The testing was conducted in a large copper ore mine which had a SAG mill in a closed circuit with the cyclone cluster. The trial tested one Cavex 2 650 in a sixplace cluster of existing Cavex cyclones and saw an improvement of up to % in circulating load and % in water bypass versus the original cluster, according to Weir Minerals.
When you add water to the feed of the cyclone, the result is the overflow becomes lighter and the underflow becomes heavier. The heavier UNDERFLOW DENSITY will give the ball mill more work to do. This is reflected in a heavier density being fed back into the hydrocyclone feed pump box. Which again changes the hydrocyclone operation performance.
7. There are two strategy based on the change of feed rate or added water to classifier. Slide 7 effective factors for circulating load First strategy : size of product is controlled by rate of feed and Circulating load by the rate of added water. [8] Second strategy : size of product is controlled by the rate of added water would be controlled.
Similar results have been seen consistently across all the surveys where this approach has been used, including circuits with AG mills, pebble mills, HPGR, stirred mills and ball mills with fine screens. Figure 2 Comparison of the OWi and SSE75 of the SAG and ball mill for 10 surveys conducted on the same circuit at different times.
It goes along with feed. Finally feed to ball mill should be same. But it never happens. After 1st day of operation it gets reduced due to this problems. Fresh feed is reduced. Pumps: If not operated efficiently cyclone will have surging effect and more RCL. While designing a ball mill are all these operating parameters are taken care?
Hydrocyclone Working Principle. Hydrocyclone is a grading device that uses centrifugal force to accelerate ore particle deposition. It needs the pressure to feed ore, so it consumes a lot of power but occupies a small area, cheap, the processing capacity is large, The classification efficiency is high, obtain very fine overflow product, mostly ...
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
Cyclone Feed Pump. A 5″ x 4″ SRLC Pump delivers a minus 1/8″ screen undersize and rod mill discharge at a rate of 288 of 20% solids pulp (270 T/24hr.) to a cyclone requiring inlet pressures to 44 with a vertical lift of 54 feet. The total dynamic head pumped varies from 100 to 150 feet, with 110 feet being the normal operation.
The Ball Mill Discharge Trommel Screen has wide application in practically every type of placer work, in gravel plants, and in oredressing. This type of screen is particularly adapted for screening at coarse sizes, or at finer sizes if spray water can be used freely without interfering with screening. The Trommel Screen consists of a shaft ...

Hydrocyclone size selection for mill concentrator applications: there is more than one good choice ... applications would allow for a few installed spare cyclones, therefore a 10place cluster of the 500 mm cyclones, as shown below, would be a potential selection. ... Through the reduction in pressure and the use of specific sets of cyclone ...
cyclone is a device that uses centrifugal forces to classify solid particles, in a liquid stream, by size and/or density. What does a Cyclone do? If a cyclone is fed with a sand and water mixture containing a range of particle sizes, most of the fine sand will report to the overflow (the top of the cyclone), together with most of the water.
We are looking at a 1 MTPA comminution circuit that goes from a tertiary crush to a single ball mill (closed on a cyclone cluster) to produce a 100 µm P80 product. ... Some are optimized for aggregate and tend to make a coarse product with a minimum of fines and some are optimized for mining and make a finer product with lots of included fines ...
Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semiautogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushinggrinding circuit with three stages of crushing followed by ball mills or ...
Mill throughput is sensitive to changes in the ore type and a collaborative effort, between mining and process personnel, is required in order to maintain acceptable processing rates.
The ball mills are operated at a ball charge volume of 3032% and % critical speed. The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed ...
The simplified flowsheet of the copper ore grinding circuit on which the water added points and sampling locations are seen is depicted in Fig. 1. Within the circuit, two ball mills and two cyclone clusters are in the operation and only the secondary ball mill is closed circuited. The dimensions of the mills and the cyclones are summarized in ...
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.

INNOVATIVE CKT: RGBM cyclone was converted as de watering unit. Under flow was fed to Zinc Rougher cells, (In old it was fed back to Ball mill), Over flow having ultrafines with more water was fed to SCAVENGER cells. This gave surprising results 50% Zn, improved to 53% and Tailing loss from to % Zn. Anyone can try this and find advantages.

An example which clearly underpins this capability is a classification cyclone cluster Multotec recently installed in a milling circuit. The grind of the mill circuit was much coarser than what was originally anticipated, and this resulted in extreme circulating loads that limited the throughput capacity of this process.
The ECS/Process Expert further optimises the balance of the grinding circuit to consider critical parameters such as mill sump level and dilution water addition and cyclone operating pressure. A ...
The velix ® is most commonly placed downstream of either a tra ditional horizontal ball mill or, more recently, polycom ® highpres sure grinding rolls (HPGRs). The product exiting these mills is first fed into a slurry tank 1. The fresh material is pumped to a hydro cyclone cluster 2 to separate the coarse and fine particles.

Hydrocyclones first appeared in dutch in the late 1800s, Hidrociclon is an equipment that uses rotary current to classify, separate or sort coarse particles of sewage. It widely used in mine processing such as aggregates, hard rock mining, sand, industrial minerals, coal and more. Because the equipment without moving parts, take up small areas, process high volumes and relatively cheap.
Hydrocyclones are used in industries such as mining, minerals processing and aggregates to classify, densify, dewater, deslime and recover fines. What is a hydrocyclone in mining? The mining industry makes use of hydrocyclones to separate coarse and fine particles, according to the size and density of the particles.
