Retrofitting bins, hoppers, and feeders to solve flow problems
the entire hopper outlet to ensure mass flow. A poorly designed feeder or partially opened gate valve can effectively reduce the hopper outlet size, resulting in funnel-flow problems regardless of the hopper design. In many cases, retrofitting the screw, belt, or rotary valve feeder can effectively improve material flow. Mass-flow screw.
