Cement Kilns: Size Reduction and Grinding

2019-5-20  Cement specifications clearly needed a way of prescribing the fineness of cement, and the sieve method was written into standards in the absence of any more useful measure, despite the fact that it provided little guidance as to the likely quality of the cement, particularly as the number of different grinding technologies multiplied.

Progress with grinding aids for VRMs Global Cement

2021-2-23  Grinding aids for VRMs increase the powder flowability of the finished cement without reduction of the stability of the material bed. The impact of grinding aids depends strongly on the fineness of the cement: The higher the surface area, the bigger the attraction force and therefore the bigger the benefit from an appropriate grinding aid.
