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 ...
ASIRI BASKILI SINIFTA BIR KAYA KÜTLESINDE AÇILAN DERIN YERALTI AÇIKLIKLARINDA TAHKIMAT SISTEMLERININ DAVRANISI
(Baski, 2019)
Large-scale and persistent deformations can be observed when the ratio of the stresses around the underground opening to the strength of the rock mass is unfavourably disturbed. Such ground behaviour is called squeezing ...
SOMA KÖMÜR HAVZASINDA BIR YERALTI İŞLETMESİNDE ALT TABAN YOLU DESTEK SİSTEMİNİN İYİLEŞTİRİLMESİ
(Baski, 2019)
Maingate and tailgate entries bearing paramount importance for the underground coal mines where the longwall method is employed, cause many down-times when they are exposed to excessive deformation. In order to reduce the ...
SEDİMANTER ZAYIF KAYA KÜTLESINDE REÇİNELİ HALAT SAPLAMALARIN UYGULAMA PARAMETRELERİNİN ÇEKME DAYANIMINA ETKİSİ
(Baski, 2019)
Cable bolts which are efficiently used in mining operations, have become widespread in local underground coal mines. Presentation of information about the cable bolt performance in sedimentary units encountered in local ...
