Grindability - an overview ScienceDirect Topics

As the HGI ball mill works on the same principle as pulverizing mills, the index obtained from this could give a fair assessment of the grinding capability of torrefied biomass. For biomass, one should use ( Agus and Waters, 1971; Joshi, 1979 Agus and Waters, 1971 Joshi, 1979 ) a standard volume of sample instead of mass to compare the grinding ease to coal and torrefied biomass.

The Jet Pulverizer Company How Jet Mills Work :

The Operating Principal. P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process material itself.
