- Ball Mill Specific Consumption

The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.

A feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages

between the ball-mill power draw values determined from the Denver slide rule, and those calculated from the proposed model. zFrom the distribution of the points around the line of comparison the good agreement of the results received is obvious. 0 200 400 600 Ball mill power draw predicted from the Denver slide rule, kW 0 200 400 600

A feature of ball mills is their high specific energy consumption a mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, i.e. during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantagesget price

SAG mills operation data abstract Comminution, particularly milling, is on average the largest consumer of energy in mining. Actual com-minution circuits consist in most of the cases in coarse crushing, SAG milling, pebble crushing and sec-ondary ball milling. In these circuits the SAG mill is the largest energy consumer. In many engineering

The Bond work index, W i, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.Therefore, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a given size of grinding product, the value of the work index W i ...
