Types of Mini Asphalt Mixing Plants for Sale
Our company has launched different types asphalt mixing plants to meet the market requirements, including hot mix mini asphalt mix plant, mini portable asphalt plant, mini asphalt drum mix plant and mini mobile asphalt plant. All of the asphalt plants can blend aggregate, asphalt and filler in designed proportion to produce asphalt mixtures under specified temperature.
The portable asphalt mixing plant and mobile asphalt mixing plant have a common characteristic of easy movement. In addition, the mini feature makes the asphalt mixing plant more convenient.
The mini asphalt drum mix plant is special in the drum. The drum asphalt mix plant integrated the dryer drum and mixing drum together. The unique design reduces the production processes. The simplified mixing process in the drum can reduce the dust pollution. What’s more, the hot aggregate needn’t be lifted, sieved and weighed twice time. The aggregate is just weighed before transported to the dryer drum. The processes of mixing, discharging and filling materials are continuous.
Technological Processes of The Mini Asphalt Batching Plant
1. Cold aggregate supply system
The loader shovels different kinds of sandstone into the cold aggregate hopper. The cone-shaped hopper discharge cold aggregate to the aggregate belt conveyor. Frequency control device is mounted on the outlet of hopper to control the discharge speed. Then the cold aggregate will be delivered to the feeding belt conveyor. The middle filter screen between two belt conveyors can rule out oversized aggregate, which can reduce heat loss in the following process. Finally, the cold aggregate will be conveyed into the dryer drum.
2. Dryer drum
The dryer drum Drying system will fully dry cold aggregate with reverse airflow. With drum rotating, the aggregate in the drum raises and drops with the rolling blades. The formed curtain increase heat interchange. With the help of title drum, the sandstone is constantly moving forward the outlet while heating.
3. Weighing system
After sieved through the vibrating screen, the hot aggregate is conveyed to weighing system. The Mettle-toledo weighing sensor ensures accurate weighing. The asphalt weighing adopts double screw conveyor. The mineral weighing has pressure relief and arch broken devices. The asphalt weighing adopts two-stage anti-overflow protection device. In addition, the asphalt has secondary weighing to ensure accurate and stable asphalt-aggregate ratio. Then they will be delivered to the mixer.
4. Mixing system
The mini drum asphalt mixing plant will finish mixing in the mixer drum in the drying drum mixer. The double drum design makes the drying and mixing in the same device. The inner side of drum has welded with small mixing blades, which can produce asphalt mixture effectively. While the other mini asphalt plant sale has an individual mixing bin in mixer tower. The separate mixing bin can mix the asphalt mixture more evenly. High wear-resistant chromium alloy blades and liners can prolong life span.
