The gyratory crusher has capacities starting from 1200 to above 5000 t/h. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Therefore, primary gyratories require quite a massive foundation. The cone crusher is a modified gyratory crusher.

Inside the jaw box of a jaw crusher Gyratory crushers. Gyratory crushers can be used for both primary and secondary crushing. They are similar to cone crushers as they both have cone-shaped rotating shafts. The spinning shaft is used to crush the material against the wall of the crusher. Reduction ratio = 8:1.

Primary Jaw Crushers. How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone …

These machines come in three main types, jaw crusher, cone and gyratory crusher, and impact crusher. Jaw crushers, occasionally referred to as "toggle crushers," are the most common type of crusher. Material is compressed between a moving piece of steel and a stationary piece. Cone crushers are compression crushers that use a …

The largest gyratory crushers in current use attain throughputs of over 6000t/hour and have feed openings 1500mm x 4400mm in size (A x B), while the discharge graps range in width from 150 to 250mm. A jaw crusher designed for a certain throughput rate can accept larger pieces of rock than the normal gyratory crusher.

Impact crushers use hammers to crush the material while jaw crushers utilize two crushing jaws. Overall, impact crushers are better with hard materials while jaw crushers are better suited for more brittle materials. Impact crushers are also better at processing larger pieces of material while jaw crushers are more efficient at crushing …

Primary Crusher. There are several primary crushers, including jaw crushers, gyratory crushers, roll crushers, etc. The right one for primary crushing often depends on the material to be crushed, but the reduction ratio of jaw crushers are usually between 8:1 and 6:1. Secondary Crusher. These crushers break down materials into smaller sizes and ...

The main types are jaw crushers, gyratory crushers, smooth-roll crushers, and toothed-roll crushers. The first three operate by compression and can break large lumps of very hard materials, as in the primary and secondary reduction of rocks and ores. Toothed-roll crushers tear the feed apart as well as crushing it; they handle softer …
