Jaw Crushers – A double toggle jaw crusher is large and can crush jagged rocks, glass, iron, and other heavy materials, while single toggle versions have less working parts – meaning less maintenance – and an extra up-and-down crushing motion (due to the positioning of the eccentric drive shaft) that is good for smaller jobs.
Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.

Using screens may also decrease the capacity required of one or more crushers, allowing for smaller, less expensive crushers in one or more stages of the circuit. All of the above methods of operation have been proven to reduce or minimize fines generation in coal crushing circuits.
Closed Circuit is defi ned as a combination of a crusher and one or more screens were all or parts of the material will pass the crusher. Over sized material will then be re-circulated to somewhere before the crusher and thereby fed to the crusher again to be re-crushed. Parts of the rock material will thereby pass the crusher more then once.
