5 minutes agoIndian shares were set to open a tad higher on Thursday after logging losses in the last three sessions, but caution prevailed as quarterly earnings trickle in, amid weak global cues.
As discussed in the literature [1,2,4], there was significant effect of using grinding aid in cement grinding. Grinding aids are active surface agents that counteract the agglomeration of very fine particles on the grinding media, thus inhibiting the grinding effect and therefore reducing production rates. A number of grinding aids ar e ...

Grinding of clinker consumes power in the range of 2.5 kWh/ton of clinker produced. These and other pyroprocessing parameters make cement production costly. The pyroprocessing process in kilns and the grinding technologies therefore have to be optimized for best processing. This paper discusses the cement manufacturing and …

Major phases present in unhydrated Portland cement are alite (Ca 3 SiO 5 -tricalcium silicate), belite (Ca 2 SiO 4 – β-dicalcium silicate), aluminate (Ca 3 Al 2 O 6 - tricalcium aluminate), ferrite (Ca 4 (Al, Fe) 2 O 7 – tetracalcium aluminoferrite). Table 15.1 shows the compositions and abbreviations of these compounds. Table 15.1.
