How to distinguish between a crusher machine, shredder machine and a grinder?

A Shredder machine is a machine that is used for fine grinding. It is usually used to process raw materials or scraps to make them smaller. Typical examples are plastic or rubber scraps that are torn apart and melted down to make pellets for remaking plastic bottles, tires, trash cans, etc... Shredder machine is used in the plastic recycling industry, commonly used for scrap large diameter PE plastic pipe, plastic film, a large pile of plastic sheets and broken head material.

The crusher machine generally deals with larger pieces of material with coarse grain size, usually larger than 8 mm. The structure is characterized by a certain gap between the broken pieces, not touching each other. crusher can be divided into coarse crusher, medium crusher, and fine crusher. Generally speaking, the grinding mill to deal with fine materials, product particle size is fine, up to 0. 074 millimeters, even thinner. Its structure is characterized by broken parts (or medium) contact with each other, the medium used is steel ball, steel bar, gravel or ore block, etc... But some machinery simultaneously has the crushing ore and the grinding function, like the autofill.

A Grinder is a machine that crushes large solid materials to the desired size. The crusher is composed of coarse crushing, fine crushing and pneumatic conveying devices, which can achieve the purpose of the crusher by the high-speed impact. The traditional screening procedure is canceled by using wind energy to make powder at one time. Mainly used in mines, building materials, and other industries.

According to the size of the material or the size of the crushed material can be divided into coarse crusher, crusher, ultra-fine crusher.

The external forces applied to the solid during the crushing process include shearing, impact, rolling and grinding. Shearing is mainly used in coarse crushing (crushing) and crushing operation, which is suitable for crushing or crushing tough or fibrous materials and large pieces of materials Grinding is mainly used in high fineness grinding (ultra-fine grinding), suitable for most of the nature of the material for ultra-fine grinding operations; grinding is mainly used in ultra-fine grinding or ultra-large grinding equipment, suitable for further grinding operations after grinding operations.
