What is a Rotary Kiln Bed Disturber

Bed disturbers are used in both direct and indirect-fired rotary kilns to promote uniform heating of the material. The bed of material should roll, not slide, throughout the kiln in order to expose fresh material to the process. This rolling action allows for even heat Continue reading →

Indirect Rotary Kiln Cross-flow Configuration

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 Continue reading →
