Realizing Energy Savings Using A Ceramic Lined Rotary Valve In Place Of A Screw Pump
Energy saving becomes a more and more important topic in the cement industry. The air supply (screw compressor) and the material feeding device into a pneumatic conveying line are the highest energy consumers of a pneumatic conveying system. For many decades the screw pump is the most frequently used material feeding system, but screw pumps require extremely high electrical power. Looking on this disadvantage of the existing technology, Coperion has adapted the well-known technology of rotary valves for the high wear application in the cement industry. This technology saves more than 95% of power compared to the screw pump.
