The coal mill pulverizer plays a crucial role in this process. Significance of Coal Mill Pulverizer: The function of a coal mill pulverizer is to turn the coal into a powder form by using the coal as fuel. The pulverizer is mainly responsible for grinding the coal into a fine powder, which allows it to be burned more efficiently in the boiler.

Process. Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
