This plastic granulator is an essential machine for plastic recycling granulating line, mainly for recycling waste plastic film, PP, and PE flakes.
The plastic granulator is widely used in the waste plastic recycling industry and is well supported and favored by customers. To ensure that the plastic granulator works properly, a test run is required.
Plastic Granulator’s Test Operation Rules
Different materials have different processes. The following is an example of pe film material. The specific operation is performed according to the actual process.
1, Turn on the electricity and water and check if they are normal, and if there are any abnormalities get maintenance staff to overhaul them in time.
2, Preheat. Turn on all the heating switches in the heating area of the main control cabinet for 1 hour, including the heating area of the main unit, the auxiliary unit, and the heating switch of the die head.
3, Test run. After the screw has preheated for about 1 hour, turn on the electromagnetic heating and set the temperature at about 150°C. Start the main machine, feed slowly and manually, and stop the main machine when the motor sound is dull due to heavy load.
Turn on the electromagnetic heating again and set the temperature to around 220°C. Start the mainframe, feed slowly, and stop the mainframe when the head of the mainframe screw is discharged.
Electromagnetic heating is turned on again, setting the temperature around 280℃-300℃. Start the main machine and the secondary machine, and feed slowly, when the head of the secondary machine screw is discharged, observe the degree of ripening of the discharged material (the secondary machine die head is in the open state). Put it into the water to cool down, fold it back to the feed port of the secondary machine, and stop the main and secondary machines when the material has reached the process requirements.
4, Install the die filter screen. The main and auxiliary motors are started, the plastic granule cutter is started, the strands enter the plastic granule cutter, and the pellets are discharged for about 0.5 hours, and all heating in the control cabinet is turned off (including the host machine heating area, auxiliary heating area and die head heating), only electromagnetic heating is reserved.
5, After the discharge is normal, the production line runs normally.
