Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap between the bowl liner and the mantle narrows, the rock is crushed …
They use compression force to break the rock between the gyrating spindle and the enclosing bowl liner. The rock becomes wedged and squeezed as it enters the top of this rock crushing equipment. The cone crusher breaks large pieces of ore once into smaller particles that fall to a lower position where they are broken again. ... Impact …
Using Dynamic Models Gyratory and cone crushers (gyracone crushers) are widely used in the mining and aggregates industry.

Gyratory crushers are principally used in surface-crushing plants. The gyratory crusher (Figure 6.5) consists essentially of a long spindle, carrying a hard steel conical grinding …
The cone crusher is a modified gyratory crusher, and accordingly many of the same terms including gape, set, and throw, apply. ... but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory crushers. Figure 5.3 is a schematic diagram of a cone crusher.
GY primary gyratory crusher can be started under full load should it be required; e.g., in the case of an unplanned power failure. The spider arms are an integral part of the spider assembly. The spider assembly, which is a one-piece casting, is specifically
The feed material is usually fed to the crusher through a feeding tube, where it is then crushed by the gyrating mantle. The crushed material then exits the crusher through the bottom of the machine.
Cone and gyratory crushers – Cone and gyratory crushers are gyrating shaft machines. They have a main shaft that gyrates and provides the crushing motion. Crushing takes place between a fixed outer crusher member (the concave ring) and a moving inner crushing member (the mantle), mounted on the gyrating shaft assembly.
They feature a conical head gyrating within a stationary bowl, providing a large feed opening and high capacity. Gyratory crushers are often preferred for their ability to handle abrasive materials. ... Safety precautions when operating a rock crusher include wearing appropriate personal protective equipment (PPE), following the manufacturer's ...

Gyratory Crusher - Mining Fundamentals. A gyratory crusher is an ore processing machine that crushes the ore between an eccentrically mounted cone and a crushing throat, that …
Each type of stone crusher has a unique design and purpose, from jaw crushers to cone crushers, impact crushers to hammer crushers. Understanding how each type works is essential to making informed decisions about which to use in different situations. ... They operate by squeezing the material between an eccentrically gyrating spindle and a ...
The working principle of primary crushers varies depending on the type of crusher, but generally, they work by reducing the size of the material through compression or impact. In jaw crushers, the material is fed into the crushing chamber and is crushed between a fixed jaw and a movable jaw. Gyratory crushers work by crushing materials …
A measure of the size reduction achieved for a particular crusher application is the reduction ratio. A cone crusher in a secondary crushing application will typically work with a 3.5:1 to 5:1 reduction ratio. Tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1.
A gyratory crusher receives ore from a mine and crushes the ore between a gyrating main shaft and stationary liners called concaves. This module explains the gyratory crusher's principle of operation and provides detailed descriptions of the major components and the role that each component plays in its operation. You'll learn how the drive ...
