The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80% passing 150 µm. Several large tonnage copper porphyry plants in Chile use an open-circuit SAG configuration where the pebble crusher product is directed to the ball mills (SABC-B circuit).

Cyclone underflow is recycled and becomes ball mill feed, whiles the cyclone overflow, consisting of slurry at 80 percent passing 212 microns, becomes feed to 3 banks of rougher flotation cells. Some cyclone underflow product goes to four Knelson concentrators through the Knelson vibrating screen for recovering the minus 3 mm free gold from the feed.

The cyclone underflow is directed to the ball mill- for further grinding. Once the ore has passed through this mill it will be added back into the material that is being pumped to the cyclone for reclassification. The hydrocyclone product is the overflow, which of course is finely ground rock. It is this overflow which must be controlled.

waste disposal. Our KREBS hydrocyclones use gMAX cyclone technology and they are an ideal solution for each of the three steps in this system. In the limestone grinding circuit the ball mill limestone discharges to hydrocyclones for classification. The overflow reports to reagent storage and the underflow returns to the mill for further grinding.

Ball mill. Mean residence time 7 minutes. Overflow discharge with no overfilling and no post classification. 70% solids in the mill. Cyclones. 38 cm diameter "standard" geometry with 10 cyclones in the cluster. Sufficient water should be added to the sump to make the cyclone feed 45% solids by weight. The circuit is standard with ...

Using the large diameter cyclone size, such as the 900 mm diameter, results in a fewer number of operating cyclones and possibly a lower capital cost. The 900 mm hydrocyclone can also produce an increase in the amount of +150 micron material reporting to the hydrocyclone overflow, and a decrease in the amount of -75 micron material in the cyclone underflow product.

HDPE cyclone overflow elbows . The Multotec Cyclone Division has successfully implemented a process that allows us to completely rubber line HDPE overflow elbows. This process was explored due to the ongoing need to extend the overall operating life of HDPE overflow elbows, especially for aggressive milling applications.

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 to generate …

A classifying cyclone system is needed to achieve a 150 micron (100 mesh) separation. The total volumetric flow rate to the system is 5000 gpm at a solids content of 5% by weight (Ï p=1.02). At an average relative solids density of 1.3, the solids mass flow rate equates to 64 tons/hr.

We control the density by adding water to the feed box or usually pump pressure adjustment. Cyclone overflows gravitates straight on to the flotation roughers. Yes I am saying that at higher densities like 37slurry pulp density Vs 7 (+150um sieve density), you get P80 of 85%.

Mill circuit cyclones from Multotec maximise mill efficiency and reduce the energy per ton required.This is achieved via their unique inlet design and, additionally, the cyclone configuration can be altered to accommodate changing operational conditions.. Improved mill capacity by this cyclone, part of Multotec's range of classification cyclones, facilitates increased throughput.

trips through a grinding mill. Researchers have found that, during milling, gold is actually smeared onto other particles and flattened into shapes likely to report to cyclone overflow upon discharge. Gold like this is much more difficult to recover gravimmetrically than if it occurs as a three dimensional particle with a relatively large mass.

mill achieved with MillStar's Segregated Ore Feed Controller combined with the Power Optimiser: • The standard deviation of the mill feed control is greatly reduced. • The cyclone feed is more stable, allowing for consistent size separation and feed to downstream processes. Due to the tighter control the feed setpoint can now be set closer

that the gradient of the ball mill cyclone overflow is similar from plant to plant and is of the order of 0.5, a phenomenon observed by Bond (1961). Similarly most plant data show that where the AG/SAG mill is in closed circuit with cyclones (or very fine screens such as DSM screens) its product is also similar in shape
