Step1: Plastic Crushing Machine Type

By Raw Material Classification

There are four kinds of plastic shredders for different plastics, including PET bottles shredder; PP, PE, etc. plastic film crusher; Hard plastic grinder; and Styrofoam crushing machine.

By Blade Shafts’ Number

Plastic shredders can be divided into three types(Single-shaft shredder, double-shaft shredder, and multi-shaft shredder) based on the number of blade shafts. The multi-shaft shredder features high output and is suitable for large-scale production scenarios. While the single-shaft shredder is more flexible and suitable for manufacturers with lower output requirements.

Step2: Capacities of Plastic Shredders

The plastic shredding machine’s capacities can be influenced by the following aspects:

Inner chamber sizes

The size of the crusher is determined by the size of the inner chamber. As shown in the figure below, the distance between the front and rear arms of the plastic crusher is the width of the crusher’s inner chamber. The width of the crusher generally ranges from 80 to 150 cm. The wider the crusher, the higher its output.

The Speed of the Crusher Pulley

The motor speed multiplied by the diameter of the small pulley next to it, divided by the diameter of the pulley on the crusher, is the speed of the pulley on the crusher. Within the reasonable range of 400 to 800 RPM, the higher the speed, the higher the output. Too low a speed may cause the machine to jam, while too high a speed may cause the machine to vibrate.

Design of Screens and Blades

Screens: The size of the crushed material is controlled by the mesh size of the screen. The mesh size of PET bottle flakes is usually adjusted to 16-18mm, while the mesh size of PVC plastic steel is around 30mm.
Blades: The thicker the blade thickness, the better. The gap between the blades should be small. For example, Shuliy’s shredder blades are about 10-30 mm thick, and the gap is usually between 0.2 and 1mm, which helps to increase the output of the shredder and improve plastic recycling efficiency.

Step3: Operation and Maintenance of The Best Plastic Shredder

Operation

Choosing a plastic shredder with a higher degree of automation can save on labor costs.

Maintenance

Choose a crusher that is easy to maintain and has low maintenance costs, for example, the blades of the Shuliy crusher are made of 60Si2Mn, which is durable and resistant to corrosion, thus extending the service life of the machine. Besides, Shuliy provides a one-year warranty, which increases the strong repair assurance.
