Oct 04, 2017 to make a ball mill, start by building a wooden platform and attaching a motor underneath it. then, cut a slit into the wooden platform for the belt to pass through and attach casters to the platform for the container to sit on. next, thread the belt through the slit and position the container so the belt is pulled tight.
Several types of ball mill drives can be furnished, made up of various combinations of gearing, motors and transmission equipment. the correct combination to be selected takes into consideration power requirements, gear ratings, floor space, interference from other plant equipment and motor characteristics. the main types are described and illustrated on these pages.
The ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 11.5 times the shell diameter figure 8.11.the feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
