Grinding aids had adverse effect only on quartz grinding, but have significant beneficial effects on grinding limestone and clinker [3]. Jeknavorian and others had identified phenol, 5glycol, and alkanolamine compounds in cement with the test technique they found [4]. Grinding process depends on the control of the agglome
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 raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...
The effect of Grinding Additives is evident in all cases, especially in case of highBlaine CEM I and blended cements (CEM II as well as CEM III, CEM IV and CEM V cement types). The different grinding processes of vertical mills compared to tubular ball mills, have led to the development of a new generation of Cement Grinding Additives.
