2019 6 12 The entire mill train is approximately 300 metres long. The central components of the system are the work rolls, which have direct contact to the material and ultimately influence the surface quality of the strip. The major part of the roller force is carried by the supporting rolls.
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.
