LB asphalt hot mix plant

Concrete machine supplied by DASION Machinery

LB asphalt hot mix plant model has LB500, LB800, LB1000, LB1500, LB2000, LB3000 and LB4000, asphalt mixing plant is composed of cold aggregate supply system, drum dryer, coal burner, coal feeder, dust collector, hot aggregate elevator, vibrating screen, filler supply system, weighing and mixing system, asphalt storage, bitumen supply system.

Introduction of Asphalt Mixing Plant Components:
1.Drying System
The dry drum drive is driven by a four wheel friction drive.
2.Combustion System
Configuration: fuel burner
The use of digital inverter burner, combustible wood, heavy oil and residue, the burner energy saving, adjusting the ratio of 1:10, high temperature control accuracy.
3.Dust Remove & Noise Reduction System
Dust removal system equipped with first class gravity dust collector and secondary cloth bag filter. The equipment from the largest noise 30 meters ≤80dB, Control room noise ≤70dB.
4.The Screening System
Adopts German technology double layer 4 sieve shaker, single vibrating shaft drive, can screening out 4 kinds of different specifications of the aggregate.
5. Measuring System
Measuring mixing composed by the aggregate balance, powder scale, scales and asphalt mixing cylinder, etc.
6.Mixing System
Improved the spacing of the agitator arms and the angle of the stirring blades, Mixing cylinder liner and blades is wear-resistant high strength chrome alloy castings, service life can reach to 105 batches or more.
7.Asphalt Heat And Heat Preservation System
This part is made of Insulation asphalt tank, Asphalt discharge tank, asphalt pump, integration of heat conduction oil furnace fuel type (Heat conduction oil circulation pump)
8.Control System
The whole mixing set control unit include hardware parts and software parts.
