Working Principle of a Jaw Crusher A jaw crusher mainly works on the principle of reciprocating motion exhibited by the moveable jaw of the jaw crusher. The repeated movement of the jaws results in the development of compression force that further causes the breakdown of the rock or the ore placed between the two jaws into smaller pieces.
For primary crushing with a reduction ratio of 6 to 1. When a relatively coarse product is desired, top size usually larger than 38 mm (1 1/2) Closed Circuit Crushing System To control top size from a single crusher operating in an open circuit, material must remain in the crushing chamber until the material is reduced to top size.
