Configuration Pneumatic Impulse Knocker Type QJ

The Configuration Tool below provides a rough reference for selecting the adequate size and number of Pneumatic Impulse Knockers.

In rotating drums, a knocker is fitted vertically from above striking at a slight angle against the direction of rotation on a traverse.

For the installation and operation guidelines please refer to the components shown in Figure 3.

  • Fitting: The knocker must be well anchored on a larger mass (e.g. machine frame, with poured concrete steel profiles) or be fastened with a solid beam over a drum so that the recoil is absorbed.
  • Pneumatic 3/2 way solenoid valve in the desired control voltage.
  • Electrical control for solenoid valve to desired control voltage. An existing PLC control can also be used.
  • Pneumatic connectors and cables
  • Maintenance unit for pressure reduction to 3.5 bar operating pressure, drainage and lubrication of the knocker is recommended.

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
