Regression Analysis and Neural Network Fitting of Rock Mass Classification Systems
(2018)
Commonly used rock mass classification systems, Rock Mass Rating (RMR), Q-System, and Geological Strength Index (GSI) were used as input for simple regression and Neural-Network fitting. The relationship between the ...
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

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 ...
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, ...
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 ...
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 ...
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 ...
Effect of High Pressure Grinding Rolls (HPGR) pre-grinding and ball mill intermediate diaphragm grate design on grinding capacity of an industrial scale two-compartment cement ball mill classification circuit
(Pergamon-Elsevier Science Ltd, 2016)
Effect of High Pressure Grinding Rolls (HPGR) pre-grinding and two-compartment ball mill intermediate diaphragm grate design on grinding capacity of an industrial scale conventional two-compartment ball mill cement grinding ...
Advances on the fragmentation-energy fan concept and the swebrec function in modeling drop weight testing
(MDPI, 2021)
The breakage index equation (BIE), or t10 model from drop weight testing (DWT) data for rocks and ores is used in the design of crushers and mills. Such models are becoming increasingly difficult to visualize as the number ...
