ball mill motors and protection

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight. Wound rotor motors are an extremely versatile breed of induction motors. Featuring a rugged design, these machines provide the unique ability to gradually bring up to speed high-inertia equipment and large loads smoothly and easily. Wound rotor motors also can develop high starting torque at standstill - while maintaining low inrush. Long
