SM at Kennecott Utah Copper Introduction
one SAG mill feeding two ball mills in a closed circuit with a hydrocyclone battery (Figure 1). The aim of the ball mill/ hydrocyclone circuit is to produce the optimum flotation feed particle size while maintaining grind throughput. The optimal operating point is a trade-off between throughput, recovery, and grinding cost.

hydrocyclone
The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds …
