the grinding energy efficiency can be established, e.g. use of smaller grinding media, choosing larger particle size class materials, etc. Keywords: nanoparticles, stirred media mill, grinding energy efficiency, production rate constant 1. INTRODUCTION Ultra-fine grinding of subs tances in the sub-micron range
Grinding and energy input in stirred media mills are studied as functions of grinding time, stirring speed, media size and density, solid concentration, impeller and lank dimensions and design, and other relevant variables. Ground prOduct size and surface area are determined with respect to the above variables.
The use of finer media also results in reduced energy input probably due to increased " fluidity". These results agree with those reported by Orumwense and Forssberg  for dolomite samples ground in an annular ball mill. Effect of media density. The effect of media density on the grinding of limestone is shown in Table 2.
stirred mills will vary from site-to-site and from mill-to-mill. Optimization of a given stirred mill with respect to specific energy input depends on the complex relationships between a large set of parameters. Examples include mill speed, media size, media loading, slurry density, slurry flow rate, slurry rheology, feed material characteristics.
On the other hand, the grinding media in the horizontal stirred mill moved more uniformly but with a lower collision energy. Furthermore, the grinding media in the low sections actively mixed with the grinding media in the upper sections, thereby resulting in a more uniform energy transfer and in a better grinding process.
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.
Thiel, 1993, Theuerkauf, 2000, Theuerkauf and Schwedes, 2000 both used transparent grinding chambers to examine the phenomena of grinding media motion and distribution in a stirred media mill. The disadvantage of these optical approaches is the fact that they only spot the grinding beads which are close to the grinding chamber liner.

Graphical abstract. This study investigates how the shape of grinding media in stirred mills influences grinding performance. Specifically transport properties, stress distribution, energy dissipation and liner wear are all shown to be sensitive to media shape.
of inert stirred milling are available to high tonnage, mainstream grinding. The IsaMill™ reduces the energy cost, media cost and capital cost of grinding. Further, the intense inert attrition frequently improves metallurgical performance compared with conventional steel media. The IsaMill™ produces a steep particle size distribution in open

The two grinding media have diﬀerent surface area, bulk density and contact mechanisms in grinding action. Comparative tests were conducted using the two types of grinding media in a laboratory Bond ball mill at various conditions of equality such as media mass, size distribution, surface area and input speciﬁc energy.

The mill heights can be varied to optimize the media load and power input for specific applications. Chamber volumes range from 5 to 30,000 liters with corresponding drives from 5 to 5000 kW. The HIGmill is the only ultrafine grinding technology in commercial use that can use small-size high-density grinding media in mill sizes above 3000 kW.
