In all of the crusher equipment, jaw crusher were liked by customers.Because of the jaw crusher has simple structure, convenient maintenance, convenient usage, etc.So, what are components of jaw crusher?Jaw crusher structure is simple, mainly composed of frame, jaw plate/side guard plate, transmission parts, adjusting device, flywheel, lubrication device and so on five big parts.

1. The frame.Frame is used as a support eccentric shaft, and need to bear the counterforce of crushing material, material has sufficient strength and rigidity.
2. The jaw plate and side plate.Mostly it's made of cast steel or cast iron pieces such as material.
3. The transmission parts.Eccentric shaft is the centerpiece of crusher, there is a huge bending torque, manufactured high carbon steel.
4. Adjusting device.Adjusting device of wedge type, plate type and hydraulic type, etc.The discharging mouth regulation of small jaw crusher is use gaskets to increase or decrease.
5. The flywheel.Dynamic jaw jaw crusher of the flywheel to store energy in air travel, and then used in industry to form, the mechanical work tend to be more uniform.
6. The lubrication device.The eccentric shaft usually adopt centralized circulation lubrication way.Spindle bearing surface and thrust plate generally adopt manual oil gun.
