Ball mills are used in many industries to grind coarse material into a finer powder. When it comes time to service the mill, an access hatch must be positioned to allow technicians to enter the mill and for the ball charge to be changed. That is when difficulty can begin. Positioning the access hatch is accomplished by a process known as spotting or inching. Without a dedicated inching system it can be difficult to precisely position the mill, since the technician has no way to accurately and ef

Pdf Evaluation Of Synchronous Motors On Grinding Mills

Traditional positioning technology applies a switched DC current to the stator windings in a specific pattern to simulate the sinusoidal AC wave form applied during normal operation while keeping the field excited. However, abruptly starting and stopping the motor can cause mechanical and electrical damage to the equipment. This, along with full voltage starting, stresses the overall electro-mechanical system and can cause excessive downtime and reduced production.
