Designed to provide an efficient means for continuously processing granular materials and powders at high temperatures in oxidizing, inert or reducing environments, rotary calciner consists of a cylindrical rotating tube housed in a refractory-lined gas or electric furnace, positively sealed to prevent air infiltration.

Line includes rotary dryers, coolers, kilns, calciners and combination dryer-coolers.

A number of plausible mechanisms can explain kiln and dryer vibrations. The company explains eight common reasons and offers recommendations in a white paper on its website.

As is true with most mechanical equipment, not all dryers and kilns are created equal. Perhaps even more dramatic is how the design of flighting systems — the fins or baffles installed inside dryer drums to direct airflow and product within the dryer and optimize drying — have changed over time.
