(University of Pretoria, 2012)High and medium-pressure roller crushers operate on the principle of inter-particle crushing by crushing material in a packed bed. Although reference in the study is made to high-pressure roller crushers, the work was done ...
-
(University of Pretoria, 2013)Diamonds are commonly present in an ore called kimberlite. Kimberlites vary extensively in mineralogy and therefore can complicate the processing and the extraction of diamonds. Weathering of kimberlite was investigated ...
-
(University of Pretoria, 2013)The Anglo American Platinum Converter Plant produces a copper-nickel sulphide converter matte which is slow-cooled in ingots over several days. During the process, the formation of alloy platelets, containing the majority ...
-
(University of Pretoria, 2013)The aim of the work presented was to investigate the effects of upper bainite on impact toughness in quench and tempered low alloy plate steels. The experimental research included construction of CCT diagrams by dilatometry, ...
-
(University of Pretoria, 1994-11-20)The interactions between engineering materials and their environment which give rise to stress corrosion cracking are reviewed and industrial examples from the petrochemical industry are described. In one of the examples, ...

(University of Pretoria, 2012)High temperature gas cooled nuclear reactors often make use of Tristructural Isotropic (TRISO) coated fuel particles. In these particles, a layer of silicon carbide plays the key role of providing mechanical strength and ...
-
(University of Pretoria, 2007-01-11)The primary crushing circuit at Premier Diamond Mine was simulated to improve operating costs and diamond recovery. Due to surges in certain feed streams a dynamic simulation was done. The applicability of the general-purpose ...

(University of Pretoria, 2006-12-21)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2006-12-21)The aim of this study was to determine the influence of alumina increase on the functioning of casting powder during continuous casting. Two aspects of the powder's performance were experimentally measured, namely the ...
-
(University of Pretoria, 2007-12-19)The influences of a superheated steam environment and temperature on the nearthreshold crack growth behaviour of mild steel during rotating bending fatigue were investigated. A fatigue machine in which rotating bending is ...
-
(University of Pretoria, 1998)During the past two decades many efforts have been made to increase the control of blast furnace conditions to ensure a homogeneous product. The dissections on blast furnaces by various iron and steel companies in Japan ...

(University of Pretoria, 2007-02-19)Please read the abstract in the 00front part of this document
-
(University of Pretoria, 2013-01-08)Slat-band chains are used as conveyors by the food industry, breweries and bottling plants. The operating conditions require abrasion resistance and strength which are at the limit of the capabilities of the current material ...
-
(University of Pretoria, 2006-12-01)As one of the most abundant elements on earth, iron is nearly always present in metal concentrates. This is specifically true for zinc sulphide concentrates, which can contain up to 18% iron (marmatite). Today more than ...
-
(University of Pretoria, 2012)During the aluminium electrolysis process, pot linings determine the life span of the cell. As a result there has been considerable and ongoing research internationally on the penetrating chemical species and phases that ...
-
(University of Pretoria, 2009-12-09)Effects of mould flux contaminant on scale-steel adhesion and hydraulic descaling of scale formed on slabs were investigated. In this investigation, stainless steel type 304 (austenitic with 18% Cr and 8% Ni) and specific ...
-
(University of Pretoria, 2010-02-05)The effect of austenitising and tempering practice on the microstructure and mechanical properties of two martensitic stainless steels was examined with the aim of supplying heat treatment guidelines to the consumer or ...
