IDMS 50/100 Blow-Through Rotary Valve for Alternative Fuels .. In-line feeding of non-homogeneous alternative fuels into pneumatic conveying systems .. Compact, space saving, blow through design for feeding cohesive alternative fuels .. High degree of filling through large inlet section .. Robust cutting blades for reliable size reduction of oversize material .. High abrasion resistant wear parts all exchangeable from the plant side .. Conveying pressure of up to 300 mbar .. Volumetric feed rate up to 150 m3/hr Application The IDMS Blow-Through Rotary Valve has been especially designed and developed for the in-line feeding of non-homogeneous alternative fuels into pneumatic conveying systems within the Cement, Lime, Gypsum and Power industries. Robust in design and performance the IDMS is capable of feeding a wide range of alternative fuels including shredded plastics, foil chips, conditioned sewage sludge, wood chips & saw meal, shredded tyres, palm kernel shells, rice husk, animal meal and various mixed combinations. Design A robust, compact, space saving design ensures high efficiency performance. Durable and reliable air-sealed bearings protect the units. Wear parts thus ensuring optimal and stable pneumatic conveying conditions with minimal air leakage. The valve is characterised by its design: - High degree of filling through its large inlet section - Integral horizontal conveying channel to ensure maximum material ‘pick-up’ velocity directly into the pneumatic conveying line - Robust integral scrapper designed to prevent blocking of the inlet section - Durable and robust cutting blades for the reliable size reduction of oversize material - Directly mounted geared motor - Air-sealed bearings Operation The IDMS Blow-Through Rotary Valve is used as a feeding device to directly feed of non-homogeneous alternative fuels into pneumatic conveying lines at conveying pressures of up to 300 mbar. Typically, a pre-feed device positioned between the upstream material silo is used to consistently feed the material into the IDMS. The integral scrapper and cutting blades are designed to prevent the IDMS from becoming blocked with foreign bodies or oversized particles. For ease of use and maintenance, the high abrasion resistant wear parts are all exchangeable from the plant side without the need to completely disassemble the unit. The geometry of the unit’s inlet, chambers, conveying channel and outlet guarantee efficient material flow into the pneumatic conveying line thus a high material conveying to air ratio is achieved.
