1. Introduction. Grinding aids, first introduced into cement manufacturing in 1930 [], are surface-active substances that facilitate particle comminution during the milling process.In the production of Portland cement, grinding aids are added in small amounts in the range of 0.01 to 0.10% by weight of cement, according to the PN-EN 197-1 standard [].

Grinding of cement clinker and granulated blast furnace slag in roller grinding mills (vertical airswept grinding mills) is a technology introduced by Loesche. The first use of a Loesche mill, with a grinding track diameter of only 1.1 metres, was used as long ago as 1935. However, the breakthrough in grinding this type of material on the vertical

Operation and Elements of a Closed-Circuit Ball Mill System Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber. …

The finish grinding process is the concluding step in cement production and determines the quality of the cement. It involves grinding the cement to an optimal particle size distribution between 3-30 microns to favor the hardening process. Higher fineness over 5000 cm2/g actually lowers strength. Grinding aids are added to facilitate grinding by …
