Calcination of Limestone – IspatGuru

Calcining kilns need limestone with proper decrepitation index. Decrepitation index of limestone is a measure of its susceptibility to disintegration during calcination. Low value of decrepitation decreases the porosity of the bed thus impeding the flow of the gases the kiln efficiency. Rotary kilns also need limestone with good tumbling index.
