The research and development of asphalt mixing plant in Daswell

Besides concrete mixer, in order to meet the requirement for high lever pavement, Daswell produces asphalt mixing plant with LB1000, LB1500, and LB2000 which adopts advanced technologies and scientific researching results from home and abroad. The overall plant are composed by Asphalt mixing body, Drying system, Aggregate conveying system, Hot aggregate hoister system, Stone and filler hoister, Screening system, Weighing system, Bitumen heating system(oil or directly-heated asphalt tank), Bitumen supply system, Bag house dust collector system, Finished storage hopper system, etc. The whole plant adopts Microcomputer Control System. Asphalt mixing body made by high quality armor plate, Burner and Sensor are high qualities in domestic. Auto-control system adopts OMRON Sensor, EVOC Industry Control Computer. The whole structure is reasonable, high automatic, and safe.


Aggregate batching and supplying system is composed by ground aggregate bins and conveying belts. Ground aggregate bins adopt adjustable gate structure. User can adjust the charging size according to the practice demand, which can greatly satisfy with different users’ demand. The conveyor belt from ground aggregate bin is driven by frequency transformation motor, which achieves speed staples adjustment. So that Aggregate batching accuracy can reach + (-) 1%. Under frequency transformation control, charging equipment failure is very low, which can prevent motor damaging and belts fault when it happen stone blocking in normal work .
