The first step in the mining and processing of nearly any mineral ore is comminution. Since the oil embargo of 1979, the mining companies have been striving to reduce energy consumption and costs. The first serious step was the introduction of in-pit crushing in the early 1980s. With in-pit crushing accepted as a standard design mode, the energy saving emphasis turned to …

Primary crushers can handle large feed lump sizes and typically include Jaw Crushers and Gyratory Crushers, but Impact Crushers may also be used as primary crushers if the material is easily crushed and not abrasive. After the primary crushing stage, further stages of crushing may be required to better control the size of the output and/or ...

Cone crushers resemble gyratory crushers from the technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed.

A stone crushing plant needs essential primary crushers like jaw and gyratory crushers as well as fine-crushing equipment like impact crushers and ball mills.
