Speeds cleaning, screen changes
This Vibroscreen® High Capacity, Two-Deck Classifier said to be the industry's largest, separates up to 70 tons per hour of bulk solids into three fractions.
Measuring 100 in. (2540 mm) 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. 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.
The classifier 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.
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 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 in. (460 mm), and is available to 3-A, FDA, BISSC and other sanitary standards, as well as to UL, ATEX, CSA and CE electrical standards.
