In the grinding process heat will be generated and the cement will be heated up. The temperature of the cement leaving the mill will be dependant on the temperature of the materials (especially the clinker) fed to the mill and to features of the mill and the grinding process. It will typically be in the range from 90 to 120 deg. C.

Cement grinding operation may be performed in one of the following mill setups. Ball and tube mills. Vertical Roller Mills (VRM). Roller press with Ball mill. Ball Mill. Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical ...
transport, ducting arrangement, dampers, etc) o Equipment design including the separator, mill internals such as liners (lifter/classifying), diaphragm (flow control), media, etc o Degree of automation such as fuzzy logic / total feed / sonic control, auto sampling, etc) Energy consideration in cement grinding
applications of the vertical roller mill for cement grinding are less prevalent. The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative

cement clinker, blast furnace slag and pozzolan. Vertical roller mills are one of the core items in cement plants and are used ... Bearing arrangement of grinding rollers Extreme requirements especially on the bearings of the grinding rollers due to very high loads, vibrations
The arrangement design and chosen equipment of the grinding plants are selected according to the type of material to be dried, grain size, and moisture content. Since dried and hot after ・Bshing and classi・…ation, the external material circulation, including the rejects, act as a dilution for moisture when mixed with the fresh feed.
The pressure arrangement of the grinding rolls is hydraulic. The mill feed is introduced into the mill from above, falling centrally upon the grinding plate; then it is thrown by centrifugal force underneath the grinding rollers. A retention ring on the periphery of the grinding table forms the mill feed into a layer called the grinding bed.
