Use of Hydrocyclone Filter in Silica Sand Processing

1. Use of Hydrocyclone Filter in Silica Sand Processing A hydrocyclone is a cyclonic separator that separates the product phases utilising the difference in gravity with fluids as the primary feed. It is commonly used in irrigation industries as well as silica sand processing. The working of a hydrocyclone filter is quite simple. The fluid enters a tangential line from the upper structure. Under the effect of a centrifugal force, the heavy particulate matter gets pushed towards the wall and rotates downwards to discharge. In contrast, the smaller matter rotates to a certain extent before it gets discharged from the upper vortex. A hydro cyclone filter is also used for grinding classification, sorting, concentration and dehydration in silica sand processing. Read along to learn how the filter helps in above mentioned procedures. 1.Hydrocyclone Grading and Grinding System A hydrocyclone helps in the classification of coarse sand and overflow of the ball mill, along with the pre-grading of the grinding operation. The process is very similar to that of a mechanical classifier and can easily replace it. This helps in reducing the equipment cost of the process. A hydrocyclone is most useful in cases where the concentration of slurry is large, and the mechanical classifier cannot obtain a fine overflow. However, in such cases, there is a high risk of wear in the filter lining. Therefore, reputable hydrocyclone suppliers use a high-wear resistant material as lining to fix the problem and reduce the maintenance cost. 2. Mud Removal Industries utilise the benefits of hydrocyclone filters for the demineralisation of various metallic or non-metallic minerals. The filter completes the demineralisation in four steps: 1.It improves the selection index for preparation work before the final sorting 2.It removes the floatation agent on the ore particles 3.It removes the coarse sand from non-metallic minerals 4.Presents the final concentrate. 3. Concentration In many processes, the low concentration of the sand slurries makes it crucial to opt for a hydrocyclone filter for a concentration treatment.

2. 4. Impurity Removal The main prerequisite for a beneficiation process includes sand and impurity removal. Even after mashing, some impurities might be present in the slurry. For these impurities, a hydrocyclone is the best cleansing equipment. Sometimes, the different nature of the ore may need a combination of hydrocyclones having different specifications to meet the process requirements. 5. Tailings Filling and Damming Fine sand is not a suitable material for tailings dam construction. Therefore, the sand is classified via a hydrocyclone when using tailings for dam construction. The tailing filling scheme is typically pre-concentrated and classified by a cyclone. It is then dewatered in the filter to achieve the best effect. Wrapping Up: A hydrocyclone filter is not limited to just the operations mentioned above. It is multifunctional helpful equipment not only in the beneficiation industry but also in chemical, paper, construction and other industrial sectors. You can contact a leading process equipment manufacturer in Gujarat to learn more about the hydrocyclones of different specifications and the one most suitable for your industry.
