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 ...

Grate Discharge mills will not face this issue. C) This value represents the Volumetric Fractional Filling of the Voids in between the balls by the retained slurry in the mill charge.

Since the variation of ball load volume in the operational mill varies from 11.5 (34 tonnes ball load) to 14.3 (42 tonnes ball load) the angular position of the maximum vibration point as a characteristic value of the fill level is superior to the traditional vibration feature values and can overcome the effects of the wear of ball load and

Ball mill level sensor. ball mill level control The filllevel measuring and control system for ball mill is introduced which is based on multi sensor information fusion technology The relationship between fill level and process parameter is researched based on the analysis of mechanical model.

Calculation of the filling degree the ball mill with grinding media For the ball mill efficient operation, it is necessary to constantly maintain the required loading level by the grinding media. It is very important to correctly and accurately measure the grinding media quantity in the mill.

Enter the width of a mill shell liner. Note this is not the width of a lifter! You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual RPM: Enter the measured mill rotation in revolutions per minute.

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a

More 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 ...

In order to achieve this improvement you permanently need to adjust the mill's feed. While keeping the fill level at the optimum, the grinding process becomes stable. A good operator, for example, takes care of the fill level and manually changes the fresh feed.

Nov 01, 2009· Since the variation of ball load volume in the operational mill varies from 11.5% (34 tonnes ball load) to 14.3% (42 tonnes ball load), the angular position of the maximum vibration point as a characteristic value of the fill level is superior to the traditional vibration feature values and can overcome the effects of the wear of ball load and ...
