The main factors affecting the jaw crusher which under normal circumstances affect the main factors of the jaw crusher nip angle and the number of revolutions.Nip angle is moving Hubei and the angle between the fixed jaw. According to the calculation of the maximum nip angle up to 32 degrees. The actual use are less than 25 degrees, typically about 18-20 degrees. Nip angle is too large, make up the ore crushing cavity extrusion, resulting in injuries or damage to other equipment, at the same time as the nip angle increases (broken than increase) decrease in productivity. Adjust the size of the port of discharge, and also change the size of the nip angle. In real life, according to the row of ore particle size to adjust the size of the discharge mouth. Therefore, to ensure that the product size requirements, try to Pai mine mouth amplification is reasonable. Pai mine mouth size can be adjusted by adjusting the block to adjust the size of the port of discharge, pay attention to the broken relationship between the ratio and productivity.
Within a certain range, an increase of the number of revolutions of the eccentric shaft, the production capacity of the crusher machine can be improved, but also increases the power consumption of the crusher unit weight of ore. Speed too much, too late to make the crushing chamber has been broken ore discharge arising from clogging, but the production capacity to reduce power consumption, therefore, should be one of the most suitable number of revolutions jaw crusher.
Jaw crusher eccentric shafts, connecting rods, movable jaw plate, shaft and liner wear parts, lubrication and replacement needs constant attention.
