Asphalt mixing equipment is to connect each relatively independent unit to form a system with the agitator as the center. Stationary asphalt mixing plants parts are similar with other type asphalt plant, mainly consist of the cold aggregate supply system, drying and heating system, combustor, hot aggregate elevator, vibrating screen, measure system, dust collecting system, hot aggregate supply system, mixing system, finished product storage system, control system, etc.
Cold Aggregate Feed System
The singer hopper with large capacity is good to make the material classification for the customers. And the wide load of each hopper makes the feed smooth and efficient. The conveying belt has the frequency control device, which can control the feeding speed. What’s more, the material shortage warning indicator can avoid the hoppers without material.
Dry Drum
In the manufacture of asphalt mixture, moisture must be removed from the cold aggregate to ensure its bonding to the asphalt. In order to attain the optimum heating effect, the dryer drum has insulating layer to prevent heat loss.
Mixer
Mixing system is one of the important parts of asphalt batch mixing plant. This type drum is a combination of a drying drum and a stirring drum. There are mixing blades welded on the inside of the drum, which can produce even mixing materials. The intermittent asphalt plant has a separate mixing bin in the mixing tower. The mixing cycle takes only 45 seconds. The mixing capacity is large, so the mixing machine load is large. Therefore, the fixed asphalt mixture plant is made of high wear resistant material to ensure the durability of the plant.
