· Stepping from the world of standard milling to highefficiency milling (HEM) can change just about everything. HEM's lower radial depth of cut (RDOC) and a higher axial depth of cut (ADOC) create consistent wear across the end mill cutting edge, generate less heat, and lessen the chance of tool failure. Machines can sustain less stress and tooling can last much longer. Two basic concepts ...
· On the one hand, reduce the grinding amount, on the other hand, recover useful minerals in time, which can improve the grinding efficiency of vertical roller mill. The influence of improving classifiion efficiency on grinding efficiency is selfevident. High classifiion efficiency means that the qualified particle size can be discharged timely and efficiently, while low.
