  • Hammer mills : an engineering overview. What is it ? How it works

    The hammer mill design is very robust and is used in many appliions, from grain milling to heavy duty requirements such as rock crushing or waste grinding. Hammer mills are part of the impact mill family, which means that the milling effect is obtained thanks to the speed at which particles are impacted, here, by one or several rotors. 2.

  • Ball milling

    A ball mill is simply a container that is filled with pebbles (either of porcelain or stones Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them. Ball mills can be continuous or periodic, they can be small or gigantic, low speed ...
