The stirred mills are charged with a media size of 1012 mm and operated at a maximum tip speed of 38 m/s. The detritor mill, however, has a maximum tip speed of 1112 m/s. Even though a finer ground product is obtained with higher speeds, a limit has to be imposed.
It is a wellknown fact that it is challenging and highly timeconsuming to achieve ultrafine particle sizes in the dry environment of a typical tumbling ball mill. This issue appears to happen because of ball coating by fine particles or a bed of fine cohesive materials that cause almost liquidlike properties, making the whole grinding ...
