The advantages of hydrocyclone desliming. Optional equipment for desliming operations includes hydrocyclones, classifiers, thickeners, etc. After continuous practice in recent years, the use of cyclones for desliming is the most feasible and reasonable. Compared with other desliming equipment, hydrocyclone desliming has the following advantages. 1.
Desliming Hopper, also known as cone classifier, is a simple grading, desilting and concentration equipment, widely applied in gold, silver, copper, iron, tungsten mineral processing. Hydrocyclone, tailings desander, desliming machine, tailings sand desliming equipment, mud washing machine. According to the different particle sizes of the ...
In desliming operation, hydrocyclone is mainly used in gravity separation plant or chemistry factory. In mineral processing plant, desliming hydrocyclone is suitable for dealing with slime under 19μm. 1. The advantages of desliming of hydrocyclone. According to incomplete statistics, the top 50% of the final tailings in the concentrator are ...
Hydrocyclone / Cyclone Cluster. Hydrocyclone is a kind of equipment used for grading the ore pulp by using centrifugal force. Without motion and power unit, it needs to match with relevant slurry pump. It is mainly used in ore dressing industries for grading, separating, concentrating and desliming. Category: Gravity separation equipment.
The primary considerations during the hydrocyclone sizing and selection process is generally given to the different options to achieve operating performance targets. However, the non performance objectives should also be taken into account, for example, in a mill circuit you may need to consider: 1. Capital budget and ease of maintenance:Is the plant looking for the lowest capital cost option involving the minimum number of operating hydrocyclones? 2. Equipment footprint:Is the size of the equipment by the space available in the plant for installation? 3. Operational budget:Is the plant looking at an option to maximise hydrocyclone wear life and minimise energy costs? 4. Day to day flexibility:What is the expected fluctuation in feed conditions? Will any fluctuations be significant enough to require hydrocyclones to be turned on or off to accommodate this change? What will be the impact on hydrocyclone performance from any turn down? 5. Long term flexibility:Is the ore hardn...

Non performance objectives for desliming applications also exist and may include some of those mentioned for mill circuits as well as others that are specific to the application. For example, these could include: 1. Sustainability:Is minimising energy or water consumption a factor? 2. Operational flexibility:Will the size classification change for berm wall building and dam construction? What other non performance objectives may be considered for sand slimes classification around flotation circuits? 3. Mobility:Will the equipment be moved around to different locations? 4. Maintenance:How will the cyclones be handled for maintenance? Are there any weight limitations? Is the installation location accessible by crane?
Global hydrocyclone manufacturers fabricate at least 8 or more different size diameters of hydrocyclones to choose from. The graph below illustrates the offering of a typical hydrocyclone equipment manufacturer for mineral processing applications. In this case, the graph is showing the capacity range for cyclones 100 mm in diameter to 800 mm in diameter. Sizes are available outside this range, but this provides the capacity for the core sizes generally available. The diagram illustrates the wide range of volumetric flows and operating pressures that a single hydrocyclone size can handle. In this graph, the volumetric capacity is shown in cubic meters per hour along the x axis, and the operating pressure , is along the y axis. Note the overlap of volumetric flows that different sized hydrocyclones share. The wide range of flows and operating pressures is made possible because every hydrocyclone size can have a variety of different sized internal fittings such as feed c...
Lets run through an example. The plant wants to size and select hydrocyclones for the following primary mill grinding circuit duty: The first option for selection would be based upon the lowest capital cost and the fewest number of operating hydrocyclones. Based on this selection criteria and the feed conditions, it would be customary to offer seven operating 500 mm diameter cyclones to meet these performance requirements. Typically, applications would allow for a few installed spare cyclones, therefore a 10 place cluster of the 500 mm cyclones, as shown below, would be a potential selection. The second option for selection would be focused upon achieving extended wear life in the liners, lowering energy costs and having the ability to produce finer classifications . Based on this selection criteria it would be common practice to offer, twelve smaller 400 mm diameter hydrocyclones to meet the performance requirements. Through the reduction in press...
Now, lets consider a plant desliming application. In this example the plant wants to size and select hydrocyclones for the following desliming application: There are 5 different options of hydrocyclone sizes to consider. The following table shows the results for hydrocyclones from 500 mm in diameter all the way up to 900 mm in diameter. 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. If the smaller hydrocyclone diameter is used, the total solids recovery of material to the hydrocyclone underflow would be higher. In all 5 options, the equipment will meet the specification provided, however when you consider all of the non performance objectives, the best selection may...
