What temperatures do rotary kilns typically operate at? The temperature(s) at which a rotary kiln operates is specific to the reaction requirements of the material being processed and therefore differs in every setting. In general, however, rotary kilns can process material at temperatures ranging from 800 to 3000°F (430 to 1650°C).

How Rotary Trommels Work. As the cylindrical drum of a Rotary Trommel Screen rotates, raw feed material is lifted on shelves until it nears the top of the drum. Material then falls, tumbling onto other material at the bottom of the drum. This action helps to break down softer fractions, as well as separate different types of materials.
