Prediction of product size distributions for a stirred ...

1995-8-1  A size-energy model is proposed for simulation of stirred ball milling. The product size distributions below 10 μm from a stirred ball mill were simulated by the model satisfactorily. The model is simple and has only two parameters. The model was tested under different milling conditions for a stirred ball mill. Previous article.

Stirred Milling Technology – A New Concept in Fine

2019-5-8  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.

Abstract Studies were made of the grinding kinetics of chromite ore in a stirred ball mill. Grinding tests were carried out using material in discrete size ranges (−53 + 38 μm and −38 + 25 μm) and for material conforming to a natural spread of sizes (−100 μm). Tests conducted on the discretely sized material were used to establish the breakage function for the ore.

Energy Use of Fine Grinding in Mineral Processing

2013-4-25  Gravity-induced stirred (GIS) mills include the Tower mill, produced by Nippon Eirich, and the Vertimill, produced by Metso. Grinding to below 40 lm in GIS mills or ball mills is usually not recommended. In their product literature, Metso give 40 lm as the lower end of the ‘‘optimal’’ P80 range for Vertimills.[6] At lower product sizes ...

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 ...
