Many instructables refer to United Nuclear Ball Mills. Their small ball mill cost between 70 and 80 dollars. Their small ball mill cost between 70 and 80 dollars. For no more than 30 and in 5 minute you can build a ball mill of appreciable performance.
SAG mill ball charge determination and its influence on mill drive requirements Abstract: In semiautogenous grinding (SAG), the grinding mill inventory, ( volume of total charge, volume of ball charge, etc.) is important in determining the optimum operating condition for maximum production (tph), minimum specific energy (kwh/t) or lowest ...
For the same amount of ball charge, the number of balls in the mill decreases as the ball size increases. Thus, the S values are lower for larger balls. However, larger balls are capable of breaking large particles; therefore, the size at which the S value becomes maximum, x m, .
