Facing Rotary Kiln Challenges? 4 Solutions to Help You!
2024年5月30日 Solution II: Easily prevent kiln ring formation Ensuring normal rotary kiln flame is one challenge; another is material looping. This occurs when furnace charge adheres in a ring shape to the inner wall of the high-temperature zone. Minor adhesion is termed kiln skin, while thicker adhesion affecting furnace operation is called ring formation.

STUCCO PRODUCTION WITH ROTARY KILNS - Grenzebach
Rotary kilns used for stucco plaster calcining are not brick-lined but are fitted with special durable steel inserts. They distribute the feed of gypsum rock uniformly over the cross-section of the kiln. The rock is thus rearranged several times during each rotation of the kiln. At the same time it moves along the kiln in the same direction as the
