    Particles are accelerated to extremely relativistic energies and made to collide with other particles, producing totally new species of particles. Patterns in the characteristics of these previously unknown particles hint at a basic substructure for all matter. These particles and some of their characteristics will be covered in Particle Physics.

    Oversize particles, not easily broken, drop through the mill and may be recycled 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. Attrition Mills. Attrition mills use the hammermill principle to a certain extent;, shattering by ...

  • Ball Mill Critical Speed

    Ball Mill Critical Speed

     · A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula. The mill speed is typically defined as the percent of the Theoretical ...

    Explain that the little balls represent the particles of a solid, in this case the atoms in a metal. Although atoms and molecules are different, this same simple model of balls is used for both. Let students know that for now, they will use circles or spheres to represent atoms and molecules, but eventually they will use a more detailed model.
