requires fewer particles to be in contact with the grinding medium, that is, the roll surface Klymowsky, 2009. There is, however, a negative aspect of particle-bed grinding, namely a retardation effect. Grinding virtually comes to a halt in highly compressed beds at sufficiently high pressure. This was shown by Fuerstenau et al. 1996
