Abstract
In a pulverizer of the type having, within a casing, a stator and a rotor to be rotated in the stator, both having large numbers of mutually confronting ridges or teeth with a gap therebetween, the gap is 1 mm or less, and the ridges of the stator are of sawtooth shape as viewed in cross section and have flanks forming troughs therebetween with an acute bottom dihedral angle of 45 to 60 degrees. At least one tier of a classification ring is provided around the inner wall surface of the stator to form flow-blocking barriers across some or all of the troughs thereby to prevent particles being pulverized from being swept through the troughs without being satisfactorily pulverized.
