THE HAZEMAG PRIMARY GSK-TYPE ROTOR – The SK-type rotor (6 row design) is normally utilized for the reduction of lower abrasive, lower strength, shot rock limestones. As a result of its heavy duty design, this rotor is capable of reducing minus 60” shot rock material. Thanks to this exclusive HAZEMAG design, the blowbars are clamped in the rotor body and secured through a mechanical wedge locking system. The blowbars are reversible (1 time) for optimum wear life. Their rotation or changeout is simplified through the wedge release system and impactor downtime is reduced. This rotor design is available on the primary impactor models: APP, APPM, APPE, APCM, and APPH.
