Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.

Attritor Mills & Media for Chocolate Processing Update

a Stirred Ball Mill" presented at the Powder & Bulk Solids Conference, Chicago, Illinois, May 1978. For specific energy input around 100 ksh/t, the media particle size achieved through the use of attritors is nearly one-half smaller than that obtained from conventional ball mills, one-third smaller than vibratory mills. For energy inputs

The impacts of dry stirred milling application on quality ...

A comparison between laboratory ball mill and dry stirred mill showed that the components of the clinker behaved in a different manner thus the strength properties are expected to be different as well. The quality results of the real application of the stirred milling could be higher than that of the laboratory ball milling.

Cement Grinding Optimization - SlideShare

Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5-8 mm range) improves grinding energy efficiency up to 50% using stirred mills.

Stirred Milling Technology – A New Concept in Fine Grinding

al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10 to 40 µm.
