Reduction of Production Costs by Using Alternative Fuels and Energy-Saving Mills

摘要

The article gives a detailed description of the design and specific features of operating the vertical roller mills used for grinding of solid fuels, including waste. A good deal of attention is devoted to the operational safety measures and to the methods of reducing the surface wear of grinding bodies and their replacement. Demonstrated are the advantages of vertical roller mills over other grinding devices, and data are provided to show that rollers mills have practically taken over the entire raw-material and fuel grinding. They are also rather widely used to grind cement and its ingredients.
