Jaw crusher is basically a machine which utilizes two steel plates for crushing. There are two different kinds of jaw crushers. They perform the same action but by using different techniques. Over head eccentric and double toggle are the two main types of these crushers. Double toggle model consists of stationary jaw, swing jaw, offset eccentric shaft, double set of toggles and pivot point, Whereas overhead eccentric type consists of adjusting wedges, flying wheel, Pullman, hydraulic rams, crushing chamber and a sizing gap. The movable and the static plates move together to crush the dropped rock material between them.

Structural Mechanism: They are made up of steel structure. Jaw crushers consist of an eccentric shaft which is made up of high quality forging steel. This machine has high rigidity level. They have very high intensity level. Bearings of jaw crushers are automatically adjustable. Jaw crushers normally consist of two jaws. One jaw is stationery and other one is movable. These both jaws are made up of magnetic steel.Crushers are specifically designed for conversion and reduction of huge rocks into smaller stones for further usage in industry. Crushers have a metal surface which is utilized for compressing and breaking of materials. Moving jaw is driven by the belt which is powered by the motor. Fixed jaw is basically surrounded by the eccentric shaft to do periodic motion. One thing which is the most important is the angle between toggle plate and the moving jaw. This angle changes when the plate and jaw moves.

Key factors: Factors in determining a jaw crusher’s choice may be dimensions of chamber, design and material of the stationary plate, size of the opening, material humidity, material hardness, material components, materials fineness and materials viscosity. These all are the key factors of jaw crushers. Shanghai Shibang is the famous jaw crusher supplier of the world.
