Calculation of Grinding Balls Surface Area and Volume Quite often there is a need for a quick and correct calculation of a grinding ball surface area and volumeNecessity of such calculations may arise when choosing a container for reloading grinding media into a ball mill;when selecting the optimum characteristics of grinding ballsto suit
• Ball surface wear rate is approximately constant but with variations due to hardness and other factors Consumption is closely related to total ball charge surface area • A useful guideline for make up ball size for a new circuit was provided by Bond 1958 B = F80/K x [ WI x SG / Cs x ]1/3 3 In the historical British units B Recommended make up ball size inches F80
Grinding media are the means used to crush or grind material in a mill Browse our wide selection of grinding media at benefit of the pebble is the aspect ratio thus giving it a lot of surface area for contact in the mill They are still available but getting to be expensive A good alternative is Steatite Density gm/cc Bulk Density kg/l; #/l;
The two grinding media have different surface area bulk density and contact mechanisms in grinding action Comparative tests were conducted using the two types of grinding media in a laboratory Bond ball mill at various conditions of equality such as media mass size distribution surface area and input specific energy
Therefore for a given ball mill with a constant wear law the resultant seasoned 76 mm martensitic ball chart should contain more large balls fewer small balls and less surface area than a seasoned charge of 76 mm pearlitic carbon steel balls The reduced number of small balls combined with a lower ball charge surface area might explain the 6% lower grinding efficiency of a 76 mm
