How A Rotary Kiln Works Powerpoint


Question of the Week: How does a Rotary Kiln Work?

Rotary kilns can be either direct-fired, or indirect-fired (calciners) Direct-fired kilns use direct contact between the material and the process gas to cause the reaction, whereas indirect kilns rely on the heat emanating from the shell of the drum, which is externally heated to temperature
