Control rotary type kilns to calcine chemicals or clay or cement slurry.
What does a Rotary-Kiln Operator do?
Controls rotary type kilns and auxiliary equipment, such as conveyors, feeders, and dust collectors, to calcine chemicals, raw ground stone, gypsum, slate, or clay or cement slurry: Lights burners, starts equipment to feed materials, and moves controls to rotate kiln drum, start dust collecting mechanism, and regulate damper. Observes color and shape of flame, monitors gauges, and moves controls to regulate feed of fuel to maintain specified temperature. Records data, such as kiln temperature, fuel consumption, and power consumed. Inspects kiln for accumulation of clinkers and deterioration of lining. May fire tripod-mounted shotgun to blast clinkers from kiln wall. May tend cooler mechanism. May tend grinders and vibrating screens to pulverize and size product prior to calcining.
