convenient and safe. The crusher is easy to open, it has a very effective tramp-release system, and it clears the cavity efficiently. With the HP Series, you can rotate the bowl of the crusher open for easy liner changes using the hydraulic motor. The hydraulic motor also rotates the bowl to adjust the crusher setting.

eccentric bushing in the eccentric bearing (G) via the countershaft assembly (H). This rotating eccentric bushing imparts an eccentric motion to the main shaft (B), a characteristic of the gyratory crusher. In this way the crushing gap located between the fixed concaves in the crusher shell and the eccentrically gyrating mantle continu -
Productivity of the crusher can be improved upon by increasing the eccentricity of the eccentric shaft, use of reversible jaws, bush bearing and easily adjustable toggle plate. ... of 10:1 can be ...

the fixed concave liners mounted in the top shell of the crusher. The gap is opened and closed by an eccentric assembly in the bottom shell, which causes the central vertical shaft to gyrate. The vertical shaft is free to rotate about its own axis. Gyratory crushers are one of the main primary crusher types used in mines and quarries.
primary-crushed ore from a jaw crusher with greater flexibility (up to 25% larger material) because of its 1.3m (52-inch head) diameter, large feed opening, high-pivot-point crushing action, and wide crushing stroke. Outstanding gradation control and cubical product also make the R450 an excellent tertiary crusher

The eccentric assembly of a gyratory crusher is a key component that provides the gyrating motion of the crushing head and mantle. The eccentric assembly is located at the bottom of the crusher and is supported by the bottom shell assembly. The eccentric assembly typically consists of an eccentric shaft, a bronze bushing, and a bevel gear.
A gyratory crusher is a type of crusher that uses a mantle to guide the crushing process. The mantle is suspended on an eccentrically rotating shaft, which causes the mantle to gyrate. The gyratory crusher has a higher capacity than a jaw crusher. It is often used for primary crushing in the stone crushing industry.
