01/12/2018 · The separation results for different cable sizes and various ball milling times with 20 mm balls are shown in Fig. 6(b) (Entries 13–15 in Table 2). The R sep values for the three types of cables followed a similar increasing trend, while the value for the mm diameter cables was slightly higher than for the others.
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,,

18/11/2008 · Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding.
Ball mills are the classic grinding plants: Around the world they are the most common installations. Ball mills convince thanks to their simple principle and low maintenance needs: They are robust, durable and extremely reliable in operation. By using ball mills in closed circuit with a separator, their efficiency can be increased even further.
