veying) and in the concentrator plant for the grinding mills and cyclone or slurry pumps. In this paper, we focus on the ore grinding and conveying applications, for which the gearless principle was expanded even further so that the motor and the mill respectively conveyor and pulley were combined in such a way that the motor becomes an inte-
2.1 SAG mill model The particles fed to the mill are ground in the milling chamber and subsequently downloaded into the discharge zone, where, according to a classification probability, they are either returned to the milling chamber for further grinding or become part of the mill output stream. For modelling purposes the mill is divided in two ...

The current world consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110. kWh/tonne, and around 40% of this energy is consumed for clinker grinding.. There is potential to optimise conventional cement …
The physical or empirical modeling of the grinding process and the effects of its parameters on the workpiece quality is sophisticated. This is due to the extreme complexity of the process. So far, no remarkable success could be made by the proposed models to achieve a reliable and effective design and control of the process. This article …
perfect mixing ball mill model were studied. A series of samplings were conducted around the raw mix grinding circuit, and clinker samples were taken. The data obtained from the plant sampling was fitted with the perfect mixing ball mill model using the steady-state mineral processing software, the JKSimmet.
