Residue of cement in open circuit mill. We have a cement mill,2.4m dia 7.9m length with 3 comp. The residue in 90 microns is always fluctuate from 3 to 7 % for same feed rate and same composition and same air vent quantity.
In continuous open-circuit ball milling, feed material is continuously fed into the inlet of a mill and it is ground by grinding balls (see Fig. 1). Ball motion is initiated by the rotation of the shell, and the axial transport of the cement clinker particles is carried by the air stream and dispersion caused by ballâ€"particle collisions.
In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of the cement.
