The basic difference between a gyratory and jaw crushers are: At the same feed size rocks, the capacity of a gyratory crusher is much greater than that of a jaw crusher. A gyratory crusher in a primary duty install will usually cost more VS a similar jaw construction set-up.
The three main types of primary crushers are jaw crushers, gyratory crushers, and hammer crushers. Jaw Crusher. Jaw crushers use the compressive and …
In general, primary crushing in mining is best conducted with gyratory crushers, jaw crushers or the eccentric roll crusher whereas the later crushing stages are the operation areas of cone crushers. Of course, our thyssenkrupp Crusher experts will happily help you to define the best crusher solution for your operations.
Jaw crusher feed should be pre-screened using a grizzly prior to crushing to remove any material finer than the closed-side setting. Cone and gyratory crushers. Cone crushers and gyratory crushers are also compression-type machines that crush material between a moving piece of steel and a stationary piece.
With an enlarged feed opening, the Jaw Gyratory Crusher Pro is the ideal solution for underground and block cave mining applications. No material too coarse, no chunks too …
Engineered to outperform - is a leading developer of heavy-duty crusher wear parts for all major makes and models of cone, jaw and gyratory crushers.
What is the difference between a jaw crusher and a gyratory crusher? A jaw crusher operates by compressing materials between two plates. A gyratory crusher, on the other hand, operates by means of a gyrating mantle against a stationary concave surface. What are the advantages of using a cone crusher?
There are several types of rock crushers, each with its unique mechanism and use. The most common types include jaw crushers, cone crushers, impact …
Jaw crusher and gyratory crusher process granite (with videos) Granite one of the stones that is hard, abrasive and with high compressive strength, and it needs jaw crusher or gyratory crusher to make a primary process.

For instance jaw or gyratory crushers in primary crushing and cone crushers in secondary crushing. Primary crushing is for the robust. The very first crushers invented were jaw crushers, which are built to reduce the size of large materials and operate with high volume in primary crushing.
Working Principle of Crushers. On left is a showing of the "standard gyratory with straight concaves" is a section through any vertical, radial plane in the crushing chamber of one of the intermediate sizes of the crusher. In order to understand the crushing action in such a chamber it is helpful to consider the process as though each step took place in …
Up to this time the jaw crusher had kept pace with the gyratory, both from the standpoint of receiving opening and capacity, but now the gyratory stepped into the leading position, which it held for some 15 years.
In the standard gyratory crusher this is accomplished very simply by increasing the thickness of the concaves at the top, and tapering them down toward the discharge; in the jaw crusher the change is generally made by inserting a wedge-shaped filler behind the liner plates on the movable jaw.
At the time these early gyratory crushers were developed all mining and quarrying, either underground or open pit, was done by hand; tonnages generally were small and product specifications ... jaw and gyratory crushers. Manufacturers redesigned their gyratories to reduce the feed opening, decrease the closed-side setting, and in-
