Description

PE plastic powder is also called PE powder coating. It is based on PE resin and added with additives such as pigments, stabilizers and lubricants. It is used for anti-corrosion powder coatings of pipes, guardrails and hardware.

The PE plastic powder mill is one of the most important production equipments, which has a great influence on the quality of the finished product. Due to the low mechanical strength and excellent toughness of PE resin, it is difficult to grind it by ordinary pulverizers. Under the vibration of the vibrating feeder, the PE plastic particles to be ground evenly enter the grinding chamber. After grinding, they are drawn into the cyclone separator by the negative pressure in the pipeline. The air is discharged upward, and the powder falls to the vibrating screen. The screen is too thick. The powder continues to enter the grinding chamber for grinding again, and the fineness is suitable as the product into the packaging bag. At present, there are mainly two types of disc mills and cutter disc mills. Their principles are shearing and impact force to convert particles into fine powder.

Structural features:
A1: The new tool structure, strong collision between materials, shearing and crushing of the fixed blade plate under the action of the high-speed centrifugal force of the rotating blade.
A2: The combination of air and cold water cooling effectively controls the material crushing temperature and solves the problems of deterioration, melting and carbonization of heat-sensitive plastics after crushing.
A3: The grinding chamber of this machine can be opened, which is convenient for maintenance and replacement of tools.
A4: Equipped with vibrating screening equipment, materials that do not meet the requirements are returned to the mill for re-grinding.
A5: Equipped with negative pressure feeding and dust removal device, which can improve the material discharge speed, avoid the wear of the fan impeller caused by the positive pressure discharge in the past, and remove the dust during the milling process. effective recovery.
A6: The electrical control part adopts the star-delta starting method to reduce the starting current and increase the service life of the motor.
