United Catalysts, Inc., Louisville, KY
Zinc Oxide Pellets

 

The company wanted to utilize hot exhaust gas from a nearby kiln to uniformly dry and cure 1,500 to 2,000 lb/hr of moist, claylike pellets from 25% moisture down to less than 5% without pellet breakage and attrition. The previous dryer was a batch type box unit. Several types of new dryers were considered. Tests were run by Wyssmont to ascertain that product specifications, especially hardness and attrition, would be met and to determine size of final unit. The TURBO-DRYER® selected has 18 trays. Con-struction is carbon steel except for a stainless steel hot-inlet-air manifold. Hot flue gas is delivered by a blower and automatically controlled by dampers. The TURBO-DRYER® provides greater product uniformity. Savings in fuel, by use of waste heat, is equivalent to 6 million scf/yr of natural gas and there are substantial savings in manpower in operation and maintenance.
