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).

If you find the crusher operating in a crushing force over-load condition (ring movement) or a power over-load condition (excessive power), open the crusher setting slightly, but try to stay choke fed. The benefit of staying choke fed is that there will still be rock-on-rock crushing and grinding taking place in the crushing cavity.
