Consistent material flow in an organic mill: vibration prevents bridging and downtime during silo discharge of flour and meal

To improve material discharge and stabilise bulk material handling processes, PKL pneumatic interval impactors from NetterVibration are used. These generate targeted mechanical impulses on silos, bunkers and associated components. The Netter Adhesive Mounting Console (NKK) enables permanent installation without the need for subsequent welding work on existing plant equipment. Netter adhesive mounting consoles ensure efficient energy transfer between the pneumatic impactor and the affected vessel, silo or hopper. Installation of the NKK is straightforward and comparatively fast, as the console is fixed using a specially developed elastic adhesive and subsequently serves as the support medium for selected impactors. Installation can be carried out during ongoing operations without prolonged interruption to production processes, thereby minimising downtime typically associated with welding or bolting. The positioning, configuration and control of the PKL units are individually adapted to the respective process steps and site-specific conditions such as silo geometry, material properties and installation constraints. This ensures effective impulse transmission without adversely affecting plant operation. Adhering or compacted materials are reliably dislodged by the impulse effect, significantly improving discharge from silos and big bag stations. At the same time, the performance of pneumatic conveying and dedusting systems is stabilised, as material build-up in filters and cyclones is reduced. Vibration-assisted operation acts across multiple process stages—from silo discharge and dosing points through to filter cleaning—thus contributing to a more uniform and stable material flow.
