Case Study: Fluid Bed Dryer-Screener System Quadruples Production Of Granular Chemical

A 48-in (1220mm) diameter Circular Fluid Bed Dryer equipped with an integral circular vibratory screener quadrupled production of a proprietary granular chemical product, and improved quality by increasing the consistency of drying times.

The product is comprised of a granular carrier material, a filler material and an active ingredient. The granular carrier is screened into a narrow size range using a 48-inch (1220 mm) diameter, two-deck Kason VIBROSCREEN® circular vibratory screener, after which the filler material and active ingredient are added, and the batch undergoes a proprietary conversion process.

A 48-inch (1220 mm) diameter Circular Fluid Bed Dryer reduces moisture content of the converted material to less than 1.0 percent at 120° F (49 °C), after which it is discharged into an integral 48-inch (1220 mm) diameter, two-deck VIBROSCREEN separator that removes (oversize) agglomerates and (undersize) fines, and discharges into storage containers at a rate of 2000 lb/h (907 kg/h).
