The classifier also have the function of sorting the coexistence, desliming and so on.
Oct 30, 2019· Nanometersized corundum particles for automotive catalysts and particularly stable ceramics can now be produced amazingly easily. ... Home Education Nanoceramics from the ball mill. Nanometersized corundum particles for automotive catalysts and particularly stable ceramics can now be produced amazingly easily.
3 days ago· His team investigated whether a catalytic reaction in such a mill works better because the catalyst is always given a fresh surface where the reactants can meet. They used a soft alumina (gammaalumina) mixed with gold particles as a catalyst and followed the process in the ball mill with various analytical methods.
