Priziwara et al. [13] examined the influences of several grinding aids on particle and bulk properties of ground limestone. They concluded that as the polarity of the grinding aid decreases, the required grinding aid dosage should be higher. It was also reported that the use of grinding aids reduced the surface energy of the limestone.
