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.
Conical Ball Mills Used wet or dry, closed or open circuit, conical ball mills provide a classifying action within the body of the mill due to particles of greater size tending to reside at a point of greater diameter. This characteristic delivers increased efficiency and lower power consumption. Conical mills may also be air-swept when run dry.
