Efficient: This type of rod mill has a more uniform discharge particle size, less crushed ore particles, and higher yield. Convenient: Built-in fineness control device, the particle size of the discharge can be changed by simple adjustment, and the screening device can also be installed when discharging, which can ensure that neither over ...

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 ...
