Product Description

Product Description

Structure

The core components of the roller extrusion granulator include two parallel-arranged rollers, transmission system, mould, cutting device and frame. When working, the two rollers rotate in opposite directions driven by the motor, and the material enters the gap between the rollers from the inlet. As the surface of the rollers usually has grooves or mould holes, the material is squeezed into the mould holes under high pressure to form a continuous strip. Subsequently, the strips are cut into granules of the required length by means of a cutting device. The whole process is continuous, highly automated and capable of mass production.

The design of the rollers is critical to the pelletising effect. Common roller surface configurations include flat, grooved and perforated rollers. Flat rollers are primarily used to compact material, grooved rollers are suitable for creating ribbons of pellets, and perforated rollers directly form cylindrical pellets. The size and shape of the holes in the moulds determine the appearance and size of the final pellets, and users can choose different sizes of moulds according to their needs. In addition, the rollers are usually made of high hardness alloy steel or wear-resistant materials to ensure the durability of the equipment under long-term high-pressure working environment.

Working Principle

 Power transmission: the belt and pulley are driven by the electric motor and transmitted to the active shaft through the speed reducer, and synchronised with the passive shaft through the pair of open gears, so that the two rolls work in opposite directions.
Material extrusion moulding: the material is added from the feeding hopper, and the material is forced into the gap between the two rolls by the running friction between the material and the rolls in the feeding system. Under the rotation of the rollers, the material will be brought in and extruded into pancake (sheet) shape.
Particle separation and screening: after falling down, the pancake-shaped material is broken into small particles by the crushing device, and then screened to get qualified particles.

Performance Characteristics

1, roller extrusion granulator for ammonium carbonate, ammonium chloride, monoammonium phosphate and other granulation effect is particularly good, the ball rate of up to 85%, without drying, less investment and quick return.

2, roller extruder without drying process, room temperature granulation, a moulding, less investment, quick results, good economic benefits.

3,Small power, reliable operation, no three-waste emissions, stable operation, easy maintenance, reasonable process layout, advanced technology, low production costs.
