Introduction:Despite that the jaw crusher has been developed for many years, it is still widely used in fields of metallurgy, mining, chemical, construction, fireproof material, ceramics industry because of its simple structure, solidity, reliability, easy maintenance. It can be used to crush rocks with a fracture strength within 147-245MPa into coarse/medium/fine size. 
        In order to meet the requirement of high crushing ratio and hardness of low carbon ferrochrome in fields of metallurgy, mining and construction nowadays, we have designed modern Jaw crusher.

Features:1. All kinds of model available 2. Stable and reliable operation 3. High reduction ratio 4. Uniform-sized finished products 5. Easy to maintain 6. Low operating cost 7.Deep crushing chamber 8.Wide size range of discharging opening 9. The machine has a better performance with the hydraulic coupling.

Composition:It comprises the frame, the eccentric shaft, the grooved wheel, the flywheel, the mobile jaw, the side plate, the toggle plate, the captured spring, the fixed jaw plate and the mobile jaw plate, the safety device and the adjusting device, etc.

Working principle:The motor drives the belt and the grooved wheel, and then makes the jaw move up and down through the eccentric shaft. When the jaw moves upwards, the angle between the liner plate and the jaw becomes larger, which will push the mobile jaw plate close to the fixed jaw plate, during which the material is crushed. When the mobile jaw moves downwards, the angle between the liner plate and the mobile jaw becomes smaller. The mobile jaw plate will leave the fixed jaw plate under the force the rod. The crushed material will drop from the discharge opening. With the motor rotating continuously, mass production can be realized.
