The High Efficiency Cyclones are the product of significant development with the aim of achieving extremely high levels of particle removal from the airstream. The unique inlet scroll is designed with a smooth flow elbow to eliminate currents perpendicular to the main direction of gas flow that is present in standard conventional rectangular entrance cyclones. The epically designed inlet scroll gradually introduces the particle-laden gases into the cyclone while keeping the flow smooth and uniform which thus leads to higher efficiencies then in conventional cyclones. Custom designed disengaging hoppers give highly effcient separations by creating a void that hosts the bottom section of the descending vortex and allows the particles to disengage the airstream before it ascends into the gas outlet tube. A range of hopper storage designs are also available to meet customer needs. A wide range of manufacturing materials are available to meet the process demands. For abrasive feeds, the classifier unit is manufactured from abrasion resistant plate. The high wear zone in the inlet scroll can also be lined with ceramic tiles to significantly increase maintenance intervals. Other manufacturing options include aluminum and stainless and mild steel. Cyclone size options start at 0.5m3/s (1,000cfm) – 10 m3/s (20,000cfm) for single unit cyclones and up to 50 m3/s (100,000cfm) for individual multi cyclone options. Expert cyclone applications assistance will ensure the correct cyclones will be selected for every duty required.
