K-Tron Introduces Activator

September 29, 2008

Prevents bridging and rat-holing of bulk materials.

The K-Tron Process Group has introduced ActiFlow, a new alternative to other forms of mechanical hopper agitation. The ActiFlow Smart Bulk Solids Activator reliably prevents bridging and rat-holing of cohesive bulk materials in stainless steel hoppers. ActiFlow is a non-product contact device, consisting of a patent-pending vibratory drive and in­telligent control unit.
In applications involving difficult flowing materials, ActiFlow eliminates the need for mechanical agitators with secondary motors and gearboxes, as well as the need for flexible side wall agitation devices or aeration pads. The patent-pending self-tuning algorithm implemented in the K-Tron Control Module (KCM) monitors the system continuously adjusting the frequency and amplitude of the ActiFlow to maintain flow within the hopper. In this manner, bridges and rat-holes are prevented before they can form.
ActiFlow greatly simplifies the cleaning process during material change-over and reduces headroom requirements. The device is bolted to the outside of the extension hopper, above the feed screws. Together with the K-Tron Control Module (KCM) and ActiFlow control unit, it continuously activates the material inside the hopper with an optimized frequency and amplitude based on changing material flow conditions.
