Intermediate and fine size reduction by grinding is frequently achieved in a ball mill in which the length of the cylindrical shell is usually 1 to 1.5 times the shell diameter. Ball mills of greater length are termed "tube mills," and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as "pebble mills.''''

· Jake_G. another_jim wrote: Fines amount to only 2% to 3% of the total mass, rising only slightly, and continuously, as the grind is made finer. But each fine particle has roughly 1000th to 100th the mass of the regular particles, so there''s lots of them to fill in the gaps between the coarse particles.
