Coal homogenization - Wikipedia

Worldwide, industry uses bulk material, like coal, as a source of energy or as a raw material for production processes. Intermediate storage facilities (for example stockpiles) are required to decouple the (discontinuous) supply of raw materials from the (continuous) production process. Large quality fluctuations of the material.
