Product Details

simple small asphalt process plant

1.Application of Asphalt Plant

Asphalt mixing plant has highly accurate aggregate feeder, high quality mix, high production rate,excellent asphalt mixing plant.

The modular design and clearly defined interfaces between the asphalt mixing components allow the utilization of local manufacturing sources. The reduction of transportation and production costs is a direct benefit for our customers. The modular design and the preparation of the modules through the production lead to a fast and uncomplicated jobsite assembly.

2. Features and Advantages

2.1.Wide range of capacity choice. LB series asphalt batch mix plant is really the ideal plant for road maintenance and construction projects.

2.2 Accurately metering various materials ( aggregate, filler , bitumen), ensuring produce high quality hot mix.

2.3 Flexible configurations

2.4 Latest dust collection sections , modern recycling methods and excellent energy-saving insulation design could greatly reduce CO2 emissions.

2.5 Modular design. Each section with standard transport equipment of 2.5m height, easy to dismantle and transfer.

2.1 Drawing and working principle

3. Main Parts of Asphalt Plant

LB asphalt drum mixing plant mainly including: cold aggregate supply system, burner, drying and mixing drum, water dust catcher, bitumen supply system, electrical control system.

Drum mixing type asphalt plant, to continuously produce asphalt mixture.

Burning System: I. Oil burner; II. Gas burner; III. Coal burner; IV. Oil & Gas dual purpose burner.

3.1 The loop belt feeder for the measuring hopper and the heat-preservation drying drum

A. The loop belt feeder for the measuring hopper has a frequency-conversion speed regulator which can provide high and low speed. Its original structure facilitates belt change and makes material feeding more fluent, which reduces power consumption. Besides, there is a warning light which will remind the user when the machine uses up raw material.

B. The high-efficiency and heat-preservation drying drum and the special vanes make heat exchange more sufficient. Moreover, the high-efficiency and energy-saving imported burner can use both heavy oil and diesel, which reduces energy consumption.

3.2 The hot aggregate bin and main mixer

C. The hot aggregate bin is equipped with a continuous level indicator which enables the operator to know the level of material at a glance. The measurement of aggregate is conducted twice through large and small doors, which greatly improves the measuring precision. The unique structure of the material emptying door reduces the chance of blockage and will work more reliably.

D. The main mixing machine designed with European technology has double reducers with a high-speed synchronization capacity. Accurately-weighed asphalt can be directly pumped into the agitating kettle and powder material can be conveyed into the agitating kettle through the helix, which makes agitating more even and speedy. Besides, it has an opening to add wood fiber and an inlet to add used material to be recycled.

3.3 The dust-removing system and the control system

E. The dust-removing system adopts imported NOMEX bags which limit the density of dust discharged into the air within 50mg/m³, which is completely up to the national standard of environmental protection. The dust blown down will be collected into the collection tank through the dust lifter for reuse to avoid secondary pollution.

F. The control system adopts the SIEMENS integrated solution which plays a leading role in the industrial automation field. It also uses the PROFIBUS field bus to form a large and medium-sized distributed automatic system. In operation, the equipment adopts the technology of double hot standby on the industrial computer, dynamic display and buttonless design. All operations are done through the mouse. It has the real-time fault monitoring and control system with functions like parameter setting, data management and fault diagnosis. It measures precisely and can be controlled automatically, semi-automatically and manually, showing a stable and reliable performance.
