Introduction

Jaw crusher is a machine used for crushing ores. The crushing process is a process to exert mechanical force on the solid materials and overcome the cohesion of the materials and make it broken into small-sized particles. According to the granularity of the crushed materials, the crusher equipment is divided into coarse crusher, medium crusher and fine crusher, and coarse crushers can also be called primary crushers. As jaw crusher is usually used for primary crushing, it can also be called primary crushers and primary jaw crusher.

Jaw crusher is widely used for the medium crushing of all kinds of ores and large-sized materials in mine, metallurgy, building material, highway, railway, water conservancy and chemistry. Jaw crushers, which are able to crush the materials into small-sized particles with even granularity, can be used together with sand making and ore beneficiation equipment, and also for producing road cornerstone and building sand and aggregate.

Features

Jaw Crusher

1. More advanced movable jaw assembly makes ire more durable. The movable jaw assemble is made of high-quality cast steel and is driven by two large-sized cast steel flywheel. In addition, the heavy type eccentric shaft is made of forging stock, which gives JC series of jaw crusher outstanding reliability.

2. The bearing pedestal adopts integrated cast steel structure. Integrated cast steel bearing pedestal can ensure the perfect fitting of the crusher frame, and at the same time, greatly increase the radial strength of the bearing pedestal, but split type bearing pedestal does not have these advantages.

3. The adoption of finite element analysis technology makes the crusher have higher strength.

4. The crushing chamber adopts symmetrical V structure, so that the actual feeding width is the same with the nominal feeding mouth.

5. The adjustment of the discharging mouth is faster and more convenient. European type JC series of jaw crusher is installed wedge block discharging mouth adjustment device which is simpler, safer and more convenient than that of traditional gasket adjustment device.

Principle

The electric motor drives the eccentric shaft to rotate by the V-belt and belt wheel, and the movable jaw will have extrusion movement along the fixed tractor driven by the eccentric shaft, thus realizing the crushing of the materials, and the crushed materials will be discharged from the discharging mouth.
