“The three authors from Metcom Technologies are highly regarded contributors to the field of comminution efficiency, last year publishing (along with Jim Finch) a paper on ball mill classification system optimisation that was Highly Commended by the CEEC Medal judges,” CEEC said.
Mar 10, 2013 The rod mill is almost an obsolete device, and I asked the question at Comminution ’12 whether ball mills would play a significant role in comminution circuits, or would they be superseded by SAG mills.Chris Rule, of Anglo Platinum felt that rod mills will play an insignificant role, as they are severely limited in terms of size, and ball mills may play a diminishing role as the upper feed

The sample is staged crushed to 100% passing 3.35 mm. The crushed feed sample is subject to a grinding by a standard ball mill. The BBWi is calculated after achieving a consistent IPP of ~28%.
use of HPGR for hard rock multi-stage crushing and ball mill circuits at high tonnage rates (Parker et al, 2001). Table 2 provides a simple comparison of the various comminution circuits.
Meanwhile, the ore hardness has increased by 13 per cent to a Bond work index value of 15 kWh/t that led to a coarser flotation feed. Karara Mine has decided to shift the comminution workload from the primary ball mill to the TowerMill circuit by bypassing the 100 m fine screen in between the ball mill and TowerMill circuits.
Grinding is probably the single unit operation that requires the largest capital investment and operating costs in an ore beneficiation plant. Because of that, a great deal of research has been concentrated in the theory, design and operation of grinding equipment, in particular ball mills. To-date, the models developed to describe grinding in tubular mills.

Comminution 2019, which is an early meeting in what is planned to become a series, will necessarily be restricted to a limited range of topics, suffice it to write that it will be concerned with the breakage of coarse rocks and their progeny in SAG mills, of smaller pebbles in HPGRs, and of finer particles in vibrating and tumbling ball mills
Synopsis. A number of modern techniques suitable for the design of crushing and grinding circuits are described. The methods are based on extensive use of mathematical models of crushers, mills and classifiers and are seen as alternatives to conventional comminution design methods based on Work Indexcalculations.

Ball mill wave liners wave liners and the further refinements to high-low, single and double wave liners all are custom designed for each ball mill. Evaluation of the wear profile experienced in the mill directs the design with the intent being a more efficient grinding action and a more consistent wear profile throughout the liners life.

The parameter M i takes on different values depending on the comminution machine: M ia for primary tumbling mills (AG/SAG mills) that applies above 750 μm; M ib for secondary tumbling mills (e.g., ball mills) that applies below 750 μm; M ic for conventional crushers; and M ih for HPGRs. The values for M ia, M ic, and M ih were developed using the SMC Test combined with a database of
