Detail:Affect jaw crusher The main factors nip angle and the number of revolutions and so on. Nip angle is between the movable jaw and fixed jaw angle. According to calculate the maximum nip angle up to 32 degrees.
Jaw crusher is the crushing equipment appeared earlier, because of its simple structure, rugged, reliable, easy maintenance and repair as well as production and construction costs less, therefore, has still widely in metallurgy, chemical industry, building materials, electricity, transportation and other industrial sectors, for compressive strength at 147 ~ 245MPa crushing all kinds of ores and rocks of coarse, medium and fine. In recent years, I plant to meet the metallurgical, mining, construction and other industrial sectors crushing high strength, high hardness, low carbon ferrochrome needs, specially developed strong jaw crusher.
Use: jaw crusher is mainly used for a variety of ores and medium-grained bulk materials crushing, is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry. The maximum compressive strength of the material to be broken as 320MPa.
Features: crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, low operating costs. Working principle: work, the motor drives the eccentric shaft through the pulley rotates to move the jaw cycle close, leaving the fixed jaw, and thus materials are squeezed, rubbing, grinding, such as multiple broken, so that the material into small, gradually fall until discharged from the discharge port.
Affect jaw crusher The main factors nip angle and the number of revolutions and so on. Nip angle is between the movable jaw and fixed jaw angle. According to calculate the maximum nip angle up to 32 degrees. The actual use are less than 25 degrees, typically 18-20 degrees. Nie angle too, will make up the ore crushing cavity extrusion, resulting in injuries or damage to other equipment, and with the nip angle increases (crushing ratio increase) decrease in productivity. Adjust the size of the port of discharge, also change the size of nip angle.
In practical applications, according to the size of discharge requirements to regulate the discharge mouth size. Therefore, to ensure product size requirements, as far as the port of discharge amplification is reasonable. Pai mine mouth size can be adjusted by adjusting the block, in the regulation of the size of the port of discharge to the attention of crushing ratio and the relationship between productivity.
In a certain range, the number of revolutions of the eccentric shaft increases, can improve the production capacity of the crusher, crushing unit weight but also increases the power consumption of the ore. Speed ??too, would have been crushed in the crushing chamber ore time to discharge, and the clogging phenomenon, but to make the production capacity reduction, power consumption increases, so should a jaw crusher optimum rpm. Jaw crusher eccentric shaft, connecting rod, movable jaw plate, is the main shaft and liner wear parts, lubrication and replacement needs constant attention.
