Water is used in "wet Grinding" for mineral transport through the grinding machine. It may aid in grinding size reduction. Usually, the liquid viscosity strength is raised to facilitate this action. JK Institute did testing on the viscosity vs. grinding action and found you need more than 200 centistrokes to make a difference.
