STIRRED MILLING TECHNOLOGY Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in between each
A VSI mill throws rock or ore particles against a wear plate by slinging them from a spinning center that rotates on a vertical shaft. This type of mill uses the same principle as a VSI crusher.. Tower mill. Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in …
Finest wet grinding technology – the laboratory mills of the MicroSeries are an investment in the future for new product developments of different fields of application of pigmented ink jets, technical ceramics, cosmetics, pharmaceutical applications and nano-scale high-tech products.
The NETZSCH Discus system is the quantum leap in disk grinding technology. The further optimized Discus disk agitator combined with the NETZSCH DCC ® separation system guarantees you extremely high throughput rates with significantly narrowerd well time distributions and therefore more intensive grinding with uniform impact intensity.. The power input of the mill …

Most importantly, the mills are customisable to each unique mining application, optimizing the performance of the mill and recovering more ore for your business. Our stirred mill and tower mill solutions offer a range of advantages, designed to optimise your milling while solving a number of issues traditionally related to industrial grinding:
A Great Australian Mining Innovation Past, Present, Future ... - 100 litre Netzsch high speed horizontal stirred mill ... • In the decade to 2010, the number of stirred mills in PGE industry in S. Africa increased from 0 to 40 (>80% being IsaMills). M10,000 IsaMillTM
The IsaMill is a horizontal stirred mill with sizes up to 3 m3 chamber net volume and 1120 kW installed motor. It was jointly invented by Mount Isa Mines of Australia and Netzsch Feinmahltecknik of Germany for ultra-fine and fine grinding duties in the minerals industry.
CFD modelling of a horizontal stirred mill has provided predictions of the flow … request.This product is particularly suitable for vertical stirred mill, … Stirred Milling VERTIMILL? Grinding Mills & Stirred Media …
In this work, the effect of stirrer speed on grinding performance in terms of grinding rate and grinding energy efficiency was quantitatively investigated. Batch wet grinding tests of quartz powder at different stirrer speeds were performed, using a self-made horizontal stirred mill with alumina balls as grinding media.
Stirred media mills are relatively new to mining industry, and several new technologies have been developed such as the VXPmill (vertical stirred mill). There is little technical understanding of optimizing and scaling-up of the VXPmill. This thesis addresses both of these issues and therefore supports commercial applications of this vertical stirred mill. Stirred media mills …
The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
The VXPmill is a vertically oriented stirred media mill that is open to the atmosphere. They are designed with a modular impeller that has removable discs and spacers. Slurry enters at the bottom, travels upward through the mill chamber, and overflows through a …
Figure 1: Vertical and horizontal stirred media mill orientations. Mill Configuration o Impellor design, o Mill speed, o Media size, o Media load, and o Media density The first of these, material feed characteristics, is difficult to control because it is largely determined by the ore body and prior metallurgical processing.
– Horizontal, high intensity stirred mill -> high energy efficiency – Inert grinding environment -> selective flotation, high recovery – First full-scale IsaMill installed Pb/Zn circuit Mount Isa, 1994
It is also recommended that a comparative study between a vertical and horizontal stirred mill be done, as horizontal stirred mills are more prevalent in the South African minerals processing industry. viii . List of Figures . A. Figure 2.1: Schematic showing energy consumption versus product size (P80) comparison
Stirred milling using either horizontal or vertical mills has made a rapid entrance into PGM ore and tailings concentrator flow sheets. Currently there are in excess of 40 units installed in either mainstream, 'MIG' or intermediate concentrate regrind, 'UFG',
