Estimating particle size of hydrocyclone underflow ...

2015-6-30 · underflow of the hydrocyclone. Likewise, multiple linear regression and neural network models were used to estimate the underflow solids content and mean particle size in the hydrocyclone underflow. The LDA model could predict the PGM ore types with 61% reliability, while the NN model could do so with a statistically similar 62% reliability.

Hydrocyclone Underflow Discharge Angle Monitoring

2021-2-8 · Hydrocyclone Underflow Discharge Angle Monitoring and Control Hydrocyclones are crucial classification devices in many mineral processing circuits. Hydrocyclones are designed to operate at specified feed conditions (pressure, flow and density) in order to operate optimally providing good separation with acceptable product density and flow.

Controlled wash water injection to the hydrocyclone

2010-3-1 · 1.. IntroductionThere have been several attempts focused on improving the washing of the sediment in the conical section of the hydrocyclone (Honaker et al., 2001, Udaya et al., 2004, Udaya et al., 2005).Tangential water injection into the cyclone cone has been applied to displace feed pulp water in the underflow stream and increase the sharpness of the separation (Dahlstrom, 1954).
