Impact roller breaker

摘要

The rotary driven impact roller has detachable impact elements (4) set adjustable in holders (5). The holders consist of insert pockets (6) running across the rotary axis of the roller (1). The strip-type impact elements are displaceable in the pockets in the longitudinal direction and can be fixed in different adjusted positions. The insert pockets can be formed continuous along a chord of the roller. The impact elements can be adjusted into at least three to six stages in the longitudinal direction. These impact elements are pref. made of one-piece cast members.
