  • What is an inching drive? - Motion Control Tips

    02-05-2018 · 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 120 percent of the

  • How To Make A Variable Speed Ball Mill From A Drill - YouTube

    05-09-2013 · A very useful bit of kit - so i thought i would give it a go making a ball mill from the odd things i found around my shed - i feel like a womble now!

  • How I built a quick and easy home-made ball mill

    One of the few things I had to buy for this project, aside from the casters, was the steel balls. I found these online. They were quite inexpensive. I went with 5/8 inch diameter balls, which seem to work well in a mill this size. I have been powering the ball mill with my bench variable power supply so I could fine tune the rotation speed.
