Two digital properties of flame grade and material grade are obtained by image data analyzing and smooth filtering, which provide reliable reference for operational optimization and automatic control of rotary kilns. This image acquisition system improves the operation of kiln effectively and reduces the working intensity and the manufacture cost %K Rotary kiln %K sintering process %K image processing %K flame analyzing %K monitoring system %U https://journals.sagepub.com/doi/full/10.1177/0142331218810085
