6. Raw material mill. This takes places in vertical steel mill, which grinds the material through the pressure exerted by three conical rollers. Which roll over a turning milling table. Horizontal mills, inside which the material is pulverized by means of steel balls, are also used in this phase.
This is typically done in a raw mill, a large rotating drum containing steel balls that pulverize the material. Blending: ... Traditional cement production involves the calcination of limestone, which releases a considerable amount of CO2. Additionally, the high energy requirements for heating kilns further increase the carbon footprint.
