involve grinding). With Lloyd's ball milling book having sold over 2000 copies there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research which was obtained from the commercial ball milling industry and explains some of the key design criteria for making your own ball mill.

#### Ball Mill Design/Power Calculation

If P is less than 80% passing 70 microns power consumption will be. Ball Mill Power Calculation Example. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work .

#### Calculate and Select Ball Mill Ball Size for Optimum Grinding

To accelerate the math or calculation you can use the shortened formula: D m <= Km * d^0.5where Km =6 (log dk) is taken from Figure 5 according to the fineness of the finished product dk. These formulas are applicable to the case of feeding a mill with only single-sized balls and not a mixture without consideration for ball wear.

#### Ball Mill Parameter Selection & Calculation - Power Critical .

The ball loading capacity of the mill can be calculated according to the formula (1-14). Gra — Quantity of Grinding Medium T. Rho s — loose density of grinding medium t/m3.
