the grinding machines are powerful tools that use abrasive wheels as cutting tools. there are many types of grinding machines, and the most commonly used is the ball mill. the ball mill is a piece of grinding equipment which grinds materials into fine powder in a very efficient manner.
vibration mills are similar to ball mills in that particles of the materials are crushed between porcelain or metal balls and the mill body. drugs and excipients are readily ground to less than 5 mm, the grinding time being considerably less than is required in normal ball milling.
maximum rod length is about 6 to 7 meters, otherwise there is a risk of the rods bowing. the drum diameter is limited to 0.6 or 0.7 times the length of the mill. rod mills are used for grinding hard minerals. this type of mill is normally used as the first stage of a milling process to provide a reduced size feedstock for a further milling process.

for the grinding of the largest quantities of material however, the ball, tube or rod mill is used almost exclusively, since these are the only types of mill which possess throughput capacity of the required magnitude. thus, it is the extremely wide range of applications, and the great industrial importance, of the mills which constitute the tumbling mill family which forms the justification for the present work.
