The main crushers’ types
Stone Jaw crusher: The material is crushed between a fixed jaw and a mobile jaw. The feed is subjected to repeated pressure as it passes downwards and is progressively reduced in size until it is small enough to pass out of the crushing chamber. This crusher is usually for primary crushing.
Hammer mill crusher: The feed is fragmented by kinetic energy introduced by a rotating mass (the rotor) which projects the material against a fixed surface causing it to shatter causing further particle size reduction. This crusher produces more rounded shape.
Cone crusher: It uses a repeated compression action with fixed and moving crushing members. This kind of crusher produces less than 20% fines, and the aggregates are rather of cubic form.
Roller crusher: This crusher is composed of two cylinders rotating in opposite directions around two parallel axes.Double roller crusher is suitable for rough and intermediate crushing of brittle materials in such industries as cement, chemical industry, electric power, mine, building materials and metallurgy
