It was determined that the dry grinding of five different feed size fractions of the calcite samples used in the grinding experiments was in accordance with the first-order breakage law for short grinding times (Up to 2 min), i.e., the selection functions (the specific rates of breakage) showed constant normalization depending on the grinding time.

In such a case, you are advised to start with the wet grinding method and then switch to a dry grinding method afterward. The dust extraction system makes the equipment a little more expensive. Parting Shot. Ultimately, the choice between these two methods will largely be driven by personal preferences, budget, time necessity.

The grinding energy obtained during the grinding of Inconel-718 alloy is shown in Fig. 3a. Under dry grinding, the energy consumed was found to be higher than the MQL and flood lubrication conditions (see Fig. 3a). Ogonowski et al. [] reported that dry grinding consumed 15%–50% more energy than flood grinding.The author opinioned that under dry grinding …
