WhatsApp: +86 18838072829This 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 4042% of mill volume. Dry grinding offers less steel consumption than its equivalent wet grinding counterpart.
WhatsApp: +86 18838072829The following describes the working principle of the slaked lime grinding mill.
