Rotary kiln process An overview of physical mechanisms
The rotary kiln is used in many solid processes including drying incineration heating cooling humidification calcination and reduction This widespread application can be attributed to factors such as the ability to handle varied loads with large variations in particle size [1] The rotary kiln is a slightly inclined steel cylinder that rests on supports bearing rollers with
Extending refractory lifetime in rotary kilns for hazardous
Hazardous wastes include pesticides oils waste fuels acids filter cakes and aerosols to name but a few The rotary kiln is the state of the art technology to incinerate hazardous wastes thanks to its high capacity up to 120 000 t/y and versatility [1] [2] Rotary kilns are able to treat solid pasty and liquid wastes all kilns are from 5 to 15 m long
