Due to the constraints in the production process of mining system, the raw materials used in the lime kiln are sometimes insufficient. By expanding the particle size range of the raw materials, the most suitable raw material particle size ratio is found. Practice of grading calcination is applied on the two production lines to ensure the yield and quality of the lime kiln, receiving better results.
