Spray Drying 1 21/6/01 2:26 pm Page 3 SPRAY CHARACTERISTICS q The SDX series nozzles produce a hollow cone spray pattern with uniform particle size distribution even at low operating pressures. q Flow rates are certified to be within ±5% of rated capacity at 69 Bar.G. and within ±5º of rated spray angle when tested with water. q Unique, patented single inlet, spiral swirl chamber offers increased nozzle life, improved product uniformity, density or solubility. q Minimal friction due to nozzle design permitting 10-20% lower operating pressure than conventional slotted distributor nozzle for equivalent atomisation quality. q Extended pump life due to lower operating pressure. q Reduction in fine particles is possible due to lower pressure requirements. CONSTRUCTION AND MATERIALS q Eight part construction (see part and material list below). q Nozzle bodies, screw pins and adaptors are available in 316 Stainless Steel. Other materials available on special request. q Orifice discs are easily removable and are available in Tungsten Carbide, Chrome Carbide and Ceramic as standard. q Swirl chambers are standard in Tungsten Carbide, Hardened Stainless Steel or Ceramic. q End plates are available in Tungsten Carbide, Chrome Carbide and Ceramic. q Combined swirl chamber/end plate is available in Tungsten Carbide only. q Seals are available in Nylon, PTFE, Copper, Hard Fibre and Aluminium. ORDER EXAMPLE Max. Design Pressure: 500 Bar.G. Max. Design Temperature: 540ºC (Metal Seals), 150ºC (Other Seals). Please indicate all component parts and materials when ordering.
