Blog: Measuring density in grinding circuits 1/3

2020-3-20 · In this blog you can read there are multiple reasons for measuring density in the grinding circuit. In most sites a ball mill is used for grinding and a (hydro) cyclone for classification. The slurry needs to be continuously monitored and controlled. Density meters efficiently help operators to monitor and control the grinding circuit, optimize it and prevent process failures.

Ball Mill Explained

If a ball mill uses little or no water during grinding, it is a ''dry'' mill. If a ball mill uses water during grinding, it is a ''wet'' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than …

the primary crusher performance and proper control of the ratios for the SAG mill feeders drawing the ore from the stockpile. The ball mill grinding efficiency was poor and could be indicated by the fraction < 125 µm of only 5-9 % or x. P, 80: >400 µm in the mill discharge. This was deemed due

Hydrocyclones

In this case, cyclone underflow is fed to a weired area in the underflow tub, and gravity-circuit feed taken from this area. Slurry excess to the capacity of the gravity circuit overflows back to ball-mill feed. For those circuits treating ball-mill discharge, a sluice can often be arranged to provide some preconcentration for the gravity circuit.
