Vertical roller mill optimisation CemNet

2017-4-5  Vertical roller mills (VRMs) have become the equipment of choice for raw and solid fuel grinding in cement factories. Increasingly modern cement plants also use VRMs for cement grinding. However, opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding, drying, classification and regrinding take place within the body of the mill.

Research of iron ore grinding in a vertical-roller-mill

The total energy consumption for ore comminution will further increase within the next decades. One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle.

Operational parameters affecting the vertical roller

2017-4-1  Mineralogical analysis is a good way to evaluate the effect of vertical-roller-mill on downstream processes. For this specific ore the degree of mineral liberation is still to be determined. In previous works ( van Drunick et al., 2010 ) an increase in the degree of mineral liberation by the usage of the VRM compared to conventional technologies could be proven.

[PDF] Modeling and simulation of vertical roller mill

There are few studies concerning the process simulation of vertical roller mills (VRMs). In this research work, the application of population balance model for simulation of a VRM in a cement clinker grinding circuit was investigated. The residence time distribution (RTD) was measured, and the tank-in-series and Weller models were employed to describe the residence time distribution.
