Rotary kilns are considered to be better than vertical shaft kilns

One critical factor in designing a rotary kiln is the air flow configuration, or the direction in which the process gas flows through the kiln in relation to the material. Rotary Kiln Air Flow Configurations. Rotary kilns are available in two types of air flow configurations: co-current and counter current
