This new combination attritor mill brings greater levels of speed and efficiency to the media grinding process. It combines the benefits of the HD and HDDM attritors into one versatile unit. In the past, a changeover required releasing a belt guard, moving the belt to an alternate set of pulleys, replacing the guard, and changing the coupling, shaft and cover. The HD/HDDM combination attritor eliminates this process and provides the benefit of two mills in one. Both larger grinding media and micron particle size targets can be achieved with a simple changeover. LEARN MORE
