In reality, the term grinding is misleading.

Best Wheel For General Dry Grinding - Practical Machinist

Many years ago it was the first choice for dry grinding due to its rapid breakdown and the resulting sharp fractured remaining grain. The pressure that is exerted on the grain increases as the grain surface becomes dull. The grinding wheel tends to be self sharpening assuming that it also has a low grain bonding strength.

Pelletizing Process

A wet grinding system (Fig. 3) accompanies a dewatering unit with a thickener and filter, while a dry grinding system (Fig. 4) requires a prewetting unit. Drying is usually provided in association with dry grinding. Prewetting includes adding an adequate amount of water homogeneously into the dry-ground material to prepare pre-wetted material

COMPARISON OF WET AND DRY STIRRED MEDIA MILLING …

147 nm. The lowest median size in case of dry grinding was 1.88 µm. At all specific grinding work the dry grinding resulted in higher median particle sizes than the wet one. The 6 and 10 m/s rotor velocities and thus the different stress energies showed significant effect in the median particle size in the measured range.
