The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

Live ChatThere are two methods for determining the grinding balls bulk weight in a mill: Method with complete grinding media discharge from the mill inner drum. Method without unloading grinding balls.

Live Chatweighed. The total weight obtained after sieving is compared to the initial weight of the sample to calculate any material loss. The selection of the sieves that are compatible with the estimated size range of the sample is done according to the chart developed by geologists, given in figure 3. Figure 2. Schematic of the sieve analysis

Live ChatIn Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize just in case. Well, this safety factor can cost you much in recovery and/or mill liner wear and

Live ChatThe maximum power draw in ball mill is when ball bed is 3540 % by volume in whole empty mill volume. Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be

Live ChatSince the weight of pebbles per unit volume is 3555% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower.

Live ChatMore balls with small size results in fine powder. As a thumb rule powder to be milled should be taken as 25% of total ball weight. If the quantity of charge is very less then milling balls will
