Crusher Classification

According to the D90 standard of required material fineness (90% of materials reach the predetermined fineness), crushers can be divided into crushers (below 60 mesh), pulverizers (60-120 mesh), and ultra-fine crushers (120-300 mesh). mesh), ultrafine grinder (above 300 mesh).
There are four external forces exerted on the material during the crushing process: rolling, shearing, impact (blow), and grinding. Rolling is mainly used for coarse and medium crushing, suitable for crushing hard materials and large materials; shearing is mainly used for crushing or crushing, suitable for crushing tough or fibrous materials; impact (blow) is mainly used for crushing and dissolving Polymerization is suitable for the crushing of brittle materials; grinding is mainly used for ultra-fine crushing and ultra-fine crushing, and is suitable for ultra-fine crushing after medium-fine grinding.
