Pneumatic Distance-Knocker QJ

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.
