Shredder principle and operation method

The shredder uses the interaction between the moving knife and the fixed knife to control the discharge particle size through the screen. The material is crushed, cut and extruded to process the material to a smaller size. It has the characteristics of small discharge particle size, replaceable screen, wide application range and high efficiency. It is widely used in resource regeneration, domestic waste derived fuel production, waste reduction and other fields.

The commonly used structure of the shredder mainly includes two axis shear type, single axis roller cutting type and coarse crushing tear type.

1. Shear shredder

Common is the shear crusher, there are two to four knife shafts, mainly rely on the principle of “cutting and cutting” to complete the crushing process, the principle of this crusher is to crush the object like scissors.

2. Roller cutting mill

The machine is equipped with a number of blades in a rotating knife roll, and the fixed blade is formed to cut, to complete the effect of crushing materials.

3. Tear type coarse crusher

The principle of the shredder is to swing the hook to tear the garbage material. This type is mainly used for rough crushing.

What is the use of shredder?

1. Collection of materials

Collect materials to be processed. Generally speaking. The material of the crushing equipment is garbage, plastic and other items that can be recycled in daily life. These materials are cheap to recycle and versatile.

2. Feed

Put the material into the shredding equipment. Control the operation of the equipment, and remove the torn materials after the shredding of the machine, and gather them into a pile, waiting for loading and delivery.

3. Recycle materials

Some customers are their own recycling material processing and then sell finished products, need to use the shredder to make materials into semi-finished products or finished products, which can save middlemen and material resources, environmental protection is also very good.

Shredder is a machine used for shredding, generally used to deal with raw materials or scraps, to make its size smaller. A typical example is the shredding of plastic or rubber scraps as raw materials to melt and then granulated, used to recreate plastic bottles, tires or trash cans, etc.
