rotary kiln operational formula

From ICR's Plant Operations Handbook: Retention time: t=11.2 L / (r D s) Where L= kiln length (meters), r=kiln speed (rpm), D=effective diameter (meters), s=kiln slope (degrees) Retention time should be 20-30 min for most calciner and preheater kilns. Calciner kilns can accomodate shorter times

    Rotary kiln systems typically include secondary combustion chambers of afterburners to ensure complete destruction of the hazardous waste. Operating kiln temperatures range from 800°C to 1,300°C in the secondary combustion chamber or afterburner depending on the type of wastes. Liquid wastes are often injected into the kiln combustion chamber

    The process of direct reduction is carried out in a rotary kiln where the operating temperatures are maintained in a range from 1,000 deg C to 1,100 deg C. The product of the kiln (DRI and char mix) is then cooled in a rotary cooler with external water cooling system. The products of the kiln is screened and magnetically separated
