Stirred mills are in general applied to fine and ultra-fine grinding applications. For the purposes of this paper, grinds of up to 75 m are regarded as conventional, between 75 and 30 m as regrind, below that and up to 10 m as fine grinding, and finally below 10 m as ultra-fine grinding

1970s. In 1975, centrifugal mills were invented for ultra- fine grinding by exploiting centrifugal forces generated by gyration of the axis of the mill tube in a circle.The mill charge motion depends on the ratio of the gyration diameter to the mill diameter, varying from a motion similar to that of a conventional tumbling media mill to that of a vibration mill

Stirred bead mills find application in a number of industries where there is a need for very fine grinding or particle dispersion. In the minerals industry this type of mill is becoming increasingly important due to processing of ore bodies which are fine-grained and require milling to fine sizes for effective mineral liberation. Numerical simulation of these mills offers a means of

Apr 01, 2003 Traditionally, grinding to 80% passing 75 μm is regarded as “conventional” since many operations grind to that size. Regrinding is considered to produce the particles finer than 75 μm down to 30 μm. Fine grinding is a relatively new area and considers grinding below 30 μm down to around 10 μm
