Introduction

Gyratory crusher also can be called gyratory breaker and gyratory crushing machine. Gyratory crusher is large crushing machine for primary crushing of all kinds of ore or rock. The upper end of main spindle with crushing cone is installed in the middle of the bush, and its lower end is placed in the hole of eccentric sleeve. When the sleeve rotates, crushing cone does rotating movement around the machine centerline, and its crushing action is carried out continuously, so the working efficiency of gyratory breaker is higher than that of jaw crusher. By the early 70s, the processing capacity of large gyratory crushing machine was up to 5,000 t/h, and the maximum feeding diameter was 2,000 mm.

Gyratory Crusher

Features

① Non-clogging type crushing chamber, fluid discharging. The clogging-point is moved up after the optimization design of the crushing chamber, which improves the ore passing ability in unit time, reduces lining wear, increases service life, and saves energy.
② Reasonable eccentric bearings. The eccentric bearing of the gyratory crusher is made of high lead bronze, so it’s suitable for low speed and heavy load, and can improve the life of eccentric. Meanwhile, replacing the inner bushing can adjust the eccentricity of the gyratory crusher, to make it conform to production needs.
③ Reasonable gear installation. The eccentric gear of the machine is installed at the lower place, which provides gear good lubrication conditions, and extends service life of gears. On the other hand, the reasonable gear installation can reduce the height of rack, increase the stability of the crusher, and reduce its overall weight.
④ Direct transmission. Domestic crushers are indirect transmission, the motor drives the eccentric sleeve through the belt pulley.
