Figure 2.3.18. Ball mill in operation at a cement plant. The mill shell was protected against wear by liner plates bolted to it. A more recent development has been the introduction of "classifying liners" designed to aid the small balls in migrating toward the discharge end and the bigger ones toward the feed end.
The installation of liners. Length Diameter Ratio. The length-diameter ratio of the cement ball mill is relatively large. For mills of open-circuit grinding system, the length-diameter ratio is usually between 3.5 and 6 to ensure that the product fineness is qualified through single grinding; For ball mills in closed-circuit grind system, in order to increase the material …
The cement roller press is a type of material-crushing machine which is often used in cement plants. It usually works together with a ball mill to form a pre-grinding or final-grinding system for the grinding of raw materials, coal, and clinker.. Compared with the traditional tube mill and ball mill, the roller press has lower energy consumption and …
