K-Tron Quick Change Feeder (K2-ML-T35) with ActiFlow is specially designed for applications requiring the maximum possible material handling and changeover flexibility along with the convenience of fast cleaning. The feeder is available in volumetric or loss-in-weight configurations, both as single or twin screw. Single screw units handle free-flowing powders, granules, pellets and other non-flooding materials, while twin screw units control floodable powders and more difficult sticky or hard-to-flow materials. ActiFlow reliably prevents bridging and rat-holing of cohesive bulk materials in hoppers. It is a non-product contact device, consisting of a patent-pending vibratory drive and intelligent control unit.
