Available in a range of configurations, including rectangular sizes and round inlet/outlet transitions, the roller gates are suitable for handling dry bulk material in gravity-flow applications where positive material shutoff and a dust-tight seal are required. The roller gates can be applied to shut off or meter the flow of fine and moderately abrasive powders and small to large granulars or pellets.
