Parallel HydroCyclone Simulation

2019-7-2  The rod mill discharges to a sump, where the slurry joins with slurry that discharges from a ball mill in closed circuit with two Krebs 20″ cyclones in parallel. The contents of the sump are pumped to the cyclones. Cyclone underflow slurries are recycled to the ball mill, while overflow slurries

How to resolve the most common hydrocyclone problems

2020-7-23  The grinding mill might be the issue. Of course, the hydrocyclone isn’t the only place to look when you are reviewing the classification of your grinding mill circuit.. Often when we’re investigating a mill circuit, there are cases where the amount of new feed to the plant has exceeded the ability of the mill to grind the ore fine enough to allow the cyclones

2021-8-12  The discharge from the SAG mill is sent to the ball mill circuit. The mill circuit is arranged with hydro-cyclones in closed circuit and comprises a gravity separation circuit, which recovers and concentrate any gravity recoverable gold. The remaining gold is extracted in a conventional carbon-in-leach (CIL) circuit.

Circuit Control Improvement Orway IQ

A leading Australian nickel mine has a grinding circuit comprising a primary single stage SAG mill in closed circuit with cyclones. The SAG cyclone underflow passes through a flash flotation before returning to the SAG mill. A portion of the flash flotation tails reports to a separate ball mill which helps to reduce load on the SAG mill.
