The power ingesting of a grinding process is 5060% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
mill commonly found. Grinding mills Ball mills Ball mills vary in their details and size but the basic design consists of a horizontal hollow cylinder, with an abrasionresistant interior, that rotates about its central axis. The grinding is performed by stone, metal or rubber balls .

Univariate regression. After choosing the regressor variables, the structure of the model should be selected. Cost models of mineral grinding mills have historically applied the power function platform (Mular, 1982, Mular and Poulin, 1998; Pascoe, 1992).In these models, the mill power has been selected as the explanatory variable.

To prevent ore from wearing out grinding mill drums, replaceable liners are inserted. ABB and Bern University of Applied Science have developed a liner wear monitoring system based on accelerometers and machine learning that identifies the best time to change the liner and thus reduce downtime costs.
mill is the energy consumption. The power supplied to 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 ...
