Jaw crusher, primary crushing device of choice, with a crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics, it is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and many other sectors. Jaw crusher is the use of compression and bending two jaw plate materials, rough broken or broken in various hardness materials broken machinery. Its broken body from the fixed jaw plate and movable jaw plate, jaw plate close to the time when the two materials Jibei broken jaw when the two left the nesting population is less than a block of material discharged from the bottom. It's broken jaw crusher crushing operation is carried out intermittently. This crusher due to simple, reliable and can be broken advantages of hard materials are widely used in mineral processing, building materials, silicate and ceramics and other industrial sectors, and cone crusher compared to less investment jaw crusher finished stone tablets less double jaw crusher, low production costs. Compared with the hammer crusher, wear-resistant parts using a long time, high efficiency, small post-investment. Gyratory crusher cone crusher is the use of conical cavity in the housing cycle in the movement of materials have squeezed split and bending role in crushing a variety of large-scale crushing machinery hardness of ore or rock. Broken cone with the spindle bearing beams in the middle of the bush, which is placed in the lower end of the hollow shaft of the eccentric. Bushings rotation, broken cone machines around the center eccentric cycle exercise its crushing action is continuous, so the efficiency is higher than jaw crusher. By the early 1970s, large gyratory crusher has been able to handle material per hour, 5,000 tons, the largest feeding diameter up to 2000 mm. Gyratory crusher used in two ways to achieve nesting population adjustment and overload insurance: First, using mechanical means, top of their spindle nut adjustment Shandong jaw crusher, rotary adjusting nut, cone crusher can be lowered or raised, the exhaust spout becomes larger or smaller, overloading, cut off the drive pulley on the insurance sales to achieve the insurance; the second is the use of hydraulically hydraulic gyratory crusher jaw crusher, the shaft is located in the hydraulic cylinder plunger mining jaw crusher, the volume change under the plunger hydraulic oil can change the upper and lower cone crusher location, thus changing nesting population size. When overloaded, the spindle downward pressure, forcing the plunger into the hydraulic oil in the hydraulic system accumulator, broken cone ensuing decline to increased nesting mouth with material into the crushing chamber of non- broken material (iron, wood, etc.) in order to implement the insurance.
