17 Signs of Problems with Ball Mills: Quickly Remove Hidden Troubles

High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.Promising results obtained from cement industry encouraged the test studies on mineral grinding. van Drunick et al. (2010) presented VRM pilot plant test results where zinc ore was ground. In his study it was concluded that the total specific energy of the AG/SAG-ball mill circuit, which was 20.11 kWh/t, was reduced to 11.40 kWh/t by using Copper ore grinding in a mobile vertical roller mill pilot plant
