Oct 05, 2016 Ball mill closed circuit Ball mill + HPGR pre-grinding closed circuit The efficiency of a two-compartment ball mill is defined to be 1.0. This efficiency reflects the power consumption of the mill only and does not include any auxiliary equipment like conveyors and dust collectors nor the separator. 3. Conclusions.3. INEFFICIENT OPERATION OF BALL MILL Efficiency of a closed grinding circuit is related to two parameters breakage efficiency and classification efficiency. In other words, ore should be ground to a desired size and removed from the circuit. So the overall efficiency of a grinding circuit equals to breakage efficiency multiplied by.

This paper discusses the process selection of single stage mills, the design flexibility Classification efficiency can also affect the result. Achieving a coarse grind from a even with a high ball charge or mill speed, the circuit selection may be incorrect. If a recycle crusher was not included it should be trialled. If included, the.For ball mills operating in closed circuit, the circulation load is monitored by weighing the flow of reject material from the separator. These measures ensure you achieve optimum mill performance, giving you the quality, efficiency, safety and reliability that you need.

Compared to those from the ball mill circuit. This has often resulted in conclusions concerning lower energy efficiencies of AG SAG mill circuits compared to ball mills. The correlation between the AG SAG and ball mill circuit data is also very poor. Use of equation 2 shows a very different picture, the results being illustrated in Figure 7.Milling circuit consists of a rod mill followed 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.
