Wet mills can also be adjusted to reduce the likelihood of wear to the milling media or grinding chamber. If a product needs to be in a dry powder format, after wet milling it requires an energy-intensive drying process. Dry milling techniques, including fluidized jet milling with superheated steam can save this step, possibly also sparing costs.
