Different machines to meet all needs
addition, grinding increases the surface area of the solid and thus increases its suscep-tibility to reaction with the atmosphere. For example, it has been observed that the iron(II) content of a rock may be decreased by as much as 40% during grinding— apparently a direct result of the iron being oxidized to .

Within the sieve mill, the grinding is achieved by the material impacting the grinding tools mounted to the grinding disc. The grinding disc rotates around the grinding track, which includes the sieve itself. The sieve acts like a classifier as it determines the particle size according to its hole diameter.

Some of the things that you can inhale when grinding won't be absorbed, some will. I believe a minor amount of iron can be absorbed, but things like silica and carbon won't. Silica causes silicosis, carbon causes black lung. They add up over time, so you don't have to grind week in and week out... each time you grind more gets added.
