QLBY Series Mobile Asphalt Mixing Plant

1. The combined structure of drum dryer and batcher is mounted onto the movable support, which facilitates their movement.
2. The asphalt mixing plant comes with twin horizontal shafts that are able to bring the aggregates to a fierce boil, which ensures a thorough mixing.
3. Hot aggregate is vertically lifted up in the densely arranged hanging buckets. This kind of lifting tool is easy, reliable to use.
4. For accurate weighing of aggregates, bitumen, and pulverized mineral, the measurement scale is used, which contains a weight sensor for electronic metering.
5. The movement of power material follows an enclosed, spiral path which guarantees minimum material loss as well as provides safety transfer. 

Main Components of The Series Mobile Asphalt Mixing Plant

1. Cold Feeder 

The automatic batching station comes with three or four hoppers. Aggregates contained in the hoppers can be weighed together by using one scale. Loader is used to supply aggregates to the hopper. Via the programmable logic control system, the weighed aggregates are inspected and automatically compensated to ensure an accurate feed with minimum error rate. Belt conveyor is fitted with scraper and tracking adjustment roller.

Note: Mobile cold feeder is also available upon customer's request.

2. Main Plant

1) The drying drum of the asphalt mixing plant is constructed of Q345 high-strength alloy steel, which is able to withstand washing and high temperatures without deformation. It is designed with optimized structure. Its manufacturing process is nationally distinct.
2) Unique vane arrangements enable the material to move about violently in the direction parallel to the axis, which in turn ensures an even heating over the feedstock and improved quality of the end product.
3)At the joints between two moving parts, there are labyrinth seals to ensure a dust-tight, secure seal.

4)Dual horizontal axis setups of the forced mixer overcome the problem faced by single axis arrangement. That is to say, the former can eliminate dead areas where materials accumulate out of the reach of mixing paddles. Its finished product has consistent good quality. During mixing, the two horizontal axes will bring the material to a fierce boil so as to ensure it gets thoroughly and rapidly mixed. The liner, mixing arm, and mixing paddle are cast from wear-proof, high strength alloy steel, featuring a long serving life.

3. Hot Storing Bin

The finished product silo of our asphalt mixing plant is lifted up by a winch via the steel wire cable. The winch is also fitted with a brake gear.
The large-diameter cylinder will open to dump the material. The load capacity of the silo can be 2.5 ton, 5 ton, or 9 ton. The lifting bucket adopts the traverse limit switch and PLC time control, which enables a stable, reliable operation.
