The gyratory crushers crush to reduce 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.
Datasheets for Crushers. Industrial Crushers reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of ra. Crushers: Learn more.

· Secondary crushing, as you can imagine, is the second stage of material processing following its initial reduction. At this stage, material will flow through perhaps a second impactor or even a cone crusher, which is effective at breaking down these types of material. There are also tertiary and even quaternary stages of crushing that exist to ...
· INSIDE THE CRUSHER. The major wear part for a mobile crushing plant is the crusher itself. In a jaw crusher, the major wear parts are very limited – only a fixed jaw and a swing jaw, and two or four side or cheek plates. An impact crusher, on the other hand, has a lot more wear items.
The secondary crusher housing is a rugged, fabricated steel plate construction with heavy external bracing for increased strength. For quick and easy inspection . of the internal wear parts, the housing is fitted with large doors which are secured/ opened by a special dovetail locking mechanism. The rear housing section opens

The secondary crushers are designated as Standard cone crushers having stepped liners and tertiary Short Head cone crushers, which have smoother crushing faces and steeper cone angles of the breaking head. The approximate distance of the annular space at the discharge end designates the size of the cone crushers.
The first cone crusher was developed by the brothers to improve secondary and tertiary crushing applications. While jaw crushers provide excellent primary crushing duties, new ways of crushing needed to be devised for finer and more consistently sized aggregates. In 1920, the brothers created the first cone crusher.
· Secondary crushers use the same size bottom shells as certain size primary crushers, but different size top shells, mainshaft and spider assemblies. The 30-70 secondary gyratory crusher uses the bottom shell of the 42-65 primary crusher; the 24-60 secondary …
Cone crushers are fed with pre-screened material from the primary crusher (usually a jaw crusher or primary gyratory), and the secondary crusher should always, if possible, have a scalped feed. Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher.
