Marble lines cooling device is for what

Marble lines cooling unit is to ensure that the plastic is set in process the required temperature range. In order to exclude specific screw rotating shear friction produced excess heat, to avoid high temperature decomposition of plastic and scorch or stereotyped difficulties. Are water cooled and air cooled two types of barrel cooling, generally small and medium sized extruder is used in air cooling is more appropriate, large-scale use of water or combination of two forms of cooling. Screw is used in cooling water away from the Center, to increase material solid conveying ratio of stability and the plastic output is at the same time improving the quality of products. But cooling in the hopper is designed to strengthen the role of solid material transportation to prevent warming grain sticky plastic plug discharge port. Second, in order to ensure transmission parts work properly.
