# ball mill efficiency vs temperature

### How Temperature Affect Grinding Efficiency

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 As can be seen, the effect at high.
