Vertical Stirred Ball Mills — Хонинговальные головки

The advantages of vertical stirred mills are that balls do not have to be elevated and that ball-to-ball and ball-to-wall collisions are much more rapid than in tumbling mills. Attrition is the important breakage mechanism in stirred mills, whereas impact is signifi­cant in tumbling mills. The early stirred mills were low speed, and these are still used for grinding at the coarse end of the very fine-grinding spectrum. Higher-speed stirred mills

A study of comminution in a vertical stirred ball mill.

The stirred ball mill has been found to be more energy efficient than the tumbling ball mill. An energy reduction of 50% was possible for a product size of 6 microns when the stirred ball mill was employed instead of the tumbling ball mill. The energy input per ton of grinding media in the stirred ball mill could be 10 times higher than for the tumbling ball mill. Although during coarse grinds the media wear was higher in the stirred ball mill than in the tumbling mill

Fine Grinding Technology for Mines and Concentrating ...

The vertical stirred mill showed energy savings of 25%, 37%, and 27% relative to a ball mill in coarse grinding duty. For desired particle sizes less than 40 microns, horizontal stirred mills show increasing advantages over ball mills. Both ball and stirred mill specific energy (kWh/tonne) depend heavily on ore type, feedstock size, and ground particle size.
