Hydrocyclones are high throughput and relatively simple devices with a high capacity to size ratio for classifying particles. They are commonly used in a closed circuit with grinding mills, typically ball mills, to control the material size sent for downstream enrichment. The need to
— Recently, the Julius Kruttschnitt Mineral Research Center (JKMRC), University of Queensland has carried out extensive research on the gravity induced stirred mill which includes industrial scale mill performance evaluation. Hydrocyclone operational and design data were collected to evaluate the performance of the hydrocyclone in the stirred ...
— The ball mill-hydrocyclone circuit and the ball mill-screen circuit were sampled in order to measure and compare the performance of the circuits. The ball mills are different in design. Therefore, simulation studies were carried out to eliminate the differences in factors affecting the performance of the circuits such as milling conditions.
— The performance data of hydrocyclones in circuits containing a gravity induced mill (hereafter referred to as a stirred mill) were evaluated to understand their performance in the circuits and the ...
— A hydrocyclone consists of a cylindrical top with an offset feed inlet pipe, an overflow outlet on top and tapered cone(s) leading down to a small outlet on the bottom. Other parts include external casings that contain the internal pressure and are clamped or bolted together, and internal replaceable liners for wear resistance.
— For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure …
The purpose of a mineral comminution circuit with a ball mill running in closed-loop with a hydrocyclone classification battery is to feed the downstream process with the target …
Using the data in Table 1, an example CSE calculation for a typical reverse fed ball mill circuit where 75 μs is the circuit (cyclone overflow) target P80 follows: From the ball mill …
— They observed that the use of shear-resistant flocculants enhanced the hydrocyclone separation performance by decreasing the solids concentration in overflow. In order to use flocculant-assisted hydrocyclones for the mine backfill preparation from mill tailings, Ni [166] selected the flocculant type and the flocculant addition point through ...

— 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 …
— 1. Hydrocyclone grading in the grinding system. The hydrocyclone can be used for the classification of the coarse sand and overflow of the ball mill, as well as the pre-grading before the grinding operation. The obtained process index is almost the same as that of the mechanical classifier, and can basically replace the classifier work.
At each time, the samples were taken from the fresh feed to the mill, ball mill's discharge, hydrocy- clone's overflow, feed and underflow streams using a proper sampling cutter. Figure 1 displays ...
— A state-of-the-art hydrocyclone control system in grinding circuits functions as follows: a coarser mill discharge at higher solids content results in the feed suspension …
Rio Tinto Kennecott has been successful in significantly improving grind circuit performance by implementing real-time closed-loop grind control to enable direct control of the grind …

parallel lines of ball mills operated in closed circuit with either screw classifiers or single- and double-stage hydrocyclones (see Figure 1- Original A.O. Apatit Flowsheet). With hydrocyclone classification, the fine particle overflow from the top of the hydrocyclones was combined with the product from multiple grinding lines
— That means, changing feed properties must be compensated by a hydrocyclone control system, ensuring that the following conditions be achieved: 1. Stabilizing the properties of the hydrocyclone overflow at a constant mill feed rate and fluctuating material hardness. 2. The maximum particle size in the hydrocyclone …
— The role of classification in milling appears to have been neglected in the current efforts to reduce the energy consumption of grinding. Two past approaches, experimental and modelling, for quantifying the effects of classification efficiency and circulating load on the capacity of closed ball mill circuits, are revisited and discussed in …
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- ... technology for monitoring individual hydrocyclone overflow lines for coarse material discharge.

The second CYCLONEtrac OSM system was installed on a trial basis on a single hydrocyclone battery at Minera Centinela in northern Chile with a capacity of 97,000 t/d, which they are in the process of expanding to 105,000 t/d. This concentrator has one SAG mill and two ball mills, each feeding 2 hydrocyclone batteries for a total of 4 batteries.
