This reaction is a result of a differently acting "bed of pulp" and lack of grinding media "coating". Due to a common "swelling action" of dry material being ground, the grinding media level is often reduced to approximately 40-42% of mill volume. Dry grinding offers less steel consumption than its equivalent wet grinding counterpart. COKE GRINDING
