High quality Small capacity Jaw Crusher

Introduction of Jaw Crusher

PE series Jaw crusher is mainly applicable to various ores and big blocks in primary and secondary crushing, is widely used in mining, quarry, metallurgy, building, highway, railway, construction waste processing, water conservancy and chemical industry, etc. The maX compression resistant of be curhser material is 320Mpa. It features in high reduction ratio, easy operation, simple construction, repeatable performance, easy maintenance, and low consumption.

Working Principle of Jaw Crusher
The working manner of this series crushing machine is dynamic extrusion type, and its working principle goes like this:
The electro motor drives the belt and belt wheel to make the movable jaw to move up and down through the eccentric shaft, and then movable jaw goes up, the angle between the toggle pate and the movable jaw is bigger, thus pushing the movable jaw to get close to the fixed jaw, and at the same time, the materials are crushed or smashed, thus reaching the goal of crushing.
When the movable jaw goes down, the angle between the toggle pate and the movable jaw is smaller, under the effect of the draw bar and the spring, the movable jaw moves always from the fixed jaw, and then the crushed materials will be discharged out from the lower mouth of the crushing chamber.
With the continuous rotation of the electro motor, the movable jaw of the crusher will do periodic motion to crush and discharge the materials, thus realizing mass production.

Structure of Jaw Crusher

The basic structure of a jaw crusher generally includes seven parts, such as driving medium, rack, the jaw plate and side rack, flywheel, lubrication device, adjusting device and the reset spring.
1. The transmission. Eccentric shaft is the spindle of the crusher, which is bearing huge torsion and made by the high-carbon steel.
2. Rack. The frame is a rigid frame with upper and lower opening. It is the support of the eccentric shaft and bears the reaction of broken material.
3. Jaw plate and side guard board. Dynamic jaw and static jaw are all made up of jaw bed and jaw plate, jaw plate is the working part and fixed to the jaw bed with bolts and wedge iron.
4. The flywheel.The flywheel of jaw crusher is for store the banking energy of dynamic jaw to reuse in the formation of industrial and make the machinery work uniformly.
5. Lubrication device. Eccentric shaft bearing usually adopts concentration circulation lubrication. The support surface of the heart axis and the thrust plate generally feed oil by manual oil gun with grease.
6. Adjusting device. Adjusting device also called adjusting screw. The common adjusting device includes wedge type, subplate type and hydraulic type, and the wedge type is the general choose.
7. Reset spring. The operation of the dynamic jaw is driving with spring. Without the spring the dynamic jaw can't move and the machine won't work.

Application of Jaw Crusher
