sphalt mixing plant, also known as asphalt concrete mixing plant, refers to a complete set of equipment for the mass production of asphalt concrete. Asphalt concrete is an asphalt mixture 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. It can produce asphalt mixture, modified asphalt mixture, colored asphalt mixture.
Application of asphalt mixing plants
Asphalt concrete mixing equipment is a key equipment in asphalt pavement construction. It is very important equipment to build highways, grade highways, municipal roads, airports and ports. The quality of asphalt concrete mixing station seriously affecting the quality, progress and production efficiency of the pavement construction.

Components of asphalt mixer plant
Asphalt mixing equipment mainly consists of aggregate batching system, drying system, combustion system, hot material lifting system, vibrating screen, hot material storage silo, weighing system, mixing system, asphalt supply system, powder supply system, dust removal system, finished product silo and control system, etc.
Brief introduction of asphalt batching plant worlflow
1. first, the cold aggregates are batched, dried, re-screening and measuring.
2. heat, transport and measure liquid asphalt
3. Transport and measure the filler (mineral powder)
4. mix the hot aggregates, mineral powder and hot asphalt evenly according to a certain mix proportion to the desired finished product mixture.
Classification of asphalt mixing plants for sale
1. According to production capacity they can be divided into: small type, medium type and large type.
Small asphalt mix plants’ productivity are below 40t/h;
Medium-sized has the productivity of 40 ~ 400t / h;
Large-scale types have the productivity above 400t/h.
2. According to the mode of transport, they can be divided into: mobile type, semi-fixed type and fixed type.
Features of the mobile type: the material storage silo and the mixing system have their own tires, they can be transferred in the construction site. They are suitable for county and village roads and low-grade highway projects;
Features of Semi-fixed type: the equipment is installed on several trailers, and they will be assembled at the construction site. They are usually used for road construction;
Features of fixed type: the working site of this type equipment is fixed. It’s also known as asphalt concrete processing factory, suitable for engineering concentration area, urban road construction.
Among the above three types, the most popular in haomei machinery is mobile asphalt batch mix plant for sale. The following are its features:
1. The module design makes handling and installation faster and easier;
2. The design of the mixing blade is unique, making the mixing easier, more reliable and more efficient.
3. The vibration screen driven by imported vibration motor greatly improves the efficiency and reduces the failure rate of the equipment.
4, bag dust collector is installed above the drying system to reduce heat loss, save space and fuel;
5. double plate design in the hoist increases the service life of the hoist and improve the stability of the operation;
6, PC + PLC control system with automatic fault diagnosis process is simple and safe.
