Alternatives that provide sound mineral processing routes provide on-line mill control and are markedly cheaper to operate are presented as a potentially more viable and sensible route for both.
Apr 28 2012 tube mill similar to ball mill however length to the diameter is usually 3 or 4 : 1 as compared with 1 or 1The mill is filled with pebbles the characteristics of the two mills are similar but material remains longer in the tube mill because of its greater length and a finer product is therefore obtained.
Ball mills characteristic of the mineral processing industry are used to reduce ore from one size distribution to anotherWear is associated with comminution mechanisms found in the ball charge.

Dec 18 2013 fine grinding to p80 sizes as low as 7 μm is becoming increasingly important as mines treat ores with smaller liberation sizesThis grinding is typically done using stirred mills such as the isamill or stirred media detritorWhile fine grinding consumes less energy than primary grinding it can still account for a substantial part of a mill’s energy budget.
