Investigation of chromite preconcentration by comminution
(Baski, 2019)
Chromite is the main source of chromium. It is widely used in metallurgical, refractory and chemical engineering applications. Chromite occurs in earth crust generally with serpentine minerals as associated gangue. Serpentine ...
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 ...
Effect of operational conditions on energy efficiencies of air-swept ball mill and classification circuits in cement raw material production
(Baski, 2019)
Operational performance and energy efficiencies of cement raw material grinding air-swept ball mill and classification circuits were analysed and discussed in this study. Extensive sampling surveys were performed around ...
Quartz bleaching by oxalic acid: Relationship between rejection rate of impurities and color response
(Baski, 2019)
Quartz beneficiation has been applied to meet market requirements by physical and/or chemical methods. Chemical beneficiation has long been investigated by inorganic (e.g. sulfuric acid) and organic (e.g. oxalic acid) ...
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 ...

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, ...
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 ...
Assessing Rock Mass Permeability Using Discontinuity Properties
(Elsevier Science Bv, 2017)
Field measurement of rock mass permeability is essential that numerous factors influence its directional magnitude. Lugeon test is a popularly conducted field instrument in order to measure hydraulic conductivity of a rock ...
