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

2021-8-16  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.

A data-driven decision-making framework for online

Abstract Vertical roller mill (VRM) is a large-scale grinding equipment, which is used to grind raw materials from block/granule into powder. Due to harsh production environment and inconsistent raw material quality, VRM requires timely regulation. Currently, the regulation of VRM is manually conducted; operators make decisions based on their observation and experience, therefore the
