1. What is a Vertical Grinding Mill? The Vertical Grinding Mill (VGM) is an upright steel vessel with an inlet, an outlet and a central portion of the inlet. It is used for fine size reduction when output to input reduction required is large. These mill crushers consist of a reducing rotating mill for size reduction.

Indeed, according to Boulvin et al. [44], experimental data from a grinding circuit show that mill throughput impacts the separating curve. A recent experimental study on parameters affecting the VRM performance shows a correlation between product fineness and dynamic separator speed, mill throughput, and the rollers hydraulic pressure applied to the grinding table of the VRM [45].

Vertical Milling Machines. In vertical mills, the spindle axis is vertically oriented. Milling cutters are held in the spindle and rotate on its axis. Typically the spindle can be extended or the table raised or lowered to produce the same effect, allowing for plunge cuts and drilling. The two kinds of vertical mills are bed mills and turret mills.
