If a ball mill uses water during grinding it is a wet mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.
MVR vertical roller mill with conventional drive. With a planetary gearbox and up to six grinding rollers the MVR mill is the optimum solution also in terms of economy - when it comes to producing small to medium output rates.
Apr 25 2016 In a simple grinding circuit there will be a ball mill and a classifier. Some circuits especially in large mills have more units or two or three stages of grinding but whatever is said here will apply to the complicated circuits as well as the simple ones. The two types of ball mill in general use are the grate mill and the open-end mill.
