Limestone is excavated from open cast mines after drilling and blasting. Bigger limestone pieces are shifted and crushed to reduce the particle size to below 50mm. The crushed materials are stacked and transported to closed conveyor belts for analysis using Gamma Ray spectroscopy. Pre-blends are achieved by systematic stacking in the ratio of 10:1.
