Test Lab for Screeners, Fluid Bed Dryers/Coolers

A fully re-equipped test laboratory at Kason Corporation contains a full range of screening and fluid bed processing equipment that is readily reconfigured to simulate customer installations for trials using supplied materials.

VIBROSCREEN circular vibratory screeners include units with single and multiple decks for measuring sifting, scalping, classifying, dedusting and dewatering performance in both gravity-fed and vacuum/pressurized applications. Similarly, CENTRI-SIFTER centrifugal sifters and separators verify sifting, scalping, de-agglomerating and dewatering efficiencies in both gravity- and pneumatically-fed models using customer-supplied materials.

All models of laboratory screeners are quick-clean designs, allowing easy access to interior components for rapid inspection, disassembly, screen changes and cleaning.

Most notable is the lab's new, full-scale, VIBRO-BED fluid bed processing equipment for drying, cooling and moisturizing of bulk solid materials. The exclusive, circular vibratory design enables entire systems consisting of fluid bed processor, heater/cooler/moisturizer, blower and dust collector, to be self-contained on mobile frames with casters, offering testing flexibility not practical with larger, heavier, rectangular units of equivalent capacity.

A full complement of hoppers, mechanical and pneumatic conveyors, and flow promotion devices enables Kason lab technicians to replicate virtually any process layout and production scenario, including running of customer-supplied materials at elevated temperatures.

In addition to providing free testing services for the company's customers prior to equipment fabrication, the test

lab is utilized to test-run completed equipment and to measure performance characteristics of new equipment designs.

The company also provides screeners for on-site trials at no charge to customers unable to ship materials for testing, and offers the equipment for pilot plant testing and other long-term trials on a rental basis. Fluid bed processors are also available for weekly rental for on-site testing.

Kason's line of screeners handles bulk chemicals, minerals, plastics, foods and beverages, dairy products, pharmaceuticals and other materials ranging from dry bulk solids to solids-laden slurries containing particles from 5 cm to 25 microns (500 mesh) in size, at capacities in excess of 50 tons/h. Its fluid bed processors dry, cool, or moisturize bulk materials on a batch or continuous basis, on a laboratory or production scale.
