Chemical injection to prevent building damage induced by ground water drainage from shallow tunnels
(Pergamon-Elsevier Science Ltd, 2009)Progressive developments in the application of chemical injection have been acquired through out the centuries, starting from the ancient Romans. The method of silica based injection has been employed for a long time and ... -
Enhancement of flotation performance of oil shale cleaning by ultrasonic treatment
(Elsevier, 2009)In this study, it was attempted to enhance the performance of flotation cleaning of oil shales by use of ultrasound. The use of an excitation effect through ultrasonication was investigated towards inorganic particles that ... -
INCIDENTAL RELEASE OF BITUMEN DURING OIL SHALE GRINDING AND IMPACTS ON OIL SHALE BENEFICIATION
(Estonian Academy Publishers, 2009)The particle surface characteristics of oil shale and the changes in these characteristics with increasing fineness were determined. FTIR and electro-kinetic studies showed that the surfaces of oil shale particle were ... -
Predicting the relationships between brittleness and mechanical properties (UCS, TS and SH) of rocks
(Academic Journals, 2010)This paper presents the evaluation of uniaxial compressive strength (UCS) predicted from Shore hardness (SH) tests and to correlate brittleness concepts, which are derived from UCS, tensile strength (TS) and Shore hardness ... -
Relations between some quantitative petrographic characteristics and mechanical strength properties of granitic building stones

Studies on increasing the performance of chain saw machines for mechanical excavation of marbles and natural stones
(Pergamon-Elsevier Science Ltd, 2014)Slow cutting rate, tool wear and shallow depth of cuts are important practical issues observed with the commercially available chain saw machines. This paper is concerned with increasing the performance of current chain ... -
Optimization of a fully air-swept dry grinding cement raw meal ball mill closed circuit capacity with the aid of simulation
(Pergamon-Elsevier Science Ltd, 2015)Production capacity of a fully air-swept industrial scale two-compartment KHD Humboldt Wedag (R) cement ball mill was optimized with the aid of simulation. It was proposed to operate the mill as a single compartment by ... -
Effect of ball load and size distribution on grinding and classification performance
(Bauverlag Bv Gmbh, 2015)An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag® ball mill on grinding and classification ... -
Analysis of grinding media effect on specific breakage rate function of particles in a full-scale open circuit three-compartment cement ball mill
(Pergamon-Elsevier Science Ltd, 2015)A full-scale three-compartment FLSmidth (R) cement grinding ball mill with dimensions of empty set3.5 x L10 operating in open circuit was sampled to analyse the grinding media effect on specific breakage rate function of ... -
Optimization of an industrial scale open circuit three-compartment cement grinding ball mill with the aid of simulation
(Elsevier Science Bv, 2016)An industrial scale FLSmidth (R) three-compartment cement grinding ball mill operating in open circuit was sampled at the steady state conditions. The three-compartment ball mill was modelled by using the perfect mixing ... -
Effect of pre-crushing with a vertical shaft im-pactor (VSI) crusher on the performance of an industrial cement ball mill classification circuit
(Bauverlag BV GmbH, 2016)A vertical shaft impactor (VSI) type crusher can also be used as a pre-crushing unit in cement grinding circuits to carry out an efficient grinding process. This type of application will reduce the total grinding energy ... -
Grinding and classification performance evaluation and modelling of an industrial-scale horizontal roller mill process
(Bauverlag Bv Gmbh, 2016)Cement is conventionally produced in multi-compartment type ball mills which is a energy intensive process [3]. Typical energy consumption of the grinding stage of cement production is about 40 kWh/t in a cement plant [4, ... -
