DHB 20 Asphalt Drum mix plant

Asphalt Drum Mixing Plant

 Asphalt Drum Mixing Plant mainly including: cold aggregate supply system, burner, drying and mixing drum, water dust catcher, bitumen supply system, electric control system. There are two types about it.Mobile Type: MDHB series;Stationary Type: DHB series

Main Characteristic

Modular design, installation, maintenance,convenient maintenance and transitions; Electromagnetic or frequency control of motor speed with high precision, long life,with a sieve,except without the material, reducing heat loss; Drying cylinder driven by single motor gear mesh, smooth transmission, low vibration, low noise, copy board design is unique, in the aggregate heat exchange, high thermal efficiency, using water film dust removal, accord with environmental protection requirement. Using coal as fuel, reduce the cost of 50-80%,this products is a variety of series, for user selection.

1 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 & single-machine operation,which is convenient for equipment commissioning and productions.

2 Cold Aggregate Supply System

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

3 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 sections, the asphalt and will be sprayed into the aggregate material, which makes the aggregate material and asphalt mixing equably.

4 Coal Burning System

  The high efficient coal crusher integrated with speed adjust 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.

5 Bitumen Pot-heating Equipment

Pot storing of bitumen, heat partially(heat pot in pot), and the bitumen is heated rapidly, prevent the bitumen from being heated repeatedly at the same time, further save the energy, guarantee the quality. Preheat the high-temperature bitumen at relatively close state, reduce the operation procedure greatly, and reduce the operation procedure greatly,shorten the heating time, save energy, and reduce the production cost of the high-temperature bitumen.

Drum asphalt Mixing Plant characteristics:

Modular design,installation,maintenance,convenient maintenance and transitions;Electromagnetic or frequency control of motor speed with high precision,long life,with a sieve,except with out the material,reducing heat loss;Drying cylinder driven by single motor gear mesh,smooth transmission,low vibration,low py board design is unique,in the aggregate heat exchanger,high thermal efficiency,using water film dust removal,accord with environmental protection requirement.Using coal as fuel,reduce the cost of 50-80%,this product is a variety of series,for user selection.

 Application

 DHB series mobile asphalt drum mixing machine is the machinery for producing all type of asphalt mixed materials,applied in high way,urban road,airport,boatyard,car park,goods yard etc. The equipment has the characteristics as follows: Advanced techniques, rational and compact structure, convenient operating, is easy to move, saving transit expenses. This machine has accurate mixture ratio, high production efficiency, low energy consumption and low pollution. The performance is in full compliance with industry standards.
