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-SifterTM centrifugal screeners 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, 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, 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.
