    Over-size particles, not easily broken, drop through the mill and may be re-cycled or discarded. Thus foreign materials, such as metal and stones, are discharged before they are forced through the screen causing damage. Fig. 1 Hammer Mill. 2.2 Attrition Mills. Attrition mills use the hammermill principle to a certain extent; i.e., shattering by/impact.

    You could run a hand calculation on your diaphragm to get an idea of what the stresses might be and compare those stresses to the modulus of rupture. Alternatively, you could envelope the stiffness and run the model twice: once with 0.35Ig and once with 0.7Ig.

  • Grinding in Ball Mills: Modeling and Process Control

    The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The
