Influence of time-dependency on elastic rock properties under constant load and its effect on tunnel stability
(Techno-Press, 2020)
In structures excavated in rock mass, load progressively increases to a level and remains constant during the construction. Rocks display different elastic properties such as E-i and v under different loading conditions ...
Use of Pinched Sluice in Albite Concentration
(Polish Mineral Eng Soc, 2017)
Albite (NaAlSi3O8) is an important industrial mineral especially for ceramic and glass production. Major Fe-containing impurity of albite ore is flaky mica minerals. This study was conducted to determine the applicability ...
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 ...
Effect of pre-crushing with a vertical shaft im-pactor (VSI) crusher on the performance of an industrial cement ball mill classification circuit
(Bauverlag BV GmbH, 2016)
A vertical shaft impactor (VSI) type crusher can also be used as a pre-crushing unit in cement grinding circuits to carry out an efficient grinding process. This type of application will reduce the total grinding energy ...
Effect of ball load and size distribution on grinding and classification performance
(Bauverlag Bv Gmbh, 2015)
An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag® ball mill on grinding and classification ...
