Jaw Crusher jaw plates is the use of two extrusion of material and bending role, rough or broken pieces of the broken variety of mechanical hardness of materials. His broken body from the fixed jaw plate and movable jaw plate of the board when close to the jaw when the two materials was broken, when the two left jaw plate nesting less than I expected to block the discharge from the bottom. Broken its action is carried out intermittently. Crusher because of this simple structure, reliable work can be broken and the advantages of hard materials and are widely used in mineral processing, construction materials, silicate and ceramic industries.
80 to 20 during the 20th century, 800 tons of material per hour broken large jaw crusher has a feed size of about 1,800 mm. Commonly used Jaw Crusher has双肘plate and two single toggle plate. The former moving jaw at work only to make a simple swing of the arc, it is also called a simple swing jaw crusher; swing arc for the latter at the same time also for the whole movement, so complex, also known as swing jaw crusher. E crusher used in mining, smelting, building materials, roads, railways, water conservancy and chemical industry and many other departments, non-breaking strength of more than 320 different kinds of materials MPa.

E-plate single toggle jaw crusher motor plate up and down movement to promote the role of nesting, and the upper part of the trip is greater than the lower level, large pieces of material easily broken, so the efficiency is higher than双肘broken plate. Its disadvantage is that the jaw plate wear faster, and the materials have been crushed by the phenomenon of increased energy consumption. In order to protect important parts of the machine does not overload and damage, often a simple shape, smaller size designed to bracket the weak links, overload the machine when it first occurred in the deformation or fracture.
In addition, to meet the needs of different size nesting requirements and compensation jaw wear plate, but also additional nesting population adjustment device, usually in the elbow after the board seat and put rack adjustment gasket between the iron or wedge. However, in order to avoid loss due to the replacement of broken parts to affect the production, the hydraulic device may also have recourse to insurance and adjustment to achieve. Some jaw crusher directly used to drive hydraulic jaw plate move in order to complete the action broken materials. These two types of devices using hydraulic jaw crusher, often collectively referred to as hydraulic jaw crusher.
