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

The drum I used for the ball mill was originally a plastic container that held abrasive grit used in vibratory tumblers. It is about two liters in size. I had several empty containers of this type, and decided to put them to use in this project. They work pretty well in this application. There are a few potential problems. The container lids are not liquid-tight. So use as a rock tumbler would

A Bond Ball Mill Work Index test may be required for the design of a new mineral processing plant. Where possible, it is carried out on a sample of ore that is typical of the proposed feed to the plant. The BBMWI is then used in the design calculations of the new grinding circuit. A BBMWI may also be used in the simulation and subsequent optimisation of existing mill(s) and the associated

The Bond's standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatt-hours per short ton required to break from infinite size to a product size of 80% passing 100 µm. If the breakage characteristics of a material remain constant over all size ranges, the calcul ated work index would be expected to remain constant since
