Used Thermal Processing Solutions Electrically Heated Rotary Calciner & Rotary Cooler. Consisting of: 36 inch diameter Indirectly Heated Electric Rotary Calciner. Convective Rotary Cooler 24" diameter X 21-0". The Calciner is approximately 36" diameter X 20 heated furnace zone X 35 long overall; 21-0" RA253MA furnace section that extends 6" out of each end of the furnace, and 300 series stainless steel ends, suitable for 1000 degree C operation. The cylinder has seal welded Blanchard ground fixed seal rings if an upgrade to a bellows type seal is needed; These are welded/X-ray inspected as per ASME Sec VIII unstamped vessel construction; Furnace casing is 9" thick Fiberfrax 2200 Dura blanket modules; Zone divider walls are Fiberfrax board; (2) thermocouple assemblies per zone; Heating elements are SiC ceramic, 1600 degrees C continuous duty construction; Heating element access is available on the sides of the furnace. Calciner is complete with freestanding 500 amp power/control panels using Watlow SCRs , F4 PID loop controllers with communication options and EZZone; Watlow High Limit controllers, each monitoring an independent furnace thermocouple in each zone; Includes variable slope support stands with an SCR drive and a dc variable speed screw conveyor; Calciner is set up to discharge directly into a 24" diameter x 21ft indirect convective Cooler, then optionally into a Kason Screener into a bulk bag and oversize/foreign object container.
