Get Price And Support OnlineBall mills may be able to efficiently reduce coarse aggregate to particles as small as 30 to 40 microns. Below 30 microns, the advantages of a horizontal stirred mill become dramatic and below a certain point, the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption.
Get Price And Support OnlineThis accurate scale up is different than scale up for ball mills or other stirred milling technologies. In ball mill laboratory tests 25mm balls in a small laboratory ball mill have different trajectories and interact differently with the shell lifters and ore particles than in a large production ball mill.

Get Price And Support OnlineStirred mills have been proven to provide energy savings when compared with traditional grinding mills. The finer the product required, the more efficient stirred mills will be. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills energy efficient grinding machines.

The shell liner of the mill is easily replaced as the shell is designed in two pieces. Wear within the mill is determined by the specific size reduction of the mill, as well as wear
Get Price And Support OnlineThe 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, it became less so as grinding proceeded and for a product median size of 4.8 microns it was the same.
