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 classifiion, 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 15 to 20 microns while others with smaller ...
wear liners in vertical roller mills (VRMs) is to reweld or hard face the worn surface. This means regularly stopping the mill. Because the wear rate in a VRM varies, depending on feed materials and product fineness, the number of times maintenance is required over a given time period is variable. With significantly longer wear life than traditional highchrome liners, OK™ Pro+ ceramic wear ...
