### 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

Answer You need to keep a steady drip on the sphere during grinding to flush out the loose particles during the grinding phase. If the sphere is covered with slurry then you need to increase the drip just a bit. When polishing I start out with a light drip on the sphere using Velcro diamond pads and adapters (see above) or cut pieces inside of
