Basic Concepts Of Pulverizers

A crusher is a machine that crushes large-sized solid raw materials to the required size.
According to the size of the crushed material or crushed material, crushers can be divided into coarse crushers, crushers, and ultrafine crushers.
There are four types of external forces applied to the solid during the crushing process: shear, impact, rolling, and grinding. Shearing is mainly used in coarse crushing (crushing) and crushing operations, suitable for crushing or crushing materials with toughness or fibers, as well as large blocks of materials; Impact is mainly used in crushing operations, suitable for crushing brittle materials; Rolling is mainly used in high fineness crushing (ultra fine crushing) operations, suitable for most materials with different properties for ultra fine crushing operations; Grinding is mainly used for ultra-fine crushing or ultra large crushing equipment, suitable for further crushing operations after crushing operations.
The actual crushing process often involves several external forces acting simultaneously, but high-end crushers are tailored to the crushing environment.
