  • Hammermill grinding rate and energy requirements for thin and

    The grinding rates and energy requirements for the ham- mermilling process are influenced by a number of variables. These variables include the characteristics ofthe grains, the. screen, the aspiration system, the hammer type and condi tion, and the feeding method of the hammermill (Kuprits 1967).

    In summary, the particle size range for a specified hammermill screen size can be adjusted through manipulation of the hammer tip speed, which is made possible using motor variable frequency drives. This experiment showed that when using a 6/64, 10/64, and 16/64 in. screen hole diameter, increasing tip speed from 10, 250 to 20,500 ft/min reduced d gw by 233, 258, and 305 microns, respectively.

    A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while material is fed into a feed hopper.
