Milling Crushing typically takes Run-of-Mine ROM ore down to particle sizes ranging from 6mm to 25mm depending on the type of processes to follow. Crushed ore is fed into Mills in which the ore is mixed with water and may be ground down to a particle size in the case of gold and copper of about 75 microns 0.075mm.

Calculate The Reduction Ratio And The Number Of Milling

Calculate The Reduction Ratio And The Number Of Milling

Mar 28 2021 How to determine the number of milling stages using reduction ratio. 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 R1 into smaller ratios thus it refers to multiple units of size reduction. The milling work is done in two circuits crushing and .

Abstract A run-of-mine ROM ore milling circuit poses many difficulties in terms of measuring process variables and determining accurate models. Control of the ROM circuit is therefore not a trivial task to achieve. An example of a ROM circuit model with reduced complexity that works well for control purposes is discussed. The mill model is discussed in detail as this model is used for state .
