with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent. The twocompartment ball mill operating in a closed circuit with a high efficiency

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)".

Closedcircuit tumbling ball mills with dynamic air classifiers have been commonly operated as cement mills [1], [2], [3]. Fig. 1 shows a process flow diagram of a closedcircuit, twocompartment ball mill with an air classifier. Twocompartment mills with an intermediate diaphragm provide the flexibility to use different mixtures of ball sizes in each milling compartment.

When only the HPRM system or the ball mill system was operated to produce cements of the same fineness as the combined process cement, the system throughput was reduced to t/h in the HPRMonly case and to t/h in the ballmillonly case, with the corresponding specific energy consumptions of kWh/t and kWh/t. The works ...

The mill is filled with fresh and coarse material. After grinding, the material is split by an air separator into new coarse material and the finished product. Since direct measurements inside a cement ball mill are hardly possible, the grain size of the material, a crucial parameter, has to be determined offline.

Depending on the desired properties of the cement being produced, additional additives such as power station fly ash or blast furnace slag are also added to the cement mill infeed. Typically, ball/tube mills have dominated cement milling; however, some application of vertical spindle (roller) mills has occurred in recent years.
