After temporary storage and reasonable compatibility, hazardous waste enters the rotary kiln through different feeding methods, such as grab buckets, elevators, and conveying pumps. Under the continuous rotation of the rotary kiln, waste goes through the drying, incineration, and embers sections successively.

Some aspects of plant operation that help kiln performance are kiln feed size, homogeneity, kiln time/temperature profile, heat balance, and volatile and dust cycles; these are discussed in the following sections.
The formed slagging ring will be continually expanded in the case of a low rotary kiln speed and material accumulation, which will cause shrinkage of the effective flow area and reduction of the hazardous waste throughput. In severe cases, the materials cannot flow to the end of the kiln, resulting in the shutdown of the rotary kiln.
