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 modified Denver flotation machine equipped with a grinding chamber and rotor configuration shown in Figure 1.
mill entry for further grinding. Fine fraction is sent to storage as finished cement. This is the typical arrangement of the so called "close circuit grinding", as described in figure 3. Cement grinding is a continuous process: the clinker/gypsum/additions blend is continuously fed at mill entry and extracted as fine fraction from separator.
