The core raw materials of asphalt mixing plant are aggregate, asphalt, mineral powder, and recycled asphalt (RAP) can be added at the same time, of which asphalt is a viscous material that requires special heating and heat preservation for storage, and mineral powder is used to enhance the viscosity and strength of asphalt mixture, and the storage and transportation of raw materials require higher requirements, and the cost is also relatively high.
عملية الإنتاج Dالإفتراءات
Concrete batching plant adopts cold mixing process, no heating of raw materials, just cement, aggregate, water and additives according to the proportion of ingredients, directly into the mixing equipment for mixing, the process is relatively simple, easy to operate, the production cycle is shorter.
Asphalt mixing plant adopts high-temperature heating and mixing process, the aggregate needs to be heated to the specified temperature first, after removing the water, and then mixed with the heated bitumen, mineral powder and other raw materials, the process is more complex, involving heating, grading, mixing and other aspects of the operation of the professionalism of the requirements of a higher.
Differences in Mixing Temperature Requirements
The difference in temperature requirements is the core of the difference between the two production processes.
concrete batching plant adopts room temperature mixing, no additional heating, only in the appropriate ambient temperature for batching and mixing can be, the operation is less difficult, less affected by the ambient temperature (extreme low-temperature environment need to take anti-freezing measures).
Asphalt mixing plant needs to strictly control the mixing temperature, usually requires the aggregate and asphalt heated to 140 ℃ -180 ℃, the accuracy of temperature control directly affects the quality of asphalt mixture, the temperature is too high or too low will lead to the performance of the mixture does not meet the standard, so the need for professional temperature control system.
Main Binding Materials Dالإفتراءات
The difference of core binder material determines the performance and application scenarios.
