Jaw Crusher Working Principle - 911 Metallurgist
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 produces less fines but the aggregates have a more elongated form. • Percussion crusher: The aggregates are produced by impact and hence,Characteristics and Comparison of Four Types of Jaw,,23/10/2020· The swing jaw reciprocates in a horizontal plane, and generally the angle between fixed jaw and movable jaw is of 20 °to30°. For blake-type crusher, its feeding area is fixed while discharging area is changeable. The greatest amount of motion is at the“Computer Aided Design of Jaw crusher” - 911 Metallurgist,Jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end. [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws .For instance, a 22 x 30 jaw crusher has an opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square.
