The effects of temperature on autogenous grinding can be immediately divided into rheological effects and mechanical effects. The rheological effects are a result of the substantial increase in the viscosity of water as the freezing point is approached. The change in apparent slurry viscosity which results from changing temperature is shown in Figure 1.

Jul 01, 2008· Beads must have sufficient energy to break the target particles and must be large enough to effect comminution. The minimum bead size relates to the size and hardness of the target particles. The bead must be 20 to 40 times larger than the feed material to effect grinding. Typically this ratio falls within the range of 2040:1 (Figure 2).

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners.

The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput 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.
