Using rotary kilns for high-temperature bulk solids processing
Rotary kilns are used to carry out pyrolysis, allowing a wider range of plastic waste types to be recycled — a much-needed alternative for plastics that cannot be processed through traditional mechanical approaches. This process ultimately converts plastics into fuel or the building blocks of petroleum products.

Due to the inclination and rotational motion of the rotary kiln, the raw materials move slowly from the end of the feeder to the end of the discharge or charge. During the movement, the iron ore is converted to DRI along with the previously heated coal. The material is then discharged directly to the rotary cooler, where it is cooled.
