    Aug 15, 2020 For some large rotary kilns, the heat load on the lower part of the Kiln Hoods is relatively high. If the general high alumina castable refractory is not well maintained and temperature rise controlled, they are prone to bursting and falling off. The top of the Kiln Hoods is close to the tertiary air duct, and the dust-laden airflow is relatively serious.
