  • Modeling breakage rates of coarse particles in ball mills

    The non-first-order rates shown in Fig. 1 have often been associated to the fact that at coarser sizes particles are no longer properly nipped between grinding media, with softer particles breaking more readily, leaving tougher particles within the mill charge. This, which is called by Austin a 'material effect', contrasts with an 'environmental effect', …

  • Black Powder Milling Question

    As far as placement of your mill, the ideal distance is probably around 150ft or more away from any buildings of any sort. If you can barricade it that's even better (things like sandbags). Just make sure you don't block off air to the motor. When making black powder there is always a chance for it to go off.
