    (pdf) Cements Ground In The Vertical Roller Mill Fulfil

    As less grinding energy is used in producing a cement of a required fineness in a vertical mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. This means that a lower degree of dehydration of the gypsum must be anticipated.Dehydration of natural gypsum and the consequent formation of hemihydrate and anhydrous CaSO4 exerts a significant effect on the cement’s particle size distribution. This effect may be summarized in the following key points • Increasing the amount of natural gypsum determines an almost linear increase of the cement’s Blaine specific surface.

  • Gypsum Content Determination In Portland Cements By

    Cement Milling. Cement milling and gypsum dehydration Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris 2CaSO 4 H 2 O On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4 ).Summary The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 and ball mills have fallen to less than 30 . It is somewhat surprising that the number of different grinding processes and mill types used by the.
