• Mill (grinding)Wikipedia

    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
