Factors that May Affect the Work of Jaw Crusher

What are the main factors affecting the jaw crusher main factors affecting the work of jaw crusher work there have nip angle and the number of revolutions and so on.

Jaw crusher is the most widely used international crusher, detailed crushing ratio, average particle size , simple structure , facilitate maintenance and other advantages , sub- coarse and fine broken two kinds. Maximum compressive strength of the material to be broken as 320MPa. Its pioneering medium-sized jaw crusher is one of my company's products , particularly in the design and production of large jaw crusher , the absolute leader in the country has been in the level .

Nip angle is the angle between the jaw and the fixed jaw moving between , according to the calculations, the maximum nip angle up to 32 °, and the actual use is less than 25 °, usually about 18 ° -20 °, nip angle is too large, will ore crushing cavity upward extrusion, resulting in injuries or damage to other equipment , and follow the nip angle increases ( broken than increase ) , production rate. Adjust the size of discharge products , also change the size of nip angle . In actual production , according to the granularity of discharge requirements to adjust the size of discharge port . Therefore , to ensure the product size requirements , the day the port of discharge amplification is fair. Pai mine mouth size can be adjusted by adjusting the block , when adjusting the size of the port of discharge to pay attention to the broken relationship between the ratio and the production rate .

In fact in a range of number of revolutions of the eccentric shaft can improve the production capacity of the crusher , crushing but also the power consumption per unit mass of ore . Speed ​​too , would have been crushed in the crushing chamber ore time to discharge and clogging phenomenon , but to make to reduce production capacity , power consumption increases. Therefore , jaw crusher should be one of the most affordable revolutions .

Jaw crusher eccentric shaft , the connecting rod, movable jaw plate , lining the main shaft and wear parts , often need to pay attention to lubrication and replacement.

At the present, Fote Heavy Machinery has set up three state level machinery research institutes, and we also produce various kinds of tertiary impact crusher in china, mobile jaw plant and free service for assembling various kinds of production line.
