REDC Materials Handling RotoFeed range is designed to effectively inject solid materials into processes, either continuously or on a batch basis, to one or multiple points.
This system injects materials with accuracy of 2% by volume or 0.5% by weight, depending on the control method employed - volumetric or weigh related respectively. Materials can be injected into processes at distances of up to 500 meters, with back pressure of up to 30 bar(g).
The vessel utilises two unique REDC products - the Dome Valve and the RotoFeed dispensing unit.
Rotofeed--How it works
The Rotofeed machine consists of two pressure vessels, a rotating volumetric feeder at the outlet and valves to control the air supply, material flow and vessel pressures.
The dispensing vessel is used to provide a constant supply of material to the volumetric feeder. When material is being injected, the dispensing vessel will be pressurized. The lock vessel is used to periodically replenish the dispensing vessel with material. In this way, injection of material to the process can be continually maintained. The conveying air will enter the cupola along with the material and will leave the cupola along with the other process gases RotoFeed applications.
