Whether you are using a rotary dryer, rotary kiln, or rotary cooler, there is one thing that all these instruments have in common: they all use methods of heat transfer to carry out their jobs.Heat transfer is how heat moves from one source to another. Understanding the types of heat transfer, and how they differ, is an important part in understanding how a rotary dryer, cooler, or kiln works.

The heat transfer mechanism in rotary kilns includes conduction, convection and radiation. Figure 1 shows an indirectly heated rotary kiln. As the rotary drum wall, which is usually made of steel or graphite, is heated externally with Q total, heat from the source is transported to the wall and then conducted through the wall Q W

heat transfer calculations useful for estimating the effects of kiln design and operation on burden temperature. This pa-per presents a mathematical model of heat transfer in direct- ly-fired rotary kilns. The model uses one-dimensional zon-ing along the kiln axis with a mean beam length radiation model.

The rotary kiln provides constant mixing of the pellets, bringing all the pellets to the same temperature. In a straight grate, the pellets at the top of the bed are “over cooked” and those at the bottom are “under cooked”. Higher quality means fewer fines, better reducibility and less variation in compression strength.

Heat exchange in a rotary kiln may be by conduction, convection and radiation, in descending order of efficiency. In low-temperature processes, and in the cooler parts of long kilns lacking preheaters, the kiln is often furnished with internal heat exchangers to encourage heat exchange between the gas and the feed. These may consist of scoops or "lifters" that cascade the feed through the gas ...
