Distance knocker QJ series

pneumaticexternalfor bulk materials

The Pneumatic Distance-Knocker QJ is suitable for knocking against slow-moving drums and filling or emptying stations with moving containers. The knocker type QJ can be mounted at a distance from the rotating drum or a container. The operating principle is identical to the knocker type K, but the impact pulse is transferred to a piston rod which moves to the container. The drum or container wall is touched only briefly during knocking and transmits the impact pulse. The Pneumatic Distance-Knocker QJ is used, for example, in rotary kilns, drum drying systems, filter cup knocking stations, centrifuge drum cleaning stations and many other applications. With rotating drums, a knocker is fitted vertically from above and strikes at a slight angle against the direction of rotation on a traverse. Important parameters for the selection of the right knocker: • Thickness of the container or drum • Material of the container or drum • Diameter of the container or drum • Operating temperature • If present, insulation thickness for the selection of the mounting • Protection type for operating environment
