Performance evaluation of a conventional closed circuit process at different cement productions
(TMMOB Maden Muhendisleri Odasi, 2017)
Performance of a conventional Polysius® two-compartment ball mill and a OSepa® high efficiency dynamic air classifier (FLSmidth) closed circuit process was investigated at the steady state conditions at CEM II type Portland ...
Analysis of the self-similarity of single particle impact breakage distributions of cement clinker particles
(TMMOB Maden Muhendisleri Odasi, 2017)
This study analysis how the impact breakage pattern changes at different specific comminution energy levels. Impact breakage patterns of two different cement clinker samples were investigated by plotting size-normalized ...
A rational comparison of groove deepening to relief cutting in terms of tool spacing with drag tools
(TMMOB Maden Muhendisleri Odasi, 2017)
This paper mentions a rational comparison between relief cutting and groove deepening for tool lacing design of partial-face cutting machines employed for mechanical excavations of rocks, coal and stones. The comparison ...
Statistical evaluation of olivine flotation in the presence of dextrin
(TMMOB Maden Muhendisleri Odasi, 2017)
Olivine (Mg,Fe)2SiO4) is an important industrial raw material especially for metallurgical processes such as foundry sand, slag conditioning, production of refractories and iron ore pellets. Olivine alters throughout the ...
Variation of sediment thickness in electrocoagulation as a function of pH, current and temperature
(TMMOB Maden Muhendisleri Odasi, 2017)
In this electrocoagulation study, the effect of three different parameters on the final sediment thickness was tested. For the analysis of the electrocoagulation parameters, the response surface methodology via Box-Behnken ...
Coagulation/flocculation process of marble wastewater: A preliminary (quadratic) statistical model
(TMMOB Maden Muhendisleri Odasi, 2017)
In the scope of this preliminary work, the turbidity removal of an aqueous marble waste was investigated. The effect of the Fe-coagulation and PEO-flocculation on the supernatant turbidity was statistically modelled. The ...
The integrity loss of physicomechanical properties of building stones when subjected to recurrent cycles of freeze-thaw (F-T) process
(Springer, 2006)
In this study, a total of nearly 900 samples were obtained from 7 different rock types, also recognised as marbles of sedimentary and metamorphic origin and commercially used in the building of various monuments, art works ...
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 ...
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 ...
