Freeze drying is a dehydration process based on sublimation.To understand the process properly, the best starting point is the phase diagram of water (Fig. 3.1(a)), where the sublimation line is placed at temperatures lower than the water triple point (0.01 °C = 273.16 K) and at vapor pressures below 612 Pa (or 4580 mTorr).Therefore, in order to cross the …

Wet grinding advantageous - requires less power per ton of material ground than dry grinding. Dry grinding consumes more energy because the fine particles adhere to the balls, forming a layer that causes the solids to occasionally slide between the balls without fracture. The disadvantage of wet grinding, however, is that there is more wear.
