  • Coal Mill Safety

    VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is capable of making a system that conforms to these and is therefore safe. However, this is not the case.

  • Coal Mill in Cement Plant | Vertical Roller Mill & Air-Swept

    The most used coal mills in cement plants are air-swept ball mill and vertical roller mill. At present, most cement plants use coal as the main fuel in the clinker production process. The standard coal consumed by the new dry process for producing 1 ton of cement clinker is usually between 100 kg and 130 kg, and the fuel cost accounts for about 15% of the cement production cost.
