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 ...
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 ...
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 ...
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 ...
Combined effect of pyrometallurgical and hydrometallurgical processes on quartz ore purification
(Chamber of Mining Engineers of Turkey, 2021)
Recent advances in high-tech applications have highlighted the growing demand on highly pure silicates like quartz. Therefore, purification of quartz ore was determined as the subject of this study performed by pyrometallurgical ...
