The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured. The grindability is useful in evaluating power requirements for grinding.
The Hardgrove Method.* This method consists of grinding a 50-gram sample of coal, sized between 16- and 30-mesh in a ball mill consisting of eight one-inch steel balls rolling on a stationary ring and driven by a rotating plate for 60 revolutions at a speed of 21 rpm. A screen analysis is made using sieves of 16-, .
