Stage 4 Finish Process Cement Production

The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

How I built a quick and easy home made ball mill

It was found early on in using the mill that the drum tended to slowly walk toward one side and would eventually drop off the wheels. So I found a scrap piece of aluminum and mounted it the end the drum walked toward to act as a stop. The drum riding against the smooth aluminum surface doesn't seem to produce much friction. The ball mill is powered by a fairly robust 12V DC motor salvaged from
