• Design Velocity In Vertical Mills lustrzankami.pl

    Mills evolved from simple balls mills, to vertical mills, and eventually horizontal mills.The horizontal design did not keep the media from floating in the liquid but it was evenly distributed across the chamber instead of being concentrated in one area.The velocity from the rotating shaft in the interior of the chamber keeps the media.
