The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Ball-Rod Mills, based on 4″ liners and capacity varying as 2.6 power of mill diameter, on the 5′ size give 20 per cent increased capacity; on the 4′ size, 25 per cent; and on the 3′ size, 28 per cent. This fact should be carefully kept in mind when determining the capacity of a Steel- Head Ball-Rod Mill, as this unit can carry a greater ...

4/11/2017· The formula for calculating the grinding balls mass in ball mill. G – the grinding balls mass in ball mill, t; j – the mill filling degree with grinding balls, %; V – the mill volume, m3; g ш – the grinding balls bulk weight, t/m3. The correct determination of the grinding balls bulk weight in mill allows accurately determination the ...
The subsequent result or effects of overcharging is increased power consumption by the ball mills. 2.3 Increased Power Consumption Power consumption by ball mills is directly proportional to mill load/charge volume and specifically the amount of grinding media added at a particular time.
top point in the mill and load surface (H) [5-7]. This equation is profitable for determining of whole mill load volume which is included stony and metallic balls. Mill load (%) = 113.7 - 127.3 H Dm (1) where H is the height of top of the balls to under the mills liners (m), and D m is the mills diameter (m).
Ball Mill Loading (dry milling) When charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product. Charging a Dry Mill – The general operation of a grinding mill is to have the product impacted between the balls as ...

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or ...
