Product Features

Mixing system

LB Series Asphalt Mixing Plant For Sale

The stirring system adopts the vibration stirring technology. The vibration stirring technology is designed and manufactured on the basis of the currently widely used twin-shaft mixer technology. The stirring shaft and the stirring blade are used as the vibration source. The implementation scheme of the combination of forced stirring and vibration strengthening. The general parameters of the vibration mixing machine are superior to the traditional mixing machine. At the same time, the vibration mixing technology is adopted to make the asphalt in the mixture more uniform and denser to bind the aggregate, effectively prevent the mixture from segregating, and the overall durability of the mixture is significantly improved.

Cold aggregate grading system

All hoppers are equipped with belt feeders controlled by variable frequency motors, which can adjust the ratio of a single hopper and all hoppers, increase measurement accuracy and reduce energy consumption, wide speed range, and high working efficiency. Each hopper discharge door is equipped with an alarm device for insufficient aggregate, which will automatically alarm if there is a lack of aggregate. A vibration motor is installed on the outer wall of the fine aggregate hopper to ensure the reliability of feeding, and specially designed self-cleaning equipment is installed. The belt conveyor adopts a jointless round belt, which runs smoothly and has a long service life. A round vibrating screen is installed between the belt aggregate and the belt feeder, which can initially filter out the aggregates of super large particle size to avoid affecting the normal work of dry rolling, aggregate elevator and vibrating screen due to the input of excessive materials .

Drying system

The drying drum is one of the key parts of the equipment of the entire mixing plant. Its drying ability directly affects the mixing ability of the aggregate and several other additives. The temperature of the aggregate also directly affects the temperature of the finished product. The drying efficiency also affects the combustion consumption. The influence is great, so the rational design of the structure of the drying drum is very important to reduce the production cost.

The drying drum consists of: a drying drum, a main burner, and a fuel supply system. The drying drum is frictionally driven by four motor reducers, with high driving efficiency and stable power. The external insulation layer and specially designed blades ensure maximum heat transfer to the aggregate and high thermal efficiency. Adopt international advanced brand burners, available fuels include diesel, heavy oil, light oil, medium, natural gas, etc. The temperature control system also uses well-known foreign brands to ensure the accuracy and reliability of temperature control.

Dust removal system

The two-stage dust removal system is adopted. The first-stage gravity dust collector has a simple structure and high efficiency. The second-stage cloth bag dust collector adopts a flat bag design, which has a compact structure and is easy to clean. The filter bag is made of refractory material. Can guarantee to meet the requirements of environmental standards. A high-low temperature alarm device and a high-temperature automatic flameout device are installed in the control system. The unique blowing system ensures the reliable operation of the dust removal system.
