tower mill grinding efficiency Process Modelling of Gravity Induced Stirred Mills - UQ eSpace more efficient technology selection compared to the ball mill for fine grinding ( 100 µm) The , Tower Mill Most of the , Figure 25 - Effect of media size on mill efficiency for the (a) Vertimill and (b) SMD (Lichter and Davey, 2006)
Rod mills are less common than ball mills for grinding minerals The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency Autogenous mill
The effect of low ball% full on grinding efficiency is: The throughput of mill will decrease with the time; The P80 in the discharge of the Mill, will increase because of the high time of particle residence in the Mill, and for this reason the grinding will be lower efficient The power specific consumption will increase, due to the lower feed .
Over the last ten years Tower mills were studied and used for regrinding and fine grinding applications at MIM operations They were found to be more energy efficient than regrinding tumbling ball mills, more reliable, and easy to operate and maintain Tower mill grinding efficiency drops as feed material becomes finer then 25
Swiss Tower Mills Minerals AG develops fine and ultra-fine grinding mill products, using an innovative technology A range of services is available from consulting, conceptual and detail engineering to production, site assembly and lifecycle service support
A convenient way to compare the Tower mill grinding efficiency with that of other mills is to develop a correlation between net specific energy and product size This would be desirable not only for comparative purposes, but also for design and scale-up calculations
