Ball Mill vs. Vertical Roller Mill
May 05, 2020· Ball mill vs. Vertical roller mill Does anybody have any information on the efficiencies gained from going from ball mills to vertical roller mills? I heard that a vertical roller mill uses 56KW/ton when feed 3" minus material and crushes it to 35 microns, would this be correct? 7th April 2008, 0:33 #2.
