An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically ...
synchronous motor driven ball mill. The Benshaw variable frequency drive powers the 4160 volt - 3500HP synchronous ball mill motor during positioning to smoothly rotate the ball mill and bring it to the proper position for maintenance. The customer's previous system utilized multiple DC contactors and a motorized cam switch to position the mill.

Hi, by and large I follow your argument, if you halve the ballscrew pitch but double the rpm then the speed remains the same, and assuming a constant torque motor the torque will double. As Jim points out there is a rotational speed limit beyond which ballscrew whip becomes a limiting factor, but there is another maybe even more important restriction. 32mm ballscrews …

Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.

One example of this trend is the use of improved mill drive technologies, e.g., the use of gearless mill drives (for large SAG mills) or of large, geared drives with low synchronous motors and variable frequency drives. "Changing the drive train technology on an existing mill may provide mechanical/electrical efficiency benefits," explained
For less drive power, a direct drive with a toothed wheel and pinion is ideal. In both gear unit types, the girth gear and the slide ring with sliding shoes are incorporated in a single
