A third ball mill takes a split of feed from each module to assist maintaining a target product size. Both modules are fed from the same primary crushing circuit via a Coarse Ore Stockpile (COS) which provides surge capacity. The grinding circuit is designed to produce a product size suitable for the downstream froth flotation process. User Story There are multiple factors that can affect mill ...

by a ball mill in series. Crusher product (9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone (Cylcone 1). See Figure 1 for a schematic of the process flow. The ...

Increasing pulp density in a certain condition, the viscosity of ore pulp will strengthen, making it easier to adhere to ball mills, thus enhance the mill productivity to improve the grinding outcome. But when the pulp density is too high, the ropy ore slurry will have buffer action on ball mills grinding operation. Higher feeding speed can contribute to timely ore discharge, while excessively ...

Lloyd Sponenburgh, in his Ball Milling Theory and Practice for the Amateur Pyrotechnician, tells us his explorations into ball milling began when he was faced with having to do all that grinding with a mortar and pestle to achieve small particle size and intimately mix his chemicals. Lloyds's book is the most complete and practical resource I know for information on ball milling theory and for ...

The grinding plant can also be equipped with a ball mill following the POLYCOM. This is called a combigrinding circuit. The main feature of such a system is the pregrinding of cement clinker in the POLYCOM and a final grinding in the ball mill. The specific power consumption compared to a ball mill cement grinding is significantly lower and additionally paired with a 30 to 40 per cent ...

grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe, light emitting diode, phototransistor and video photographs were used to determine the load orientation in terms of toe and shoulder positions. A load beam ...
