Jan 10 2020 0183 32 The first step is deciding if you need a vertical or horizontal cutter Vertical mills are the newer form of milling machines and use a die-sinking method They cut using vertical planes and come in three basic sub-categories bed mills turret mills and mill-drills They are also better for those working on multi-sided piec...

A VSI mill throws rock or ore particles against a wear plate by slinging them from a spinning center that rotates on a vertical shaft This type of mill uses the same principle as a VSI crusher Tower mill Tower mills often called vertical mills stirred mills or regrind mills are a more efficient means of grinding material at smaller particle sizes and can be used after ball mills in a...
