The sample was dried at a low temperature for two days. Then it was crushed in stages using a jaw crusher and simultaneously screened with a 50 mesh sieve. The resulting coarse fraction was further ground in a roller mill to a minus 50 mesh size. Thereafter, the monodispersed feed sizes required were prepared from the minus 50 mesh material. The grinding tests were carried out using a
