Material Flow Aid New Material Flow Aid Prevents Bridging of Cohesive Bulk Materials in Hoppers
K-Tron’s ActiFlow is a new alternative to other forms of mechanical hopper agitation. ActiFlow reliably prevents bridging and rat-holing of cohesive bulk materials in stainless steel hoppers.
It is a non-product contact device, consisting of a patent-pending drive system and intelligent control unit. For difficult flowing materials, ActiFlow eliminates mechanical agitators with secondary motors and gearboxes, and eliminates the need for flexible side wall agitation devices or aeration pads. The new material flow aid 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 ActiFlow control unit, it continuously activates the material inside the hopper with optimized frequencies and amplitudes. The ActiFlow is used in loss-in-weight (gravimetric) feeding applications.
