A comparative study on the effects of dry and wet grinding on …
In terms of the energy consumption (EC) for a certain particle size distribution, several investigations reveal that in dry grinding the EC is around 15–50% higher than in a wet environment [2], [10], [14], [15].Ogonowski et al. (2018) conducted an investigation to compare wet and dry grinding processes in an electromagnetic mill.

2019 Review of Chairside Milling Machines (CNC)
7. Dry and wet milling function: affects zirconia sintering time. When zirconia is sintered, it needs to start from a dry state. If it is wet, an additional 30 minutes of pre-dry drying process is required. Because of this, manufacturers also introduce dry milling, or models that can switch between wet and dry milling.

wet milling | Craft Beer & Brewing
In wet milling, malt is steeped in a continuous stream of warm water to bring the husk moisture content up to 15%, before the malt is ground on a pair of specially designed rollers. In wet milling, the grain husk remains mainly complete, whereas in a dry mill it can fragment. This fragmentation can slow run-offs and cause quality problems.
