In some instances, particularly on high capacity check screening or grading applications, product can be discharged from the mesh before it has time to be fully screened. When materials are discharged prematurely through the oversize discharge outlet, this can result in the loss of good quality product. A way to overcome this has been to decrease the feed rate. However, this reduces the throughput rate while also reducing overall efficiency. The Russell Gated Outlet™ eliminates the need to reduce the feed rate and ensures that your product is sieved effectively.The Russell Gated Outlet™ operates via a pneumatically controlled gate, which is placed inside the oversize discharge outlet to control the flow of material. The gate can be automatically opened and closed providing complete control of product discharge. While the gated outlet is closed the product remains on the mesh to ensure it has been screened fully before opening the gate to discharge the product.The outlet can be used on the entire range of Russell Finex sieves and separators, and can be easily retrofitted to any existing Russell Finex sieve. The gate is available in FDA approved natural rubber, neoprene or polyurethane to comply with the needs of a wide range of industries including food, pharmaceutical and chemicals.Key benefits of the Russell Gated Outlet™ include: increased productivity due to oversize material being ejected automatically with no need for manual intervention; improved screening efficiency because product is sieved and only oversize material is ejected through the oversize discharge outlet; and increased profitability because loss of good product is reduced.
