CGA acts on stabilizing thegrindingbed in theVerticalRoller Mills. At same time, CGA prevents air entrainment in the bed, thus reducing drastically mill vibrations. Furthermore, due to the addition of CGA, the amount of water required to achieve this effect is much lower – Results in improved strengths performance & requires lesser heat ...
Dec 01, 2019· Thereby, thegrinding aid effectswere found to be very solid-specific. For the finegrindingof limestone, slag sand and quartz, the addition of comparatively high amounts of heptanoic acid caused the most pronounced stabilization effects. Generally, thegrinding aid effectswere lower in the case of quartz in comparison to the other materials.
