Boxin - Model BXE1 -PET Bottle Crushing Machine

Working principle and operation of plastic bottle crusher machine

Plastic crush machines are used throughout the plastic recycling industry to crush waste plastics into reusable raw materials. The following is the working principle of the plastic crusher and how it is applied:

Crusher box

• Manufactured using alloy structural steel, it is robust in design and built to withstand wearing out quickly. The two unchangeably fixed knives to be used positively and negatively are placed in the box and can be honed and regulated innumerably. This hinged screen frame not only enhances the convenience of removing the screen but is also designed to be detachable without using tools via a dedicated access point.

Scabbard

• tress relieved and dynamically balanced, sturdy and smooth running. The rotary knife has a V-shaped installation angle, the cutting shape is X-shaped, and the extension shaft of the rotor can be added with a speed wheel.

Rackmount

• Single-piece construction supports the entire frame on resilient rubber-metal bonded mountings to minimize vibration and noise.

Feed hopper

• The specially designed feed hopper can be filled manually or by conveyor belt and is fitted with a non-return plate to prevent backflow of material. The feed hopper is hydraulically opened for easy maintenance and cleaning of the rotor.

Electrical machinery

• The belt drive motor has a drive power of 55 kw, protection class IP-54, and a mains voltage of 380 V, 50 Hz, 3 phases.

Safety Limit Switches

• Ensure that maintenance equipment is at a complete stop.

Starter

• Automatic Y/? starting cabinet according to IEC standards, blocking the main switch and emergency stop.

Rotating grinding disk

• The grinding disk is also a key component in the plastic crushing process. The rotating high speed of the grinding disk and the blades’ crushing can quickly process the plastic materials into the required granular grinding state.

Screen Separation

• Plastic pulverizers usually have a screen separation device to obtain uniform plastic particles. The size of the plastic granules produced can be controlled by the different apertures of the screen, which is required for various applications.

Cooling system

Cursing the plastics when running at a very high speed will cause them to heat up. As a result, many plastic crushers have some cooling mechanisms to prevent overheating or degradation of plastic and guarantee the quality and constant behavior of the crushed pellets.
