ball mill discharge grind size Grinding & Classification

I am working in a plant with single stage grinding using a ball mill we operate the mill power at around 1400KW& the feed size is 20mm. we use 78mm/64mm steel balls. the ball mill is in closed circuit with classification cyclones. there are 3 cyclones and we operate 2 with a pressure of about 90KPa.

Grinding control strategy on the conventional milling

the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence the control loop will add more water to keep the ratio constant. However, the amount of slurry reporting as fresh feed to the second milling circuit will increase.

Throughput optimisation in milling circuits

The feed rate setpoint can then be tied into a SAG mill power optimisation strategy. SAG mill discharge control is quite involved due to few interactive variables, such as mill discharge sump level, classification hydro-cyclone variables (feed density, flow and pressure) and water feed rate to the sump.

Optimization of mill performance by using

mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners.

Effects of slurry rheology on industrial grinding

Jul 01, 2002· On the other hand, when slurry density increases and fines content reduces, for example, to 78–86% solids by weight (44–58% by volume) and less than 20% passing 38 μm, the slurry is likely to exhibit a pseudoplastic character; examples are primary or secondary grinding mill discharge.

In this configuration, the water addition to the discharge hopper is varied to maintain a constant feed density to the cyclones. The pump speed is modulated to maintain the level in the mill discharge hopper. In a system, if the ore hardness or throughput increases, the achievable grind size increases.
