The characteristics of plastics determine the processing equipment, and the cutting of plastic granulator is also a very important link. According to the different working mode and function of the granulator, it can be divided into two parts: eager and cooling, and eager can be divided into dry cutting, water ring cutting and underwater cutting. The selection of the structural mode of the granulator is inseparable from the color of plastic particles. It is very important to know the reasonable configuration of the type of plastic granulator. 1. Plastic granulator dry cutting process: dry cutting production that is, plastic granulator extruded strip material immediately after the rotating blade cut the length of uniform granular, and then the fan through the pipeline to send the grain to cooling, screening device. This method is suitable for the mixed cutting of polyvinyl gas. 2 plastic pelleting machine water ring cutting process: water ring granulation production that plastic pelletin

In the practical application of plastic pelletizer, there are often several abnormal phenomena, which will affect the orderly conduct of work. This paper gives some self-help troubleshooting methods for the frequent faults of plastic pelletizer, which greatly reduces the processing time of some faults, so as to ensure the long-term stable operation of plastic pelletizer, and also gives some guidance and reference to the operators of plastic pelletizer. Start the main motor, the main motor does not move or instant stop causes: 1. The main motor power is not connected 2. Insufficient heating time or a heater does not work, resulting in excessive torque, so that the motor overload treatment method: 1. Check the power wiring of the main motor 2. Check the temperature display of each section and find relevant records to confirm the preheating and heating time 3. Check whether the heater is damaged or poorly connected to the main motor power of the extruder

1. The thickness standards of pvc drainage pipes with different nominal inner diameters are different. The wall thickness of drainage pipes with nominal inner diameters of 90 is 3.0mm-3.5mm. 2. The wall thickness of the drainage pipe with nominal inner diameter of 110 is 3.2mm - 3.8mm. 3. The wall thickness of the drainage pipe with nominal inner diameter of 125 is 3.2mm - 3.8mm. 4. The wall thickness of the drainage pipe with a nominal inner diameter of 160 is 4.0-4.6 mm. 5. The wall thickness of the drainage pipe with a nominal inner diameter of 200 is 4.9mm - 5.6mm. 6. The wall thickness of the drainage pipe with nominal inner diameter of 250 is 6.2mm - 7.0mm. 7. The wall thickness of drainage pipe with nominal inner diameter of 315 is 7.8mm-8.6mm. 1. The surface hardness and tensile strength of pvc drainage pipe are excellent, so we say that its pipeline safety is very high. 2. The anti-aging property of pvc drainage pipe is also
