Fine grinding abrasive materials is typically needed to create particle sizes in the minus 50 mesh range 297 microns down to about 95 minus 325 mesh 45 microns. some of these sizes are typically referred to as talc, flour, pulverized, or ball-mill fine grades.
Particle size distribution vs. hiding strength. particle size is directly related to hiding power in pigments. due to its speed and wide size measurement range, laser diffraction is an ideal tool for tracking the grinding process and therefore controlling the resulting pigment performance.
