Engineers at Heyl Patterson Thermal Processing designed a smaller scale rotary dryer to be able to efficiently convey and dry small particles without running into the issues a customer was having with previous drying methods when they changed to a finer particle size. The custom internal lifter flights move and shower the small particles to prevent sticking or agglomeration while drying. This specialized design also produces minimum fines carryover in the exhaust gas. The rotary shell is 19 ft long and is constructed of stainless steel for ease of cleaning between use, and the inlet gas temperature is 300°F for optimal drying of the material without burning it.
