[PDF]A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

[PDF]some of the key design criteria for making your own ball mill. This is a good starting point for anyone interested in making their own black powder, which is the foundation upon which all other pyrotechnics have been built. Grinding Theory: There are a lot of misconceptions about what goes on in a ball mill.
[PDF]The theoretical critical speed of a ball mill is the speed at which the centrifugal force is sufficiently large to cause a small particle to adhere to the shell interior for a full revolution of the mill. The common range of mill speeds is 65% to 80% of critical, depending on mill type, size and the application.

in the design of bearing systems: Whenever you think you have a good design, invert it, think of using a com-pletely different type of bearing or mounting, and com-pare it to what you originally considered. Why did some civilizations discover bearings and others did not? Those with bearings moved farther faster, and history has yet to stop.

The second type of ball mill considered in this paper is the vertical ball mill. Vertical ball mills, as the name suggests, have the mill shell oriented in the vertical position. Unlike their horizontal counterparts, the mill shell does not turn. However, feed size reduction is accomplished through a similar mechanism as the horizontal mill.
