Effect of increase in feed inlet pressure on feed rate of dense media cyclone

Research on the intelligent control of the dense medium separation process in coal preparation plant

“…The references indicate that the recent studies about the dense medium separation almost center on the flow characteristics in the separators (Narasimha et al, 2007;Wang et al, 2009;Chu et al, 2009;Sripriya et al, 2006;Mukherjee et al, 2003;Mohloana, 2008;Magwai and Bosman, 2007;Peng and Xia, 2007) and the fuzzy control tracking the desired density home and abroad (Celik, 2009;Firth, 2009;Barbee et al, 2008;Spencer and Liu, 2005;Accession number: 20070610411506, 2007;Luttrell et al, 2010;Liu and Wang, 2007;Liu, 2008;Zhao, 2007;Yang and Wang, 2005;Yu and Shi, 2006;Li et al, 2009). There are few studies on solving the problems mentioned above.…”

Performance characteristics of pilot plant dense media hydrocyclone for beneficiation of coal and 3-D CFD simulation

“…Sripriya et al (2006) examined the various variables affecting the efficiency of the dense medium cyclones to identify those that affect the DMC operation and identified the new levels of parameters to bridge the gap between the actual and the ideal. Mukherjee et al (2003) studied the possibility of increasing feed rate to DM cyclone by increasing the feed inlet pressure and the effect of increased feed inlet pressure on media behavior of the DM cyclone. Honaker et al (2007) evaluated the ability of the Knelson concentrator to achieve ultrafine particle size separations by installing a pilot-scale, continuous discharge model in an eastern US coal preparation plant.…”

Numerical investigation of the separation behaviours of fine particles in large dense medium cyclones

“…Increasing operational Head may improve the performance of different cyclone separators according to the experimental observations reported by different investigators (Fassani and Goldstein, 2000; (a) (b) Mukherjee et al, 2003;Witbeck and Woods, 1984). Its effect on the behaviours of fine particles is thus specifically examined and quantified for the 2-m DMC.…”
