Asphalt mixing plant work required aggregate

Aggregate have coarse and fine, it is the largest proportion in the asphalt mixture, its quality on the asphalt mixture quality, construction, road performance have an important impact. Aggregate strength, wear value, crush value, ruggedness and particle size gradation must meet the relevant requirements of the Technical Specifications. Storage field should use appropriate materials hardening, puzzle on the wall, do a good job in the station drainage. In the case of good equipment running conditions, aggregate specifications, water content, impurity content, supply and so on is an important factor affecting the production of leaching station. Sometimes the aggregate contains large stones, may cause the mouth to block, scratch the belt and so on. Welding screen and sent to the basic management can be resolved. Some aggregate size does not meet the specifications, in a certain amount of waste in the aggregate to increase the waiting time to wait, more material, the material out of the material greatly extended, which not only cause energy waste, but also severely constrain production, Affect production efficiency. Aggregate rain after the water content is too high, resulting in blocking hopper, drying uneven, stick in the heating drum wall, the temperature is not easy to control, out of white and other quality problems. As the production of stone in the community is not planned, road and building materials specifications are not the same, often stone processing specifications and specifications do not match, often appear in short supply phenomenon. Some specifications aggregate in the new river has been interrupted at high speed, it should grasp the material specifications and material requirements, ahead of preparation.
