Dynamic classifiers improve pulverizer performance and more

Jul 15, 2007 . Most existing pulverizers—both the vertical-shaft and ball-mill types—come with a static classifier. Its blades reject coarse particles to produce a stream of coal particles that are mostly about 0.0029 inches (74 microns) across. Obviously, not all of the particles leaving the pulverizer are that size. The fineness.
