Asphalt mixing plant, also can be called asphalt concrete mixing plant, asphalt concrete mixing plant. It refers to the complete set of equipment used for mass production of asphalt concrete. According to the mixing method, it can be divided into forced intermittent type and continuous production type; according to the handling method, it can be divided into fixed type, semi-fixed type and mobile type.

 

1. The main uses of asphalt mixing plant

 

Asphalt mixing plant, also known as asphalt concrete mixing plant, is a complete set of equipment used for mass production of asphalt mix, which can produce asphalt mix, modified asphalt mix, color asphalt mix, and is the necessary equipment for building highways, grade highways, municipal roads, airports and ports.

 

 

2. Components of asphalt mixing plant

 

Asphalt mixing plant is mainly composed of batching system, drying system, combustion system, hot material lifting, vibrating screen, hot material storage bin, weighing and mixing system, asphalt supply system, powder supply system, dust removal system, finished product bin and control system and other components.

Subdivision components are the following 12 points: 1. grading machine 2. vibrating screen 3. belt feeder 4. powder conveyor 5. dry mixing drum 6. coal dust burner 7. dust collector 8. elevator 9. finished product bin 10. asphalt supply system 11. distribution room 12. electrical control system.

 

3. Classification of asphalt mixing plant

 

1. According to the production capacity can be divided into: small, medium and large

Small: i.e. productivity below 40t/h.

Medium: i.e. productivity from 40 to 400t/h.

Large: i.e. productivity above 400t/h.

 

4. According to the handling mode (migration mode) can be divided into: mobile, semi-fixed and fixed

 

Mobile, that is, the silo and mixing pot with its own tires, can be transferred with the construction site, applicable to county and township roads and low-grade highway projects.

Semi-fixed, i.e. the equipment is installed on several trailers and assembled at the construction site, mostly used for highway construction.

Fixed, that is, the equipment operating location is fixed, also known as asphalt concrete processing plant, suitable for engineering concentration, urban road construction.

 

5. According to the process (mixing method) can be divided into: continuous drum type and intermittent forced type.

 

Continuous drum type, that is, the use of continuous uninterrupted mixing mode of production, aggregate heating and drying and mixing of the mixture in the same drum continuous.

Forced intermittent type, i.e. the heating and drying of aggregates and the mixing of mixes are forced to be carried out periodically. The equipment mixes separately in one pot, each pot is 45 to 60 seconds, and the output depends on the equipment model.

 

 

>Mobile asphalt mixing plant features

 

1. Modular design makes handling and installation faster and more convenient.

2. The unique design of mixing blade and the very power-driven mixing cylinder make the mixing easy, reliable and efficient.

3. Vibrating screen driven by imported vibrating motor, which greatly improves the efficiency and reduces the failure rate of the equipment.

4. Bag dust is placed in the drying state, placed above the drum, reducing heat loss, saving space and fuel.

5, the bottom of the silo placed relative to the structure, thus greatly reducing the footprint of the equipment, while eliminating the finished material lane lifting space, reducing the failure rate of equipment.

6. Lifting aggregate and the use of double-row plate lifting, increasing the service life of the hoist and improving the stability of operation.

7. the use of dual automatic control computer / manual control system with automatic fault diagnosis program simple and safe operation.
