As a result of the introduction of ceramic based metal matrix composite technology in the Indian pulverised coalfired power generation market all vertical spindle roller mills in this market, with the exception of E mills, have converted the grinding elements to these products such as Xwin and Neox.
The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.
Shredding, Grinding, or Granulating – Which is right for me? Often, the terms grinder, shredder, and granulator are used interchangeably. So what is the difference and why does it matter? Perhaps the best way to approach this is to answer the "why does it matter?" question first.
