    Grinding Theory: There are a lot of misconceptions about what goes on in a ball mill. We know that a drum filled with heavy metal objects will grind powder when it is rotated, but how exactly does this happen? Some people think that the powder is pulverized against the sides of the drum as the media roll over top of it. Others believe the grinding media should drop down onto the powder grains ...

  • Dry Grinding VS Wet Grinding

     · Furthermore the throughput of a continuous feed mill is greater in wet grinding; probably due to the better flow properties of a pulp in comparison with a dry material. It appears, however, that the rate of ball and liner wear is greater in wet milling so the decision between wet and dry operation is, in cases where the choice is permitted, a matter of balancing the economic gain arising from ...
