Introduction:

80TPH drum asphalt mix plant

1. DHB Series drum asphalt mixing plant, can produce various kinds of asphalt mixture, all system are controlled by the central control room.

2. This series mixer is suitable for the highway, black pavement construction for municipal department.

3. DHB Series asphalt mixing plant is including the three hoppers grading machine(mobile or stationary),Four hoppers grading machine(mobile or stationary).dryer drum (mobile or stationary),belt conveyor ,coal burner devices ,deducting system. Elevator, storage silo, asphalt heating system, electric control system

4. DHB Series asphalt plant has the simple construction, mobile flexible, ratio of precision,good effect of dust removal and maintenance

I. Technical performance index

1. Production capacity: 80TPH

2. Electric voltage: 380 V 50 HZ

3. Control mode: Centralized control

4. The max aggregate grain size: ≤25mm

5. Total assembly motor power: 132kw

II. Specification- 80 tph drum asphalt mix plant

1. Grading machine

Components

Hoppers, chassis, small size belt conveyor, aggregate belt conveyor, motors and base plate

Function

The function of the grading machine is proportioned for raw materials.

2. Belt conveyor

Components

Chassis, main roller and passive roller

Function

The function is transferred the mixture into dryer drum continuously and uniformly. The degree of tightness and excursion can be adjusted by tension device and prevent slant gear roller.

3. Dryer drum:

the dryer body should be supported by four fiction gears (should be positioned by gear wheel),the guide plate ,lifting blade and shoveling plant are equipped in the dryer drum, the base plate chassis motors and smoke box elevator are consisted of the outside shape. It adopts the drive mechanism to the friction by two groups motors, and heating the mixture uniformly. This mixing assembly adopts slanting type single plate chain for lifting.

4. Asphalt supplying system

Components:

Bitumen tank, heating device, bitumen pump, steam boiler, thermo detector and transmission pipeline,

Function

The function is providing the suitable temperature of bitumen for the mixture in the mixer.

5. Coal burning system

Components:

Coal pulverizer, furnace hearth combustor, air blower, oil pipeline, coal conveying system.

Function:

The function of coal burning system is providing the heating resource for dryer drum. Coal powder lot volume should be adjusted by the temperature, which showed in the instrument. The volume of the air provided should be controlled by the hand shank.

6. Deducting system

Type:

Cyclone dust removal and water film cyclone.

Components:

Air hose, air blower, water pump, dust collector.

Function:

Increasing the differential pressure of the dryer drum, provide the high temperature air flow exchanged, to achieve the high temperature quickly. And reduce the off gas and dust discharge for the environmental friendly.

7. Elevator:

Components:

Chassis shell, lifting plate chain, chain wheel, and motor reducer

Function:

Lift the mixture to the certain height level, easy to discharge.

IV .Principle

Different dimension stone should be proportioned (the dimension stone is loaded into the different hoppers of the grading machine by the loader, and proportioned,the mixture should be transferred into dryer drum by belt conveyor and uploading belt ,the cold aggregate should be heating and mixing uniformity in the dryer drum. At the same time, the 120º-160ºmixture should be mixing with the bitumen ,where the bitumen is spraying by the bitumen pipeline behind the smoke box of dryer drum,the mixture finished goods should be produced ,and transported to the finished goods silo by elevator . Waiting for loading, is adopted the concurrent type, this means, upper front of the dryer drum, used for feeding, and heating in the front of dryer drum.

Regulate

1. Coal burner device is regulated ,the temperature of the finished goods should be controlled ;

2. Motor of grading machine is regulated , the capacity should be controlled ,increased or decreased;

3. The oil stone ration of finished goods should be controlled by the flow rate of asphalt.
