Resumen

ETAYO, JULIO  y  BARRAZA, JUAN. MATHEMATICAL CORRELATIONS TO OBTAIN PRODUCTION YIELD, ASH REMOVAL, AND WATER PARTITION USING A “ONLY WATER” HYDROCYCLONE. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.157, pp.181-193. ISSN 0012-7353.

Mathematical correlations of production yield, ash removal and water partition were obtained to describe the “only water” hydrocyclone (only water as heavy media) behavior from hydraulic and geometrical point of view. A hydrocyclone of 254 mm diameter and a coal from La Yolanda colliery (Valle del Cauca) were used. Mass concentration of coal between 30 and 10% (w/w), vortex finder length between 152.4 and 228.6mm and apex diameter in the range 19.1 to 44.5mm were used. Production yield between 11.9 and 83.2% (w/w) and removal ash between 41.8 and 95.2% (w/w) were obtained. Mathematical equations showed correlation factors up to 98.7%, which predicted good reliability between experimental and theoretical results.
