Ring formation in lime kilns is a persistent problem in many pulp mills, limiting the kiln production capacity, and in severe cases, resulting in unscheduled kiln shutdown for ring removal. As lime mud/lime solids slide and tumble through the kiln, they cover the refractory brick surface with a layer of dust. The deposited dust

Grinding differs with the pyroprocessing process (kiln type) used. In dry processing, the materials are ground into a powder that can flow in horizontal ball mills or in vertical roller mills. In a ball mill, steelalloy balls are responsible for decreasing the size of the raw material pieces in a rotating cylinder.
