Description

Jaw crusher applies to the various minerals or rocks with strongest anti-crush pressure less than 250 Mpa.

Jaw stone crusher is widely used in mining industry, cement industry and concrete industry. Crushermainly used for first step crushing or the Middle Intermediate crusher.

Principle

The working parts of jaw crusher are two jaw plate, one is static (fixed jaw), it is vertically (or slightly lean outside) fixed on the front wall of the body, the other is the dynamic (moving jaw), it is in a tilt position and forms a small crushing chamber (working chamber) with the fixed jaw plate. 

The movable jaw plates are periodically reciprocated against the fixed jaws, sometimes separated and sometimes close. When it is separated, the material enters the crushing chamber and then the product is discharged from the lower part. When it is near, the material between the two jaws is crushed by crushing, bending and splitting.

Advantage

1) Stone Jaw crusher using world-class manufacturing process, moving jaw assembly using high-quality cast steel components, heavy eccentric shaft with forging processing.

2) Jaw crushing machine using the finite element analysis technique, the integral cast steel housing ensures complete cooperation with the frame, greatly enhancing the radial strength of the bearing, so that the device has a higher strength.

3) Jaw Crusher cavity with symmetrical "V"-shaped structure and discharger with wedge adjustment device make the adjustment simpler, safer and quicker.

4) Larger and more durable eccentric shaft bearings and toothed panels make the equipment carrying capacity stronger. So its yield is higher, working life is longer.

FAQ

A1. In order to ensure the normal operation of the jaw crusher, in addition to correct operation, you must have plan for maintenance, including Minor repairs,Moderate maintenance,Overhaul

Q2. What is the normal protection for the jaw stone crusher?
A2.Closing and checking jaw crusher periodically, regularly check the driving belt of jaw crusher and lubrication of mechanical parts.

Q3. What is the temperature request when jaw crusher machine working?
A3. The temperature of bearing should not exceed 30 ℃, the maximum temperature shall not exceed 70 ℃.

Q4. Things need attention when use the jaw crushing machine? 
A4. Turn off the power in time then check the reason, if the crusher stops working suddenly.

Q5. What is the different between the Minor repairs,Moderate maintenance and Overhaul？
A5. The repair cycle for minor repair is1-3 months, Moderate repair is 1- 2 years, the over haul cycle is 5 years per time.

Q6. How to protection the jaw crusher machine?

A6. In order to ensure the jaw crusher’s normal work, except the correct operation, it must be planned maintenance, including routine maintenance ,minor repair, repair and overhaul.
