A revised approach to modelling turbulent flow in small-diameter (10–44 mm) hydrocyclones is presented and tested quantitatively against experimental measurements.
The production process features the separation of kaolin from quartz and feldspar by dry and wet processing. The plant equipment consists mainly of: Mining equipment, crusher, roller with classifier, attritioning cells, hydrocyclones, thickener, bleaching equipment, filter press, dryer-pulverizer, bagging.
In kaolin processing, hydrocyclones are the favored devices for the selective separation of fine particles (kaolin) and coarse particles (sand). The advantages of the hydrocyclone include its simplicity, ease of operation, and high volumetric throughput as well as relatively low capital investment, operating and maintenance costs. ...

The particle size of kaolin ore after roughing is generally less than 53 um, which can meet the slurry feeding requirements of small diameter hydrocyclones. Small diameter hydrocyclones have outstanding advantages such as small separation particle size, simple process, low processing cost, and easy operation.
A considerable advantage in classifying kaolins in hydrocyclones (compared with different types of mechanical classifiers) is the possibility of obtaining more finely dispersed products without …
The main drawback of hydrocyclones lies in their lack of versatility, as they are designed for specific operating conditions used in certain industrial process. Thus, the performance of hydrocyclones drastically changes when the features of the upstream (solid concentration, flow rate or pressure) fluctuate.
The kaolin losses in hydrocyclone classification are determined by the fines, which are discharged together with the water to the underflow. This paper presents an improved technique of water injection to the conical part of the cyclone applied especially for small cyclones in kaolin preparation. In small hydrocyclones water, injection is a sensitive process.
