Optimization of an industrial scale open circuit three
2016-9-10 Grate discharge single and two-compartment ball mills are widely applied types in cement grinding circuits. The ball mill can have three-compartments and it can be operated in open circuit without using an air classifier in the downstream of the mill. Third compartment of the mill is for fine grinding of cement.

The grinding matrix was calculated using the selection and breakage functions, whereas the classification matrix was defined from the
High pressure grinding rolls (HPGR) applications in
2006-2-1 Tube mills having multichambers are traditionally used for cement grinding either in open or closed circuit operations. In the first chamber, larger balls (100–60 mm) are used for coarse grinding while the smaller balls (40–15 mm) are used for fine grinding. The chambers are separated by an intermediate diaphragm which allows the passage of the fine particles to the second chamber while

Open Circuit Configuration IsaMill™ Advantages
2021-7-4 The product separator is one of the key advantages of the IsaMill™ design. The 8 consecutive grinding chambers, and high tip speed of the separator means that the mill constantly delivers sharp sizing performance. There are no screens or trommels to fail or block, any particle that leaves the mill must escape the same centrifugal forces.

In general, the capacity can be improved by 10%-20% compared with cement mill when these specifications are similar.
cement manufacturing
In open circuit grinding, passage of material is only once through the mill. Consequently, a consistent product fineness is difficult to achieve. Installations having a hydraulic roll press prior to mills are common. In closed circuit grinding, a high efficiency separator (O-Sepa or Sepax, Sepol) is in operation which separates the material

INFLUENCE OF MILL VENTILATION ON GRINDING
The reason why closed-circuit grinding is far more economical than open-circuit grinding is the coarser material in the closed-circuit grinding mill. By ventilation of mills, ground material is drawn out from the mill with the ventilation air, the material remaining in the mill thus becoming coarser, which improves grinding economy.
