Jaw Crusher

Jaw Crusher

Jaw crushers are also called stone jaw crusher and PE jaw crusher, which have many outstanding features such as big crushing ratio, even product granularity, simple structure, reliable operation, simple and convenient maintenance and economical running cost.

 

Jaw crusher was first researched and developed in 1858. It was widely used in road paving projects at first, and then in mines. Jaw crushers have many outstanding features such as big crushing ratio, even product granularity, simple structure, reliable operation, simple and convenient maintenance and economical running cost. It is widely used in many industrial departments such as mine, metallurgy, building material, highway, railway, water conservancy and chemistry for crushing various materials whose compression strength less than 320MPa. The following picture is large jaw crusher and small jaw crusher or mini jaw crusher

Structure and Working Principle of Jaw Crushers

Jaw crushers is mainly composed of racks, eccentric shafts, belt wheels, flywheels, movable jaws, and side protecting plates, knee plates, and backseat of knee plates, adjustable screws, restoring springs, fixed jaw plates and movable jaw plates. Toggle plate is the most important secure part. This series of jaw crushing machine uses curved extrusion to smash. Motor drives belt and belt wheel through eccentric shaft to make the movable jaw to move up and down. When eccentric shaft moves up, the angle between toggle plate and movable jaw rise, forcing movable jaw to move close to fixed jaw plate, and the materials are crushed to debris; when eccentric shaft moves down, the angle between toggle plate and movable jaw drops, under the action of draw bar and spring, movable plate move away from fixed jaw plate, debris is discharged from crushing cavity at the same time. Continuous production can be realized along with continuous rotation of the motor and periodic extrusion and discharge of movable jaw.

Mini glass jaw crusher

With the continuous deepening of environmental awareness, the technical researches with circulation utilization of waste glass\waste glass bottles were enhanced in many countries in the world. The mini glass jaw Crusher in my company is the latest researched results basing on Germany technology Meanwhile Its performance has reached international advanced level.With the features of Big crushing ratio, uniform particle size;Simple structure, reliable operation and low operation cost;Convenient maintenance.In this way, the Life of the mini jaw crusher has been increased by two or three times.So it can considerably reduce production cost and boost economic benefit.
