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 of the new impact crusher, rotate adjusting nut, cone crusher can be lowered or raised, so that the discharge mouth 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 impact crusher, the shaft is located in the hydraulic cylinder plunger on a 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 major impact crusher, broken cone ensuing decline to increased nesting mouth with material from entering crushing chamber non-broken (iron, wood, etc.) in order to achieve insurance. Impact crusher impact short break Shandong impact crusher, a "stone at stone" crushing blow from works combined with the characteristics of the ore developed efficient gravel crusher equipment. HX series impact crusher is widely used in a variety of rock, abrasives, refractories, cement clinker, quartz, iron ore, concrete aggregate and other hard, brittle materials in the debris, fine (sand system). Construction sand, gravel roads used particularly appropriate. Fine break for a variety of ores, now replace hammer crusher, roll crusher, rod mill and other traditional equipment, sand making industry has become the mainstream equipment. The impact broke is an energy efficient sand gravel equipment, sand making energy saving than the traditional 50 percent, is the world's advanced sand making equipment at present.
