Jaw crusher is usually used in the entire production line for the first time crushing, if there is a problem will affect the entire production line can not work, but if unable to master the method of operation, will often cause crashes jaw broken, so during our broken material we should note that even cutting, but also pay attention to the hardness of the material, if perfect, then it needs to be further processed.
The main factors affecting the general jaw crusher work are nip angle and number of revolutions. Dynamic nip angle is the angle between the jaw and the fixed jaw. According to calculate the maximum nip angle up to 32 degrees. The actual use are less than 25 degrees, usually about 18-20 degrees. Nip angle is too large, it will make up the ore crushing cavity extrusion, resulting in injury or damage to other equipment, and with the nip angle increases (broken than increase) decrease in productivity. Adjust the size of discharge port, it changes the size of the nip angle.
In real life, according to the row of ore particle size requirements to adjust the size of discharge opening. Therefore, to ensure product granularity request, try to enlarge the port of discharge is reasonable.
Jaw crusher eccentric shaft, rod, movable jaw plate, shaft and liner wear are the main components, lubrication and replacement needs constant attention. Through the above description of the jaw crusher freezes, we can clearly know Jaw Crusher, if you encounter a problem, we can use the above method of investigation.
