Grinding Roller as grinding media (1 reply and 2 comments)
Please join and login to participate and leave a comment.
Propose to employ free floating grinding roller instead of balls or rods in a ball mill. Can we run the mill at 150 to 200 percent critical speed? How to assess the mill drive power in this case? Any formula? Air flow through the mill can be up to 4 m/sec . The product can be either air swept or peripheral discharge. Dry grinding. Pl clarify. Thanks
