The ATOX® raw mill uses pressure and shear generated between the rollers and the rotating table to crush and grind raw materials. Feed material is directed onto the grinding table by the feed chute. The rotation of the grinding table accelerates the material towards the grinding track and passes it under the rollers.
The classifier plate (5) separates the finely ground product for exit through the discharge outlet (6) while returning oversize material back to the mill inlet through the recycle housing (7). Air Impact Pulverizer In air impact pulverizers, superheated steam or compressed air produces the force that reduces the size of large particles.

The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball …
the raw meal quality in the kiln feed as much stable as possible is of high importance. The variation of this parameter is related to the homogeneity of the raw materials in the raw mill (RM) inlet, to the mixing efficiency of the homogenizing silo and to the regulation effectiveness as well.

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect …
