When plastic granulator is used, there will be no discharging. What are the causes? How should we solve it?
The materials are not plasticized well, the heater section is not working or the molecular weight distribution of plastic is wide. The operating temperature setting is low and unstable. There may be foreign materials that are not easy to melt. Replace and check the heater if necessary, and consult with the technologist if necessary. Verify the set temperature of each section; increase the set temperature value; clean and check the extrusion system and head.
If the original plastic granulator is normal, it is fed with iron or other things, or you put in a large piece of hard material to hold when you feed.
The speed of the main motor is uneven, the speed of the feeding motor is uneven, and the feeding quantity fluctuates. The treatment method is to check the main motor control system and bearings; check the power supply of the feeding system.
The causes of low lubricating oil pressure include low pressure setting of pressure regulating valve of lubricating oil system, oil pump failure or oil suction pipe blockage. The treatment method is to check and adjust the pressure regulating valve of lubricating oil system and check the oil.
