Ultrafine Grinding
The definition of fine and ultrafine grinding varies, but fine grinding is often considered to take place below P 80 values (the size that 80 wt% of particles pass below) of 100 μm [7] and ultrafine grinding below P 80 values of 20 μm [8] with lower size limits of several μm [9].
