hydrocyclone has been extensively used for closed circuit grinding and classification system, thickening, des, dewatering, tailings filling, damming, recovery processes in ferrous, nonferrous metal and nonmetal mine industries, and is deeply popular with customers due to high classification efficiency, simple structure, large throughput, and small occupied area.
This is caused when the hydrocyclone is cutting at the wrong particle size (known as the d50 or p80 cut size of the hydrocyclone), or you want to make a coarser or finer cut. The second step in identifying the problem is to identify if this unwanted performance is constant, or if it is intermittent (meaning the hydrocyclone works properly for a ...

Weathered granite contains a high concentration of feldspar, quartz, and kaolin. However, while it becomes rich in clay due to strong physical weathering, the granite minerals that are not fully weathered are still very hard, which makes the grinding process more difficult and limits its use. This study proposes a multi-step process involving grinding, desliming, and …

In kaolin classification, the final product is isolated from the overflow of a 50 mm hydrocyclone with an underflow containing fine sand and residual kaolin. For a higher kaolin recovery, the underflow is usually further treated using a washing cyclone. This paper presents a new development in fine sand washing using water injection in the ...
Finally, the overflow of the third hydrocyclone is the kaolin slurry product, which will be collected in the slurry tanks and sent to the cone thickener for precipitation. The underflow is a higher concentration of kaolin and will be sent to the plate filter press for filtering and getting a relatively dry kaolin cake.
The −125 μm size fraction sample was used to produce kaolin concentrate. Hydrocyclone classification was applied in the pilot study for this purpose. The mass flowrate of the feeds and the products in the hydrocyclones was calculated for the bulk sample as well as the amount of water required operating the process. A kaolin-enriched product ...
The efficacy of desliming the kaolin slurry on reducing the viscosity of the kaolin crude is also investigated and the results are presented. Finally, the mechanism for the improvements in viscosity with the use of these dispersion methods is explained.
The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds of times greater …
The kaolin washing process is generally used for soft kaolin and sandy kaolin. The raw kaolin ore is broken up under the high-pressure impact of water or pulped by tamping. The slurry is pumped into the screw classifier to remove …
