What is a plastic shredder

1, What is a Plastic Shredder?

With the application of many plastic products in our daily life, more and more waste plastic is generated yearly. However, only 10% of waste plastic worldwide will be recycled and reused. The rest will be buried or incinerated, which wastes resources and pollutes the environment.

A plastic shredder is a solid waste reduction machinery and environmental protection equipment for shredding high-density polyethene HDPE plastic products and materials to facilitate plastic recycling and recycled plastic granules. For example, mineral water bottles, PET bottles, motor oil bottles, gasoline bottles, plastic barrels, etc.

A plastic shredder, also called a single-shaft crusher, single-shaft shredder, is use dynamic knife particles and fixed knife interaction, and through the screen to control the size of the material, the material will be shredded, sheared, and extrusion to process the material to a smaller size. It is often used for the fine crushing of various solid wastes. It can process the materials to a smaller size at one time, widely used in resource recycling, RDF (domestic waste-derived fuel) production, waste reduction, and so on. It features a small discharge size, replaceable screen, wide applicability of materials, and high efficiency.

The plastic shredder can shred HDPE/PVC/PP/PE waste plastic, which effectively improves the recycling efficiency of plastic waste. PACKER plastic shredders can be customized according to the characteristics of different plastics to achieve high efficiency, low energy consumption, low pollution, low noise, and uniform discharge.


2, How does the Plastic Shredder Works?

How the plastic shredder works

A plastic shredder is a shredding machine for coarse shredding. Generally, a single-shaft or double-shaft plastic shredder works at a low rotation speed. Cutter heads in plastic shredder cut and shred plastic. Low speed and strong working conditions can achieve a very good shredding effect on plastic products.

A plastic shredder comprises four parts: a shredding mechanism, a bracket, a recycling box, and a pulling cart. The size of the equipment is determined by the size of the material and material handling capacity. A plastic shredder is designed with a filter device inside; when the plastic shredder works normally, the filter plays a role in separating the material and liquid, effectively recycling the liquid left on the bottle.

The cutter head of the plastic shredder is connected to the worm gear reducer motor installed on the driving shaft. It is transmitted to the driven shaft through the speed reducer. The moving knife on the driving shaft forms relative motion with the stationary knife disc on the casing. The spiral tooth cutter discs on the main shaft are staggered. After the plastic product enters, it is squeezed, torn, and sheared simultaneously so that the plastic is shredded.


3, Types and Choice of Plastic Shredder Blades.

Types and choice of plastic shredder blades

The single-shaft plastic shredder blade, as the name suggests, is installed on the shaft of the single-shaft plastic shredder and is called a moving knife. The shape is square, the four sides of the knife edge are curved, the middle tapping hole, and the part from the knife edge to the middle hole is recessed inward, which is used with the fixed knife on the knife holder.

The multi-shaft plastic shredder blade is a claw knife, which is installed on the double-shaft plastic shredder according to each company's design. Generally, it can be divided into a 3-claw shredder blade, an 8-claw shredder blade, a 12-claw shredder blade, etc. It is used for shredding, tearing, and squeezing to reduce the size of materials. This plastic shredder blade is widely used in the shredding of waste plastics, waste rubber, wood, and other bulky wastes.

The material of the plastic shredder blade is generally 9crsi, Cr12MoV, SKD-11, and D2.

9CrSi is an alloy tool steel. This material has high tool hardness and good wear resistance but is more brittle. It is suitable for soft waste materials such as rubber, fibre, and paper.

Cr12MoV and SKD-11 are cold work die steels. These two materials have similar properties and strong wear and impact resistance. They are suitable for shredding wood, waste furniture, and plastics with high hardness.

D2 is a high carbon and chromium steel with excellent rust resistance, flexibility, and high stability, but not easy to grind.
