Main Parts of DHB Series Asphalt Drum Mixing Plant:


 

1.Cold Aggregate Batcher

It can make aggregate material of four different sizes mixed well according to the construction requirement, for the oversized grain, it will be separated by the middle screen, and the qualified material will be conveyed into drying drum by tilted belt conveyer.

 

2.Mixing Mainframe

Integrated drying, heating and mixing in the whole part: the aggregate material will form an inadequate material flow in the drying section and go ahead promptly for preheating, and then it will form a sufficient material flow and heat quickly in the heating section. In the mixing section, the asphalt and will be sprayed into the aggregate material, which makes the aggregate material and asphalt mixing equably.

 

3.Burning System

Coal burner:

The high efficient coal crusher integrated with speed adjustable coal powder supply, it provides the coal powder with size of less than 50 micron far the burner. The burner adopts oil supply device and wind supply device, and can provide sufficient heat energy for the mixing plant.

Oil Burner:

The burner can use both diesel and heavy oil. Oil circuit system is separated with the burner body, safe and convenient and flexible. The working pressure of the oil pump is 12 bar, long service life, oil selection is wide.

 

4.Control System

The heat overload protect breaker is safe and reliable, the whole set control system is integrated on the operation platform, which is convenient and shortcut. The equipment has two operation modes: inter-lock operation and single-machine operation, which is convenient for equipment commissioning and production.
