Grinding Ball Design - 911 Metallurgist
The softer balls produced a 6% better mill t/h rate but did so at 29% ball consumption penalty. A cost saving solution was found by dosing the daily charge of hard martensitic steel balls with 50% (weight basis) 51 mm (2 in.) martensitic balls to produce seasoned mill ball charge artificially skewed towards the small size end of the spectrum.
Ball Milling | Material Milling, Jet Milling | AVEKA
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...

MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING
In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.
