Asphalt hot mix plant consists of cold aggregate system, drying system, dust collecting system, hot aggregate lifting and storage system, mixing tower, finished products storage bin etc, which is mainly used for aggregate- asphalt hot mix for construction of flexible pavement. The paving surface quality is depended on the asphalt binding ability. Our hot mix plant for sale can ensure high asphalt binding ability and even asphalt mixture products. Our asphalt hot mix plant confirms more models for selecting. The largest capacity of our offered products can reach 320t per hour to meet different construction requirements.
According to the production capacity, the hot mix asphalt plant has mini, medium and large types. Capacity of 120t to 320t belongs to large asphalt hot mix plant, 60t to 100t is medium asphalt hot mix plant and under 60t is mini asphalt mix plant.
For the transport mode, there are stationary and mobile types. The mobile hot bitumen mix plant can move with chassis device. It can realize movement during construction. While the stationary is fasten to the construction sites.
In terms of the technical process, asphalt hot mix plant has continuous drum type and batch type. The processes of drum hot mix plant are continuous. The drum type keeps working all the time. The batching type can realize intermittent forced mixing in separate mixer.

Parts of our asphalt hot mix plant
1.Cold aggregate supply units
Our cold aggregate consists of hopper, feeding machine, aggregate conveying belt etc. The feeding machine is equipped with frequency control device. The device can automatically control feeding speed in synchronous proportion, which is convenient, reliable and safe. The filter screen in mounted on the conveying belt to rule out bigger size of cold aggregate, which can reduce unnecessary heat loss in the following production process.
After the cold aggregate enters the dryer drum, the burner will provide heat source to heat the cold aggregate. The moisture of aggregate will dry in high temperature. The outside of drum has insulating layer to keep temperature stable.
Hot aggregate weighing device adopts international well-known Mettle-toledo weigh sensor, which can measure accurately and compensate error automatically. Reasonable weighing order can prevent partial load. Mineral weighing hopper has pressure relief and arch broken devices. The outlet of measuring screw conveyor has a quick pneumatic butterfly valve with small impulse. The insulating layer is set on the asphalt weighing tank. The tank body, spray pump and conveying pipe are insulated with conduction oil. Asphalt can be measured twice times to ensure accurate and stable asphalt-aggregate ratio.
The hoister is used to transport the hot aggregate to the upper of the mixing tower. The hopper can avoid less abrasion with the high strength plate chain hoister. The hoister adopts anti-weary materials to prolong its service life.
The bottom of old and new powder silo has arch broken device, which can prevent powder arching efficiently and ensure uniform and continuous powder supply. Vertical and modularity powder silo can be installed and transported quickly. The outlet of silo has manual valve, which is convenient to maintain.
The asphalt tank and pipes has insulating layer with small heat loss. The asphalt is installed liquid level and temperature display device, which is convenient to operate. The complete automatic control system of conduction oil furnace can be operated independently.
