The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotat- ing direction is helpful if too much sample material has been fed to the crusher causing it to block.

Depending on the size reduction required, the primary jaw crushers are followed by secondary and tertiary crushing. The last crusher in the line of operation operates in a closed circuit. That is, the crushed product is screened and the oversize is returned to the crusher for further size reduction, while the undersize is accepted as the product.

Compression crushers are used to break rocks and coarse particles larger than 3 cm in diameter. There are three main types of compression crushers: jaw crushers, gyratory crushers, and rolls. Equipment Design Jaw Crushers. Jaw crushers consist of a rectangular frame with a fixed jaw plate and a jaw stock carrying the moving jaw.

used crushers are of three types namely Cone crusher, Jaw crusher and Impact crusher. The first stage of size reduction of hard and large lumps of run-of-mine (ROM) ore is to crush and reduce their size. Large scale crushing operations are generally performed by mechanically operated equipment like jaw crushers, gyratory crusher and roll crushers.
