Identifying the apparent and true grinding limit

by laser diffraction and in the case of smaller particles (b1µm)by Dynamic Light Scattering (DLS). In most grinding experiments it is observed that after a certain milling time no further decrease of the particle size occurs and a plateau in particle size is reached. Fig. 2 illustrates the development of the particle size of quartz
