Jaw Crusher

Brief Introduction to Jaw Crusher

Jaw crusher is suitable for primary and secondary crushing of rocks with compressive strength of less than 320 MPa. It is widely used in mining, metallurgy, construction, highway, railway, chemistry industry, etc. All models are available according to your different fineness requirements.

Structure of Jaw Crusher

The jaw crusher mainly consists of the rack, bearing, operating mechanism, transmission mechanism (including eccentric connecting-rod, thrust rod, fly wheel and eccentric shaft), safety device, adjusting gear and so on.

Working Principle of Jaw Crusher

This series of crushers have a fixed jaw and a movable jaw, with the former fixed in front of the rack and the latter hanging on the mandrel. When the eccentric shaft rotates, the connecting rod moves from top to bottom, which makes the two thrust plates move repeatedly. With the pushing of the thrust plates, the movable jaw hanging on the mandrel can move from side to side. When the movable jaw sways to the fixed jaw, the material falling to the cavity will be crushed by the squeezing of the boards. When the movable jaw leaves the fixed jaw, the crushed material will be discharged from the discharge port under the cavity. Thus, the working of mobile jaw crushers is intermittent, with the processing of crushing alternates with that of discharging. Furthermore, since the movable jaw moves around the mandrel while it is working, the crushing ratio has always been 3 to 6. Due to its simple movement, this type of jaw crusher is also called simple swing type jaw crusher.
