Read MoreIn 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

Thus, during calculating the grinding balls mass in ball mill (after measuring the mill filling degree with grinding media) needs to use the grinding balls bulk weight whose diameter was determined earlier. In this case, it may be differ from the grinding balls bulk weight loaded to the mill. The formula for calculating the grinding balls mass in ball mill is given below (we will consider the

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

Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows: Example Calculation. A motor with

Circulating Load Calculation Formula. Previous Next. View Larger Image. Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over

2) Ball milling a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.

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 start to collide with each other and no milling will

Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be 21-24 % of the empty mill. Now, in order to get an efficient milling action, 80-110 % of the pores in

The geometry of a mill with conical ends is shown in Figure 8.6. The total volume inside the mill is given by Vm 4 D2 mL 1 2(Lc L) L 1 (Dt/Dm) 3 1 Dt/Dm (8.16) The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill

As a general rule the tow ball weight is around 10% of gross weight, i.e. if the van has a gross of 2.5 tone then tow ball would be around 250kg.. I stand corrected of course. If you have a problem you could always take the van to a public weighbridge then work out the 10%. If that all makes sense.
