2018-3-29  Grinding aids act by coating the particles which cause agglomeration with a mono-molecular film which neutralizes the surface electrical charges. Technically speaking, grinding aids provide the charge carriers necessary to satisfy the charges originated by the fracture of the clinker during grinding, thus reducing the tendency to agglomeration. Grinding aids are adsorbed at the fractures surfaces of
