Author:Moodie, B; Kunstmann, FHDate:1963The results of the petrographic analysis and of the laboratory coking tests are discussed in this report.Read more
Author:Moodie, B; La Grange, CCDate:1958By applying the Burstlein principle of controlled crushing and screening to coal from Blesbok Collier it is possible to obtain a product of lower ash and higher swelling number but it is probably preferable to effect these improvements in the ...Read more
Author:La Grange, CC; Beukes, PJADate:1963Formerly metallurgical coke testing in South Africa was virtually limited to the B.S shatter and abrasion tests. Due to the similarity of the two ASTM tests to the British tests there was no point of introducing the ASTM tests and they will ...Read more
Author:Sorgedrager, PGDate:1961A number of trials were carried out on the Institute's boiler installation with the object to· investigate the possibilities of using washed-charred coal from South Witbank Colliery as fuel. The charred coal was obtained from African Explosives ...Read more
Author:Kunstmann, FH; Kerkovius, HDTDate:1966This report deals with the properties in coal. South Africa has extensive coal deposits but only a small percentage of this coal is suitable for coke production.Read more
