pelletizer is main auxiliary equipment of plastic recycling extruder machine. According to their work and the role of different, it can be divided into two parts of hot cutting and cooling, and hot cutting can be divided into dry cut, water cut and underwater cutting and other structural methods, their specific working methods and application characteristics are as follows.
1, water ring cut off water ring plastic recycling extruder machine production method refers to the plastic particles extruded strip material immediately rotating blade cutting, and throwing attached to the inner wall of the shear hull high-speed rotation of the water ring, and then the water to the material To the water separator dehydration, dry and then sent to the material cooling device cooling, that is finished. This production method is suitable for the granulation of polyolefin materials.
2, dry pellet plastic recycling extruder production method refers to the plastic particles in the extruded strip immediately after the rotation of the blade cut into a uniform length of the shape, and then by the fan through the pipe to the cooling material to the cooling, screening device. This pelletizing method is suitable for agglomeration of agglomerates.
3, cold pelletized cooling particles refers to the granulation machine plastic granule machine after mixing the material, from the barrel before the molding mold in the forming sheet material, first fall into the water in the cooling and cooling after the coiling, and then It is suitable for the mixing of raw materials of polyethylene, polypropylene, ABS and polyethylene terephthalate.
4, underwater cut water under the pellet production method refers to the plastic particles extruded into the water immediately into the water cooling, and then cut into pull material. And then by the circulating water to the centrifugal dryer to the dehydration, dry operation. This kind of cutting method is more suitable for twin-screw plastic pellet kneading raw materials pelletizing, for the larger batch of the most production.
