Description of Asphalt Premix Plant

LB1000 asphalt mixing plant is a product of contemporary international advanced level developed and produced by our company according to market demand. It is characterized by adopting modular structure, fast transportation, convenient installation, compact structure, small floor space, and high cost performance. The plant will not exceed 25 days from installation to formal production. The series of products are equipped with advanced automatic control and monitoring systems to make the equipment more reliable. The modular structure is designed in accordance with the national highway transportation regulations, and at the same time conforms to the railway transportation regulations, safe and fast.

System characteristics of LB1000 asphalt mixing plant

Cold aggregate supply system

Each bin is fed by a belt feeder controlled by a frequency conversion speed motor, which can realize single-bucket adjustment and overall proportional adjustment, with accurate primary distribution and low energy consumption. The sand bin is equipped with a silo wall vibrator for reliable material supply. The pulley adopts a specially designed "self-cleaning" roller, and the surface of the driving roller is glued to prevent the belt from slipping. The belt feeding system adopts a special anti-wear and anti-pinch design, and is equipped with high wear-resistant rib belts, which is safe, reliable, and long in life. The batching system can conveniently change the layout and feeding direction according to the user's site requirements

Drying Drum System

The drying system is mainly composed of drying drum, main burner, and fuel supply system. The drying drum adopts four decelerating motors, which are respectively connected with four friction wheels through a cross-head universal coupling, which has the advantages of installation error compensation, high transmission efficiency, and stable transmission. The drying drum is specially designed for the internal material-lifting blades, and the outside has an insulation layer, so that more heat can be transferred to the aggregate. The exhaust temperature at the tail of the drum is lower than 120℃, and the thermal efficiency is higher. The structure is compact and easy to adjust; diesel, heavy oil, residual oil, combustible gas, coal powder and other fuels can be used, which has good economy and adaptability. The advanced infrared temperature measurement and temperature control system ensures the accuracy and reliability of temperature control.

Filler supply system

The professionally designed double-layer arch breaking pneumatic blowing device for tank body and cone ensures uniform and continuous supply of filler. The special spiral butterfly valve is configured to ensure the weighing accuracy and automatic calculation and compensation of flying materials, and prevent dust from floating.

Weighing and mixing system

Aggregate weighing adopts the unique "secondary" weighing, which can realize coarse-fine weighing or direct fine weighing to ensure the weighing accuracy of various gradations. Asphalt is sprayed into the mixer at multiple points using a spray pump. The filler is conveyed into the mixer at multiple points by screw, thereby shortening the mixing time and improving the mixing efficiency. The liner and blades are made of high-strength wear-resistant cast iron, with a life span of more than 100,000 batches. The material door adopts a double-cylinder-operated rotary discharge door, which has short discharge time and good sealing effect. The drive of the agitator is driven by a double reduction motor, and the gears are synchronized.

Control System

The control system has the international advanced level, adopting the electrical components, programmable controllers and computers of international famous brands. Stable performance, easy to use, and reliable. Automatic, semi-automatic, and manual control of weighing, mixing, discharging, feeding truck operation, stop, etc. in the production process through computers and programmable controllers, and setting and modifying the ratio of asphalt mixture through computer screens. It can realize dynamic display and recording of weighing process, and print production records.

Application of Asphalt Mixing Plant (Asphalt Premix Plant) 

The asphalt concrete mixing plant produces asphalt concrete mixture. Mainly used on highways. The main function is to mix asphalt, crushed stone, mineral powder or filler and fiber in a certain proportion, and heat it to the mixing temperature for mixing.

Performance characteristics of LB1000 asphalt mixing plant

This equipment is particularly suitable for the maintenance of high-grade highways and the construction and maintenance of municipal and rural roads. The equipment transfer is fast and modular in design, and it is convenient to transport. Each module is not ultra-high or ultra-wide according to the transportation requirements, making the demolition and transfer of the equipment as easy as the installation of the equipment, which can effectively improve the construction efficiency and effectively guarantee The construction period requirements of the construction unit.
