Sanitary classifier

A new Vibroscreen two-deck sanitary classifier reportedly separates up to 6 tons of bulk solid material into three fractions each hour. The machine, which measures 30 in. in diameter, classifies bulk chemicals, minerals, plastics, foods, dairy products, pharmaceuticals and other materials, ranging from dry bulk solids to solids-laden slurries. It is made of stainless steel with ground and polished welds, and equipped with sanitary epoxy-mounted screens. Quick-disconnect clamps between each screen frame provide rapid interior access for inspection, screen changes and wash down. An optional Air-Lift device pneumatically raises any of the screen frames, enabling one operator to rapidly perform what was previously a two-person task. Also, the dust-tight, gravity-fed unit contains two horizontal screens located one above the other in a vertical, cylindrical housing supported on a circular base by rugged springs. An imbalanced weight gyratory motor affixed to the housing imparts vibration.
