit level. However, with the continuous expansion of Sino-foreign joint ventures and the gradual maturity of domestic customer groups, the market competition faced by foreign-funded enterprises in China has become increasingly fierce. Domestic leading asphalt mixing equipment enterprises have continuously narrowed the gap with foreign brands in product quality through independent technological accumulation and long-term brand cultivation. While their products maintain a relatively high price level, they also have a high profit income and occupy a large market share. In contrast, the low-end segment of the asphalt mixing equipment market has a large number of participating enterprises. Most of these enterprises have problems such as unreliable product quality and low product pricing, making it difficult to form a large-scale income and lack core competitiveness. On the whole, the income and profit levels of China's asphalt mixer industry have maintained a growth trend in recent years, but there are obvious differences in the growth rate between enterprises of different scales. The growth rate of leading enterprises is significantly lower than that of small and medium-sized enterprises. Industry insiders pointed out that in order to maintain strong market competitiveness, domestic asphalt mixer enterprises need to continuously improve their technical level and product quality, attach great importance to brand building, and establish sales channels that are in line with the development trend of the industry. Looking forward to the future development of the industry, China's asphalt mixing equipment will show three major development trends. Firstly, large-scale asphalt mixing equipment will become the mainstream direction to meet the needs of large-scale infrastructure construction. Secondly, energy-saving, emission-reducing and environment-friendly asphalt mixing equipment will be more favored by the market under the background of increasing environmental protection requirements. Finally, the automatic and intelligent control of products will attract more attention from enterprises, which will become an important direction to improve production efficiency and product quality.

The vibrating screen is a key component of asphalt mixers, and its stable operation directly affects the efficiency and quality of asphalt mixture production. A tripping fault occurred in the vibrating screen of an M365 asphalt mixer during no-load operation, and the tripping phenomenon recurred immediately after restarting. This fault seriously interrupted the normal production process, so it is crucial to quickly locate the cause and implement effective troubleshooting. After the fault occurred, the maintenance team first carried out a comprehensive inspection of the electrical system. They replaced the new thermal relay, but the tripping fault still existed. Subsequently, they checked key electrical components and parameters including contactors, motor phase-to-phase resistance, grounding resistance, and phase-to-phase voltage, and no abnormalities were found. To further verify whether the electrical part was faulty, the maintenance personnel removed the transmission belt and started the vibrating screen independently. The ammeter showed a normal value of 10A, and no tripping occurred during 30 minutes of no-load operation. This result confirmed that the fault was not caused by the electrical system, and the problem should lie in the mechanical part of the vibrating screen. After reinstalling the transmission belt and restarting the vibrating screen, the maintenance team observed that the eccentric block of the vibrating screen vibrated more violently than usual, which became an important clue for fault location. To confirm the problem, the maintenance personnel removed the eccentric block and restarted the vibrating screen. At this time, the ammeter reading increased to 15A, which was significantly higher than the normal value, indicating that there was an abnormality in the mechanical transmission part related to the eccentric block. In order to accurately find the root cause of the fault, the maintenance team fixed a magnetic dial indicator on the vibrating screen box and used a stylus to check the radial runout of the shaft end. The measurement results showed that the maximum radial runout of the shaft end reached 3.5mm, which exceeded the normal range. Then, they disassembled the bearing of the vibrating screen for inspection and found that the maximum ellipticity of the inner diameter of the bearing was 0.32mm, which did not meet the technical requirements. The excessive radial runout of the shaft end and the elliptical deformation of the bearing inner diameter led to abnormal mechanical operation, increased load, and thus caused the tripping of the vibrating screen during operation. Based on the above inspection results, the maintenance team replaced the faulty vibrating screen bearing, reinstalled the eccentric block, and restarted the vibrating screen. After the maintenance, the ammeter indicated a normal value of 10A, and the tripping phenomenon no longer occurred. This case shows that for the tripping fault of the asphalt mixer vibrating screen, it is necessary to conduct a systematic inspection from both electrical and mechanical aspects, and accurately locate the fault point through targeted tests. Timely replacement of damaged mechanical components such as bearings can effectively ensure the stable operation of the vibrating screen, and then guarantee the continuous and efficient progress of asphalt mixing production.
