The jaw crusher consists of two jaw plates, the moving jaw and the static jaw, forming a crushing chamber, which simulates the movement of the two jaws of an animal to complete the material crushing operation. It is widely used in the medium-sized crushing of various ores and bulk materials in industries such as mining, smelting, building materials, roads, railways, water conservancy and chemicals.

Features of the jaw crusher:

1. The crushing chamber adopts a symmetrical "V" shape structure to make the actual feed opening width consistent with the nominal feed opening width.

2. The discharge opening adjustment is faster and more convenient. The European version of the JC series jaw crusher is equipped with a wedge block discharge opening adjustment device, which is simpler, safer and faster than the old-fashioned gasket adjustment.

3. The bearing specifications are larger and the load capacity is higher. All JC series jaw crushers are equipped with larger and more durable eccentric shaft bearings than other crushers of the same specifications. Their higher load capacity and effective labyrinth seal greatly extend the service life of the bearings.

4. The latest toothed guard plate is used to increase the effective length of the jaw plate and increase the output.

The preparations before starting the jaw crusher (jaw crusher) are as follows:

1. Carefully check whether the bearing is well lubricated and whether there is enough grease at the elbow plate connection inside the bearing.

2. Carefully check whether all fasteners are fully tightened.

3. Check whether the protective device is in good condition. If any unsafe phenomenon is found, it should be eliminated immediately.

4. Check whether there is ore or other debris in the crushing chamber. If there is, it should be eliminated immediately.

Therefore, the jaw crusher plays a great role in crushing ore.
