For instance, claw – shaped knives are more suitable for crushing hard plastics, while flat – shaped knives can produce more uniform plastic particles.

Screen

The screen is used to control the size of the crushed plastic particles. It can be replaced with screens of different sizes according to the requirements of the subsequent processing. The aperture of the screen determines the size of the crushed particles. In addition to controlling the particle size, the screen can also remove impurities in the plastic, making the final plastic product more pure.

Motor

The motor is the power source of the plastic crusher. It provides the necessary energy to drive the rotation of the crushing knives. The power of the motor depends on the size and capacity of the crusher. High – power motors are usually required for large – scale plastic crushers to ensure efficient crushing. The motor should be installed at the back of the crusher, and its rotation direction should be set according to the design requirements of the crusher.

The main electrical appliances in the control system are often well – known brands, such as Schneider and Siemens, to provide reliable circuit control.

Carrying Box

The carrying box of the plastic crusher is designed with front and rear sound – insulation and soundproofing features, which can significantly reduce the noise generated during the crushing process. The design of the carrying box is simple, with a small floor space and easy maintenance. The door of the carrying box is separated from the design, making it very convenient to clean and change the screen.

Working Principles of Plastic Crusher Equipment

The plastic crusher drives the cutter head to rotate at high speed through the motor. During the high – speed rotation of the moving knife, it forms a relative movement trend with the fixed knife. The gap formed between the moving knife and the fixed knife is used to cause the cut of plastic crushing and shearing, so as to crush large pieces of plastic. The crushed plastic is filtered through the screen to output plastic particles of the desired size. Under the action of the internal air flow, larger plastic materials are turned up again and enter the shearing port for further crushing until they meet the size requirements.

Types of Plastic Crusher Equipment

Hard Plastic Crushers

Hard plastic crushers are designed for crushing hard plastics, such as ABS, PE, and PP boards. They usually have a rectangular feeding port, which is convenient for feeding long – strip plastic boards.
