Jaw crusher can be used to process ores and minerals with various sizes and discharge even materials. It is often used as primary and secondary crushing equipment in mine, metallurgic industry, chemical industry, building material, highway, railway, water conservancy, etc. Here is a question: Why is jaw crusher so called in mining industry?

Jaw crusher can be either and ore dressing equipment, sand and gravel equipment form a complete set, can also be used alone. Jaw crusher is also used for production of road foundation, road slag stone railway, and construction of sand and gravel aggregate. Existing jaw crusher (jaw broken) stone crushing plant features press jaw movement characteristics, can be divided into simple swing jaw crusher, complex swing jaw crusher and mixed type swing jaw crusher three forms.

Jaw crusher is the use of two jaw surface material extrusion and bending effect, coarsely chopped or crushed in the crushing machinery of various kinds of hardness of the material. The broken institution is composed of fixed jaw and movable jaw plate, when two jaw near the material being broken, when two jaw leave less than at the bottom of the material discharging mouth piece by education. Its fragile movement is intermittent. This kind of crusher with simple structure, reliable work, and can crush hard materials etc and are widely used in mineral dressing, building material, silicate and ceramic industries.

To 20 in the 1980 s, crushing, 800 tons of material per hour of large jaw crusher feed particle size is about 1800 mm. Commonly used jaw crusher with double bracket and the bracket of the two. The former dynamic jaw at work only as a simple circular motion, so it is also called simple swing jaw crusher. Who in be arc oscillating at the same time also be up and down movement, so also called complex swing jaw crusher.

In addition, to meet the requirements of different discharge granularity and compensation jaw plate wear, also add the discharging mouth adjusting device, usually between the bracket seat and back frame and put the adjusting shim or iron wedge magnetic beneficiation plant supplier. But in order to avoid impact to production due to replace the failure parts, hydraulic devices may be adopted to implement the insurance and adjustment. Some jaw crusher adopts hydraulic transmission to drive the moving jaw plate directly, to complete the material of broken. These two types of jaw crusher adopts hydraulic transmission device, often referred to as the hydraulic jaw crusher.
