3 Common Problems and Solutions in Ball Mill Operation Miningpedia
Reason #2：The supplement of steel balls is insufficient. Due to the longterm operation of ball mill, the steel balls will wear violently, the diameter will be reduced, and the impact force will be correspondingly weakened. When the steel balls in the ball mill are not replenished in time, the processing capacity of the ball mill will be reduced.

A very basic overview, but the advantage of wound rotor slip ring motor is that, through a LRS u can vary the resistance of the rotor. The advantages are 1. able to manipulate the torque speed curve, allowing u start with a much higher torque. Wound motors are suitable for application with heavy starting duties such as ball/sag mills, crushers etc.
Ball Mill (Ball Mills Explained) saVRee saVRee
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

Operating principle of Vapromatic type LRS This is based on the difference in resistivity between a liquid electrolyte and its vapour, contained in an electrode chamber. The passage of the initial rotor current causes immediate partial vaporization of the electrolyte and instantaneously adjusts resistance and starting torque to optimum values.
