Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.

Contact UsThis is why a re-torque is specified and is usually carried out, (mostly seen on liner bolts), but what about the bolts holding the mill together?, All to often they are just overlooked, and the results can be seen above.When the mill finally goes into operation the structural bolts on mills are exposed to extreme loads during operation and after a period of time they start to relax and loosen ...
Contact UsA typical relationship of motor power/torque output, M1, with mill speed is illustrated for a nominal (or rated) motor speed equivalent to 72% CS. Examples of the power requirement developed by a mill charge as mill speed increases have been added for a 10% v/v ball charge at different total mill charge volumes ranging from 15-30% v/v.

Contact UsSquirrel cage motors are the most commonly used induction motors, but the main drawback in them is their poor starting torque due to low rotor resistance. (Starting torque is directly proportional to the rotor resistance).But increasing the rotor resistance for improving starting torque is not advisory as it will reduce the efficiency of the motor (due to more copper loss).
