• Ball Mill Explained

    A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders a rod mill. Ball mills are usually either of the ...

  • The Mechanism and Grinding Limit of Planetary Ball Millingt

    the planetary ball mill consists of compressive, abrasive and shear stress of the balls, which is believed to be effective in producing very fine particles. About thirty percent of ball filling of the mill was found to be the optimum. This was explained by an analysis of the motion of the balls and the measurement of the contact force. It was found that the grinding limit is greatly .

    Size reduction increases as the number of rotations and time taken for ball milling increases. Meshes of larger aperture should be used in sieving to obtain a complete curve of particle size distribution. Some particles were lost when transferring them out of the ball milling, which results in lighter weight obtained after ball milling. Experimental result reported showed that the grinding ...
