IsaMill NETZSCH Grinding & Dispersing

The patented IsaMill is a transformation in grinding technology based on high intensity stirred milling. The IsaMill was developed for fine grained orebodies that needed a step change in processing efficiency to be economic. The IsaMill significantly reduces the energy requirement, and media and capital costs of fine grinding. Just as importantly, the processing advantages of inert grinding

IsaMill

stirred mill that operates with very high power intensities (up to 300kW/m3) compared to ball or tower mills (with less than 40kW/m3). This high power intensity enables the IsaMill™ to process coarse particles to ˜ne product sizes with small media at high throughput. The result is large scale, ef˜cient grinding for both coarse and ˜ne particle sizes. The IsaMill™ stirs media with

IsaMill

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 mixing chamber is filled with the grinding medium (normally sand, smelter slag, or c

IsaMill Technology Used in Effecient Grinding Circuits

The IsaMill™ is a horizontally stirred mill consisting of a series of 8 discs rotating around a shaft driven through a motor and gearbox. The discs operate at tip speeds of 21-23m/s resulting in high energy intensities of up to 300kW/m3. Figure 2 illustrates the layout of the IsaMill™.
