The Working Principle of Mobile Jaw Crusher

Mar 14 2015

Mobile jaw crusher is a kind of mobile crusher. It has a wide application in mining, metallurgy, construction, road, rail, and other sectors. The compressive strength of its processed materials usually can not bigger than 320 MPA. Mobile jaw crusher has the advantages of large breaking ratio, good size, high production efficiency, etc. In the actual production, how does mobile jaw crusher complete the crushing operation? What is the working principle of mobile jaw crusher? Here I will give you a specific introduction.

The main crushing parts of m working principle of mobile jaw crusher

Mobile jaw crusher mainly depends on the two pieces of jaw plate’s extrusion force to crush raw materials into small pieces. The two jaw plates: one is the fixed jaw fixed vertically to the front wall of mobile jaw crusher. The other is the movable jaw, tilt. The mobile jaw and fixed jaw forms a crushing chamber which is big head and small foot.

The working principle of mobile jaw crusher

The mobile jaw of mobile jaw crusher moves up and down driven by the motor though pulley and eccentric shaft. When the mobile jaw rises up, angle between toggle plate and moving jaw will become big, thus contributing to the movable jaw close to the fixed jaw. Materials between these two plates will be squeezed, rubbed, and grinded. When the mobile jaw falls down, angle between toggle plate and moving jaw will be small. The movable jaw leaves the fixed jaw under the function of rod and spring. Then crushed materials are discharged from the outlet at the bottom of the crushing cavity. Raw materials are crushed once in each cyclical movement of the movable jaw. As the continuous work of motor, the movable jaw of mobile jaw crusher makes a reciprocating cyclical movement. The whole crushing process of mobile jaw crusher is done in this reciprocating cycle, thus achieving mass production.
