grinding effect of water on gypsum in pulverizer

An experimental study on the ultra-fine grinding of

01/04/2016  As the plaster–water mixture dries, the water will chemically recombine with the hemihydrate gypsum, and the material will revert back to the original composition of gypsum. While the hemihydrate gypsum plaster is in slurry form, it can be poured between two paper and adhesive layers to make wallboard, poured into molds, or used to fill cracks and crevices. Gypsum makes an ideal

The effects of grinding on the properties of Portland ...

01/11/2013  However, this water requirement is not directly related to the filler amount because if we compare, for example the “grinding quality” of different cements and the packing density of dry powder ϕ d, or even of the packing density of normal paste ϕ w, we obtain good fits (semi-logarithmic scales) indicating that the finer the cement, the less it is compacted, and vice versa. Thus, water ...
