Represent Jaw Crusher Specifications

How to represent jaw crusher specifications The specifications of jaw crusher are represented with a B and width to length l. For example, 900 1200 mm jaw crusher refers to the mouth width is 900 mm, and length is 1200 mm. According to the width of jaw crusher material inlet, it can be divided into large, medium and small three types. Material inlet width greater than 600 mm is large type that, width between 300 to 600 mm is the medium type and width of less than 300 mm is small type. In production, the biggest block should be smaller material feeding 15 to 20% than the inlet width B, that is the largest block D = 0.85-0.8B. Working Principle of Jaw Crusher This type of crusher adopts the electric motor as the power.

The eccentric shaft is revolved by an electric motor through v-belts. It causes the swing jaw to follow the preconcerted circle and crush the feeding materials, and then the material will be broken in the crushing chamber which is consisted of the stationary jaw plate, swing jaw plate and the liner plate. The materials are discharged from the lower part of machine. There are two common kinds of Jaw Crusher: dodge type and Blake type. Due to the throat width constant and often be keep so as to affect the normal work, the dodge typehas been eliminated. While Blake type is widely used in concentrator. Jaw crusher consists of the following major components: fixed jaw plate (the front wall of the rack, hanging in the axis of the movable jaw), eccentric shaft, vertical rod, brackets, drive flywheel, two jaw liners, levee, elbow board seat and adjusting block spring board.
