2D Classification of Coal: Refining the Segregation using the 2D Classifier

Get Report
C1603701/10/2007
Author: Kurt Liffman, Ben Aldham, Craig Seath, Ilija Sutalo | CSIRO

The goal of this project was to measure the size and density segregation of -2 mm coal powder that had been processed two times by the CSIRO 2D rotational classifier.

Stage 1: The project commenced in early March 2007, when CSIRO received six 44 gallon drums of coal slurry from ....  read more

 

Dry Classification of Fine Coal

Get Report
C1505504/05/2007
Author: KJ Walton, Kevin Galvin, AM Callen | University of Newcastle

The classification and beneficiation of coal with spirals or cyclones inherently involves high water consumption. The issue of water supply, particularly in arid areas, is further complicated by problems associated with waste tailings generation and disposal. The development of ....  read more

 

Technical and Safety Comparison of DP Cell and Nucleonic Density Gauges

Get Report
C1305020/06/2006
Author: Andrew Vince, Ian Brake, Ben Cronin | BHP Billiton Mitsubishi Alliance

In Australian coal processing practice the measurement of slurry density is of critical to medium importance, depending on the application. A number of means are used for measuring density – traditionally nuclear and differential pressure methods. In recent times nuclear methods ....  read more
