Investigation on the ultrafine grinding of coals based on
The ultrafine grinding kinetic model for pulverized coal based on the mechanism of grinding process can be used to predict the particle size distribution of the products in the grinding processThe 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 aBuild an Ultrafine Grinding Mill
