In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named "conscious laboratory (CL)". For constructing the CL, a ...

Fig. 2 shows the timewise evolution of the cumulative PSD experimentally obtained from the laboratory batch ball mill with different single ball sizes (, d B = 20, 30, and 40 mm) using steel balls and alumina balls. As milling progressed and finer particles were generated by breakage, the PSD shifted to the left monotonically even in the fine particle size domain (1100 μm).
the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential features of a model for mill power.
The best ball mills, however, enable you to achieve the desired product quality quickly and e ciently, with minimum energy expenditure. That's what the FLSmidth ball mill is designed to do with the added benefit of high flexibility. You decide whether to operate the mill in open or closed circuit, with or without a pregrinder.
