Profile: Rodrigue Metal specializes in the design, manufacture and installation of dust collection and air conveying equipment. We offer a wide variety of products, including structural frameworks, wrought metals, hammer mills, & chippers, as well as custom machining and assembly services. Cyclone and the multi-cyclone use centrifugal action as the basis of operation. The particle-laden air enters the cyclone through a tangent intake. The centrifugal action projects the particles against the cylinder wall, thereby causing a descending spin motion that forces the particles out. As for the air, it is evacuated to the central chimney created by the difference in internal pressure of the cyclone. The multi-cyclone is made up of several cyclones from our HE series, which allows the treatment of a high volume of air.
