Vibratory Classifier Separates up to 70 Tons per Hour

June 14, 2011

The new Vibroscreen® High Capacity, Two-Deck Classifier separates up to 70 tons per hour of bulk solids into three fractions. Measuring 100 inch in diameter, it classifies bulk chemicals, minerals, plastics, foods, dairy products, pharmaceuticals and other materials ranging from dry bulk solids to solids-laden slurries. Quick-disconnect clamps between each screen frame provide rapid interior access for inspection, screen changes and wash down. The classifier contains two horizontal screens located one above the other in a vertical, cylindrical housing supported on a circular base by rugged springs. Material to be separated is fed onto the center of the top screen, whose mesh is the largest. Oversize particles are moved to the screen periphery in a spiral pathway, and discharged through an outlet, while undersize particles drop through to the center of the next screen. The mesh sizes become progressively smaller toward the bottom of the screener. The gravity-fed unit can operate on a batch or continuous basis. Constructed of epoxy-coated carbon steel, it is also offered in stainless steel finished to industrial or sanitary standards. Other options include various anti-blinding devices, Clean In Place (CIP) construction, and automatic lubrication systems. The classifier is also offered in diameters down to 18 inch, and is available to 3-A, FDA, BISSC and other sanitary standards, as well as to UL, ATEX, CSA and CE electrical standards.
