The Raymond® Vertical Mill is a highspeed air swept swing hammer mill used to pulverize materials in the extreme fineness range. The principle of integral air classification, originally developed by Raymond®, has been applied with outstanding success to this mill. As a result, a large number of products can be reduced to 95% to 99% passing ...
