dual motor sag mills

Double squirrel cage motor

At starting of the motor, frequency of induced emf is high because of large slip (slip = frequency of rotor emf / supply frequency).Hence the reactance of inner cage (2 πfL where, f = frequency of rotor emf) will be very high, increasing its total impedance. Hence at starting most of the current flows through outer cage despite its large resistnace (as total impedance is lower than the inner Get price

TECHNICAL How to Spec a Mill Gear

mill, it needs to have a bore larger than the mill outside diameter. The mill out-side diameter is a function of the grind-ing process selected. Autogenous mills are the largest in diameter since the feed grinds itself. A semi-autogenous mill uses some metallic or ceramic balls to assist the grinding process and can be slightly smaller.
