An important consideration in rotary kiln design is air flow, or the direction in which the process gas moves through the kiln in relation to the material.
The cross-flow configuration is specific to indirect-fired rotary kilns. Here, the material and the process gas flow perpendicular to one another, as opposed to co-current or counter-current flows.
The advantage of the cross-flow configuration is that the material can be held at a constant temperature for an extended period of time, a process difficult to achieve in co-current or counter-current kilns.
Understanding air flow configuration, including the available options and benefits of each, is an important consideration in rotary kiln design.
