The crushing plant product is controlled by the screens between the Standard and Short Head crushers and the closed side setting of the Short Head crushers. With this design it is a requirement to maintain a 6MM to 10MM (¼" to 3/8″) setting to produce a mill feed that is nominally minus 19MM (¾").

The target product size required from the crushing circuit will determine the number of crushing stages and types of crushers to be used for a specific application. E.g.. To produce a coarse product a single stage crusher may be required. To produce a 15 mm product a two stage crushing may be required.

The same applies to many mobile crushing units. As the number of crushing stages is normally small with this type of plant, it is almost impossible to obtain a good product shape unless the rock is relatively soft and thus more suited for the production of cubic product. A centrifugal crusher in the final stage can help to solve the problem.

Depending on the feed size and desired final grain size, it may be necessary to install three crushing stages. If a grain size of < 30 mm is desired, the feed size of the primary crusher with two-stage reduction is limited to 500 to 600 mm. Of course, this limitation applies only to the hard rock inclusions.

Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

Primary crushers reduce large run-of-mine material, such as rocks and ore lumps, into smaller sizes for further processing downstream, whether that be transport to additional crushers or to a wet processing plant. It is the first stage in the crushing process that can sometimes include secondary, tertiary and even quaternary crushing …
