Significant turbulent vortexes in the table—roller flow field have been observed and that field is the main gas—solid coupling flow field of the vertical roller mill. With the increase of gas flux, there is a visible increase of velocity and pressure drop in the multi-phase flow field resulting in improved powder transportation.

The working principle of vertical roller mills is relatively simple. In a rotating drum, grinding media (steel balls or ceramic beads) are fed through the mill's inlet, and the particles are ground into smaller sizes by the mechanical forces generated by the motion of the drum. The ground material is then passed through a classifier, which ...
