the basic condition, which must be met while grinding the material in a mill is that the ball, while breaking the material grain, causes in it stress which is higher than the grain hardness therefore, for the biggest grain size, it is necessary to have a definite number of the biggest balls in the charge,
involve grinding). with lloyds ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just america alone. this article borrows from lloyds research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
In the complex mineral grinding process, ball mills are the most important key devices in maintaining the stability, improving the grinding production rate and the products quality however, it is very difficult to maintain an optimized grinding condition for the grinding process. accurate measure load parameters inside the ball mill can
