Particle separation efficiency in two 10-mm hydrocyclones
2009-5-1 The hydrocyclone particle separation efficiency is affected mainly by the centrifugal effect generated by the rotational liquid flow. The centrifugal effect is determined by the hydrocyclone geometry, inlet flow rate and underflow to overflow split ratio. The complex hydrodynamic phenomena occurring within a hydrocyclone require great attention

2012-12-1 Highlights Hydrocyclone efficiency was improved by installing conical top-plate. The conical top-plate reduced the low velocity regions near the vortex finder. Installing a conical top-plate led to quicker particle collection. The simulated particle separation efficiency agreed well with experimental data. The optimum cone angle of top-plate was 30°.

Experimental study of particle separation and the fishhook
2014-5-24 An effective separation by a mini-hydrocyclone should result in a step function where coarse particles are separated to the underflow with a high efficiency followed by a sharp transition at the d50value with minimal fines exiting through the underflow. This is not achieved in practice, but a typical separation efficiency curve should decrease monotonically with decreasing particle size. Zhu et al. (2012)also found that as the inlet velocity was increased, the d50value decreased with a corresponding steeper separation

Design of novel hydrocyclone for improving fine particle
2013-1-14 Hydrocyclone is a unit operation used for separating particles or droplets from liquid dispersion media. Because the feed suspension flows into a hydrocyclone rotationally, large particles are collected into the underflow due to the centrifugal effect generated by fluid rotational flow. Small particles migrate into the secondary flow near the central part of the hydrocyclone and flow out through the
