Gyratory crushers are frequently used in the primary crushing stage and a little less often in in the secondary stage. Gyratory crushers have an oscillating shaft. The material is reduced in acrushing cavity, between anexternal fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly.

The gyratory crushers crush toreduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 8:1.

Gyratory and double toggle jaw crushers using this method of compression are suitable for reducing extremely hard and abrasive rock However, single toggle jaw crushers employ attrition as well as compression and are less suitable for abrasive rock since the rubbing action accentuates the wear on crushing surfaces.
These new improvements to the Metso Superior™ MKIII primary gyratory crushers brings up to70% reduction in downtime. Crusher maintenance downtime has also produced a significant size decrease of the primary stock pile as well.

Gyratory Crushers Material is fed through a feed plate that distributes the particles evenly into the chamber between the mantle and the concave casing. The mantle oscillates, causing a decrease in the volume between the mantle and the concave casing and crushing the material. The crushed material then exits freely from the apparatus.
May 13, 2019· Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus …

A ConeCrusheris a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing andreductionis determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the ...

Primary crushers are characterized by the maximum size of boulders that they can accept and secondary crushers are defined by their reduction ratio. The reduction ratio R is defined by: R = feed size product size at outlet This ratio ranges from 4 to 8 and is moderate, which explains the low energy consumption per unit mass of product.
GC gyratory crusher GC series Gyratory crusher is used as primary crushing of various rocks, features as follows: large capacity, high crushing efficiency, larger reduction ratio, consistent product size, lower consumption, etc, fit for the application of larger capacity. When OSS at 150mm, the pass through rate is 90% while crushing soft rock.
Jaw crushers and gyratory crushers are used as Primary crushers in two stage crushing. Size reduction ratio is limited to 5 to 6: I. Hammer crushers and Impactors can be used both as Primary crusher in single stage crushing and as Secondary crusher in two stage crushing operation.
Gyratory crushers feature a conical head and concave surface (often lined with manganese steel) and break apart material by compression through what is known as eccentric movement. Like jaw crushers, gyratory crushers are often utilized in primary crushing stations, though they may sometimes be used as secondary crushers, as well.
