- Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):-Modification of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency:

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The

For overflow ball mills, the charge should not exceed 45 of the mill volume . for grate discharge mills, the charge should occupy about 50 of the mill volume . bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, he, and the radius of the mill, r, i.e.,

Calculate Ball Mill Grinding Capacity. A) Total Apparent Volumetric Charge Filling including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume (inside liners).

Volume Calculation For Ball Mill. 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 ...

How a grate discharge ball mill works how a grate discharge ball mill works a grate assembly at the discharge en d of the mill permits retention of a higher ball charge up to 50 than is possible in an overflow mill which has a practical limit of around 4,Calculate Charge Volume In Ball Mill.

in these computations mill volume and total mill internal load, Equation 2, during the test have been calculated as 297.96 m3 and 19.55%, respectively. Mill internal load volume (m3) = (19.55*297.96)/100 = 58.52 m3 (2) Ball volume in total mill load could compute by Equation 3. Mill Ball (%) = 100{[(ball volume …

Add to this another 10%-15% above the ball charge for total of 23% to 25% product loading. So as a rule of thumb we use 25% solid loading. Empirical Check: Once the mill has been loaded and run for a few minutes, open the cover and look down into the mill. You should see some discernible layer of product on top of the media.

The aim of the present study was to optimise operating parameters (i.e. charge volume, make–up ball size regime, slurry mean residence time, number of hydrocyclones in operation and hydrocyclone ...
