Calculation of reduction ratio in crushing [image: (135-5-3)] Crushing Equipment The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant (e.g. blasting pattern and mining method) and others which are downstream of the crushing plant (e.g. mill and grinding circuit selection).
Why McLanahan Crushing Equipment. McLanahan crushing equipment accepts feeds of large material and reduces the material to the desired product size. Because each crusher type has a limited reduction capability, sometimes several stages of crushing are needed to achieve the desired final product size.
The term “secondary crushing” has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed. The term should not be used, as it sometimes is, to designate a particular type or size of crusher
