A pick force calculation method suggested for tool lacing of mechanical excavators employing drag tools
(Taylor & Francis Ltd, 2018)
This paper deals with tool lacing design of partial-face cutting machines employed for mechanical excavations of rocks, coal and stones. A rational comparison between relief cutting and groove deepening was made by simulating ...
Performance Prediction of Circular Diamond Saws by Artificial Neural Networks and Regression Method Based on Surface Hardness Values of Mugla Marbles, Turkey
(Pleiades Publishing Inc, 2019)
Sawing of natural stones with diamond-impregnated circular saws is extensively implemented in stone processing plants in variety of applications that include sawing, cutting, splitting and trimming. Hence, the cost of ...
An investigation on single-particle impact breakage functions of a gold ore by drop-weight technique
(General Directorate of Mineral Research and Exploration (MTA), 2017)
Impact breakage functions for a gold ore from Bergama region (Turkey) was estimated based on the single-particle impact breakage distributions of particles obtained from drop weight tests. For this purpose, a modified ...
Prediction of Top Coal Cavability Character of a Deep Coal Mine by Empirical and Numerical Methods
(Pleiades Publishing Inc, 2018)
Longwall top coal caving mining provides high productivity where thick coal seams exist. The study aims to predict the cavability character of the top coal for deep and thick coal seam in Soma lignite basin located at ...
Rejection of iron coloring impurities of quartz ore by sulfuric acid bleaching
(Baski, 2019)
Quartz purification by bleaching methods has taken great interest for several decades both for conventional and high technology applications like production of optical fibers, construction of silicon cells and semiconductors, ...
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 ...
