Jaw Crusher Use for Stone Crushing Machine

Jaw Crusher Brief Introduction
Jaw crusher is mainly used as coarse crusher and medium crusher in mining, building materials, infrastructure and other departments.According to the width of the feed port, it is divided into three kinds: large, medium and small. The width of the feed port is larger than 600MM for the large machine, the width of the feed port is 300-600mm for the medium machine, and the width of the feed port is less than 300MM for the small machine.Jaw crusher is simple in structure, easy to manufacture and reliable in operation.
Jaw Crushing ratio is an important evaluation index to measure jaw crusher. Crushing ratio of jaw crusher is the ratio of raw material particle size and crushing product accuracy.It indicates the degree to which the raw material decreases after crushing.After the ore is crushed, the particle size becomes smaller. The ratio of the particle size before crushing and after crushing is called crushing ratio.It represents the multiple of particle size reduction after ore crushing.The crushing ratio can be calculated as follows:
1. Jaw crusher with the ore crushing before the maximum particle size and the maximum particle size after crushing to calculate the maximum particle size method in our country in the design of the concentrator often use this calculation method, because the design should be based on the maximum particle size to determine the jaw crusher feed mouth width
2.The Jaw Crusher ratio of the effective width of the feeding port and the width of the discharging port is not determined by the size of the discharging port for some jaw crushers.
3. Jaw Crusher Calculate the average particle size of the ore before and after crushing, also known as the average crushing ratio


Jaw Crusher Main Part

Jaw Crusher Rack
The frame is a rigid frame of four walls with upper and lower openings, which is used to support the eccentric shaft and bear the reaction force of the crushing material. It requires sufficient strength and stiffness. Generally, it is cast as a whole with cast steel.The frame of the mainframe needs to be cast in sections, and then firmly linked into a whole with bolts. The casting process is complicated.The frame of self-made small jaw crusher can also be welded with thick steel plate, but the stiffness is poor.
Jaw plate and side guard plate
The fixed jaw and the moving jaw are composed of a jaw bed and a jaw plate. The jaw plate is the working part and is fixed to the jaw bed with bolts and wedges.The fixed jaw bed is the front wall of the frame, and the movable jaw bed is suspended on the perimeter. It should have enough strength and stiffness to withstand the crushing reaction, so it is mostly cast steel or cast iron.
Jaw Crusher Drive 
The eccentric shaft is the main shaft of the crusher, which is made of high carbon steel and has huge bending torque.Eccentric parts must be finished, heat treated and bearing lining poured with Babbitt alloy.The eccentric shaft is equipped with a belt wheel at one end and a flywheel at the other end.
