Such a step would require the use of dry rather than wet grinding systems. Traditionally, dry grinding systems have been only an exception in mineral processing, since most post grinding processes are wet. However, there are successful - mainly ball mill based - dry grinding examples in gold, nickel or iron ore. Experience from some of …

Wet grinding is a process that involves dispersing the raw material in a liquid and circulating it through a grinding chamber. The particles are crushed by the grinding media, which are usually small balls or beads made of ceramic, metal, or other materials. Wet grinding can achieve very fine particle sizes but requires more energy, …

Easybuy4u/Getty Images. With dry-brining, you don't even need to wash the salt off at the end of the process, because the salt also has the added effect of pulling moisture to the surface and creating a crispier skin. There's also the obvious fact that dry-brining is significantly less hassle and takes up less space than wet-brining.
