plastic granulatorIt is a mechanical equipment that processes plastic raw materials or recycled materials into standard particles through processes such as melting, extrusion, cooling, and cutting. It is widely used in plastic recycling, modification, cable material production, and other fields。

Equipment structure and composition

Extrusion system: including screw, barrel, hopper, and mold. The screw is made of high-strength alloy steel, and the barrel is made of heat-resistant alloy steel composite pipe. The length is usually 15-30 times the diameter to achieve full plasticization.

Transmission system: composed of a motor and a reducer, it drives the screw and controls the speed and torque.

Heating and cooling system: using a combination of electric heating (resistance/induction) and air/water cooling, combined with temperature measuring devices for precise temperature control.

Auxiliary device

Including straightening device (to solve the problem of wire core eccentricity), cutting module (water-cooled pulling or die surface hot cutting), wire winding device, etc

1. ‌Equipment composition and working principle‌

• ‌host structureMainly composed of extrusion system (screw, barrel, die), transmission system (motor, reducer), and heating and cooling system (combination of electric heating and water/air cooling)The screw is made of high-strength corrosion-resistant alloy steel, and the barrel is made of heat-resistant alloy steel composite pipe. The length is usually 15-30 times the diameter to ensure sufficient plasticization1.

• ‌Auxiliary equipment and peripheral devicesIncluding cooling device (water tank/air ring), cutting module (water-cooled pulling or die surface hot cutting) and feeding system, some models integrate dehydration device (dehydration rate ≥ 95%)
