Summary Of Asphalt Concrete Equipment

Summary Of Asphalt Concrete Equipment

1.1 Asphalt concrete is the concrete slab formed by mixing aggregate (sand, stone), binder (asphalt or residue) and filler (mineral powder) in a certain proportion. The mechanical equipment for mixing asphalt concrete is called asphalt concrete mixing plant.

1.2 Main uses of asphalt concrete mixing plant 
The equipment can produce asphalt mixtures, modified asphalt mixtures and color asphalt mixtures, which fully meet the needs of highway construction, grade roads, municipal roads, airports, ports and so on.

1.3 main function of asphalt concrete mixing equipment
Asphalt concrete mixing equipment is the key equipment of asphalt pavement construction. The application of asphalt concrete mixing station seriously affects the quality, progress and production efficiency of pavement construction.

1.3.1 Basic work completed by mixing plant
1.3.1.1 Raw materials, heating, drying, re screening and metering of cold mineral materials.
1.3.1.2 Heating, insulation, transportation and metering of liquid asphalt.
1.3.1.3 Transportation and measurement of fillers;
1.3.1.4 Hot aggregate, mineral powder and hot asphalt are evenly mixed and synthesized according to a certain mix proportion to meet the needs of finished product mixtures.

1.4 Structural types of asphalt concrete mixing station
The structure types of asphalt mixing plant are different according to different classification methods. Generally, it is classified according to the following situations:
It is divided into batch type and continuous type according to the production technology.
They are divided into fixed, removable and mobile modes.
The type of asphalt mixing equipment can be combined, such as removable batch, mobile batch and so on.

1.5 Part of asphalt concrete mixing equipment.
Asphalt mixing equipment is mainly composed of mixing system, drying system, combustion system, hot material lifting, vibration screen, hot material storage bin, weighing mixing system, asphalt supply system, powder supply system, dust removal system, finished material bin and control system.
Components: Grading Machine, Vibrating Screen, Belt Feeder, Powder Conveyor, Dry Mixing Drum, Pulverized Coal Burner, Dust Collector, Hoist, Product Storehouse, Asphalt Supply System, Distribution Room and Electrical Control System
