medium axial hydrocyclone

 

TamScreen TSM GLV

The standard inlet is axial on the top of the screen, with the accept chamber below, and the reject chamber below that. A conventional tangential entry is available as an option, as is a horizontal configuration for large screens. The axial entry provides perfectly uniform distribution of the inlet stock into the screening zone.

HYDROCYCLONES Thermopedia

The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation.

Hydrocyclone Fluid Flow Modelling

Hydrocyclones are widely used in the mineral processing industry as classifying or dewatering units. In general, grinding circuits use a cluster of 5 to 15 hydrocyclones of diameter 50 to 75cm. The slurry from the grinding mill is diluted below 65 solids by weight before it is pumped to the hydrocyclones. The hydrocyclone yields an underflow stream of approximately 70 75 solids by weight and
