The cutting method of HDPE hollow barrel granulation machine is that the plastic is extruded in the melt state, cut by the rotating blade, and cooled and solidified by circulating cooling water.
The cutting method of HDPE hollow barrel granulation machine is that the plastic is extruded in the melt state, cut by the rotating blade, and cooled and solidified by circulating cooling water. The finished material is dehydrated by a high-speed dehydrator, which can effectively remove water and dust on the surface of the granule, with good drying effect and easy operation in the pelletizing process. HDPE hollow barrel granulation line has a higher degree of automation, no dust, low noise, good slice quality, and beautiful appearance.
1. The extrusion system is mainly composed of a barrel, screw, die and filter. Its function is to plasticize plastic raw materials in film, granular, powder, block or other shapes into a uniform melt under the action of temperature and pressure, and then be fixed temperature, pressure, quantitative and continuous from the die by the screw Squeeze out.
2. The transmission system is mainly composed of motor, gear reducer and belt. Its function is to drive the screw, and make the screw obtain the necessary torque and speed under the given process conditions (such as temperature, pressure and speed, etc.) and can rotate the roll evenly to complete the extrusion process.
3. The heating and cooling system is mainly composed of a heater, a cooling device outside the barrel, and a cooling device inside the screw. Its function is to ensure that the extrusion process is completed within the temperature range required by the process by heating or cooling the barrel, screw and other components.
4. The feeding system of the hollow barrel granulation line is mainly composed of a hopper and an automatic feeding device. Its function is to provide the required materials to the extrusion system steadily and continuously.
Normal:
| Model | SJ45 | SJ65 | SJ90 | SJ100 | SJ120 |
| Output(kg/h) | 10-60 | 100-150 | 180-250 | 250-350 | 300-600 |

Extruder
A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 36D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with water content
Water-ring Die-face cutting system
Water-ring die-face/Strand cutting methods are usually adopted. In water-ring die-face cutting system, the rotary cutting blades will be pneumatically fit completely and closely to the die-face surface to ensure efficient cutting. Rotary speed of the blades is automatically adjusted by module system according to melt pressure at the die face.
Vibration drying system
Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.Combine crushing, compacting and plletizing steps in one system, less-labor cost.Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;Higher output and lower energy consumption
