WhatsApp: +86 18203695377These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a singlestage milling application to a semi autogenous ballmillcrushing circuit, and the application is well described. This refers to highaspect AG/SAG mills. Ball Charge Motion inside a SAG Mill. With a higher density mill charge.
WhatsApp: +86 18203695377In ball mill operations, it is always helpful to optimise the grinding media system to minimize the costs of the operation. In a research done by Yu et al. [16] to optimize grinding media system, there was a 30% ... for crushing large particles by impact due to their point of contact between the grinding media and the ore. Spherical
