Classification of fine coal with a hydrocyclone - ScienceDirect

The classification performance of a 225-mm hydrocyclone has been investigated. Coal slimes of a nominal 0.5 mm size consist were classified in the separation-range of 0.070 mm to 0.250 mm at solids contents from 6 to 35% by mass, and flow rates of 200 to 700 1 min−1. The partition curves obtained were analysed in...

Cleaning of fine coals by dense-medium hydrocyclone - ScienceDirect

The efficiency of separation for fine coal in a 150 mm dia. dense-medium hydrocyclone has been determined. The partition curves have been measured for particles in the size ranges −500 μm +425 μm, −300 μm +250 μm, −150 μm +125 μm and −90 μm +75 μm. The cut point for separation increases with a decrease in...

Small Diameter Cyclones for DesXinhai - ACARP Abstract

Jul 11, 2011 ... In the Hunter Valley (HV), coal preparation plants often discard ultrafines < 125 micron because of the high clay and high ash content. Recovery of the coal that is currently lost in this fraction can potentially increase plant yield by 1 to 2 %. The use of small diameter hydrocyclones (100 mm) operating at a...
