The grinding of each material as obtained from the driers is done in two stages. First, the preliminary grinding, in which the materials are reduced to a fineness of 50 mesh. Ball mills are generally used for preliminary grinding. Second, the fine grinding, in which the size of the materials is reduced to 200 mesh. This is done by grinding in

17/09/2013Raw materials are homogenized by crushing, grinding and blending so that approximately 80% of the raw material pass a No.200 sieve. The mix will be turned into form of slurry by adding 30 – 40% of water. It is then heated to about 2750F (1510C) in horizontal revolving kilns (76-153m length and 3.6-4.8m in diameter.

Homogenization occurs by each species diffusing into the other. In cases where strong chemical reactions occur, the chemical gradients bias diffusion to induce pore formation and swelling. If diffusion rates for the two components are different, then pores form [25]. This is observed in sintering the Ni-Cu system.
