Dry grinding uses no liquid during processing; instead, it relies on friction alone to grind materials together. The basic difference between wet and dry grinding lies in how water is used during processing. Dry grinding uses no liquid; instead, it relies on mechanical forces alone to crush particles into smaller pieces.
