Introduction to Asphalt Mixing Plant

Nov. 27, 2019

As an Asphalt Plant Supplier in China, I would like to introduce you to the asphalt mixing plant, which can also be called asphalt concrete mixing station and asphalt concrete mixing station. Refers to a complete set of equipment for mass production of asphalt concrete.

[1] According to the mixing method, it can be divided into forced intermittent type and continuous production type;

[2] According to the handling method, it can be divided into fixed, semi-fixed and mobile.

Asphalt Mixing Plant

Asphalt Mixing Plant

The main purpose

Asphalt Mixing Plant, also known as asphalt concrete mixing station, refers to a complete set of equipment for mass production of asphalt concrete. It can produce asphalt mixture, modified asphalt mixture and colored asphalt mixture. It is used to build highways, grade highways, municipalities. Necessary equipment for roads, airports and ports.

Machine component

Asphalt mixing equipment mainly consists of batching system, drying system, combustion system, hot material lifting, vibrating screen, hot material storage bin, weighing and stirring system, asphalt supply system, powder supply system, dust removal system, finished silo, and control system, etc. Part of the composition.


(1) Grading machine (2) Vibrating Screen (3) Belt feeder (4) Powder conveyor (5) Dry mixing drum;

(6) Pulverized coal burner (7) dust collector (8) Elevator (9) Finished silo (10) Asphalt supply system;

(11) Power distribution room (12) electrical control system.

Equipment classification

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

Small, that is, the productivity is below 40t/h;

Medium-sized, that is, productivity is 40-400t/h;

Large, that is, the productivity is above 400t/h.

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

Mobile, that is, silos and mixing pots with their own tires, can be transferred with the construction site, suitable for county roads and low-grade highway projects;

Semi-fixed, that is, the equipment is installed on several trailers, assembled at the construction site, and used for road construction;

The fixed type, that is, the fixed working place of the equipment, also known as the asphalt concrete processing factory, is suitable for engineering concentration and urban road construction.

3. According to the process flow (stirring method) can be divided into: continuous drum type and intermittent forced type.

The continuous drum type is produced by continuous uninterrupted stirring, and the heating and drying of the aggregate and the stirring of the mixture are continuously performed in the same drum;

The forced batching, that is, the heating and drying of the aggregate and the stirring of the mixture are forced to be periodically performed. The equipment is stirred separately in one pot and one pot, and each pot is stirred for 45 seconds to 60 seconds. The yield depends on the model of the equipment.

Mobile Type Asphalt Mixing Plant Features:

1. The module design makes handling and installation quicker and more convenient;

2. The mixing blade is unique in design, and the stirring cylinder with very power is more convenient, reliable and efficient.

3. The vibration screen driven by the imported vibration motor greatly improves the efficiency and reduces the failure rate of the equipment;

4. The bag is dusted and placed in a dry state, placed above the drum to reduce heat loss, saving space and fuel;

5. The bottom structure of the silo is relatively opposite, thereby greatly reducing the floor space of the equipment, and at the same time canceling the lifting space of the finished product small lane and reducing the equipment failure rate;

6. Improve the aggregate and adopt double-row plate lifting, which increases the service life of the hoist and improves the running stability;

7, Using dual-machine automatic control computer / manual control system, with automatic fault diagnosis program is simple and safe to operate
