The stirred milling technologies can be divided into two subcategories: gravityinduced stirred mills and fluidized stirred mills. Gravityinduced stirred mills initiate a ball charge motion via rotational movement of a screw to provide a size reduction mechanism. In contrast, fluidized stirred mills use a rotational movement to fluidize a ...

A comparison of energy requirements and rheological properties has been carried out for grinding of coal/water slurries produced in highspeed stirred and conventional ball mills. In each case, a linear population balance model using specific energy input as a reduced time variable resulted in a satisfactory description of the size distributions.

Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.
