Calculate the Reduction Ratio and the Number of Milling ...

Mar 28, 2021  Generally, we need a very high reduction ratio to go from the run of mine to the liberation size. Therefore, it is necessary to divide the total R:1 into smaller ratios, thus it refers to multiple units of size reduction. The milling work is done in two circuits, crushing and grinding. The grinding reduction ratio is very higher than the crushing.

Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
