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

    A bed disturber is essentially anything affixed to the interior of the kiln to help mix the bed of material. Ideally, the bed of material will tumble and turn over, and thus minimize dead spots or temperature variations in the kiln. Indirect rotary kilns commonly utilize a metal bar as their bed disturber.
