Question of the Week: What is a Rotary Kiln Bed Disturber?

This article was authored by:

Jenny Seim
Technical Writer

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 →
