When processing bulk materials, knockers or impactors are used to improve material flow and effectively remove stubborn blockages such as adhesions and bridging.
The pneumatic knockers from NetterVibration’s PKL series deliver powerful, controlled hits without damaging silos or pipes. They replace manual “silo hammering” with rubber mallets: the same effect, but safe, efficient, and without deformation.
Electric twin
The long-established PKL 740 now has a brother that operates electrically, making it incredibly versatile and suitable for use almost anywhere, even as a mobile unit with a rechargeable battery, for example at silos in remote locations without a power supply.
The compact control unit triggers one-off or regular pulses. It can also be integrated into modern control systems and thus offers expandable, process-dependent options, such as integration into the measurement of the fill level in silos to avoid unnecessary impacts.
