Particle size reduction (Arno Hahma)

You can grind it with whatever suitable mill just make sure the mill is clean before you start AP can be detonated with a very powerful shock so a ball or a hammer mill is not recommended for that totally unsuitable and if so what method _should_ be used to achieve size reduction of materials in the 2000um range down to the 300um range

Wind Turbine Concepts Defined and Explained

Besides having to withstand vibration and high rotation speed there is a significant amount of thrust back on the bearings from the wind and it increases geometrically as the prop size increases That's why we've moved to using standard trailer wheel bearings in our designs they are tapered and designed to take the thrust loads

Rod mills how they function

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded For an equivalent grind a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore The rod charge must be maintained in good working condition and broken and worn rods must be removed
