calculation approach of barrel anxiety of rotary kiln

The major ones are cementkilns, lightweight-aggregatekilns, halogen-acid furnaces, and metal-recovery and smelting furnaces. Cement is produced by feeding raw materials into arotary kilnand burning them with fuel under controlled-temperature conditions. Suitable hazardous waste is used as an auxiliary or replacement fuel.
