The effects of ball types on breakage parameters of barite
(Polish Mineral Engineering Society, 2014)Spherical balls are the dominant media shape used in the tumbling mills. However spherical balls wear into nonspherical fragments as a result of breakage due to impact and different wearing mechanisms inside the mill. Thus ... -
The relationship between cement quality and separation cut size
(Polish Mineral Engineering Society, 2015)Cement is prepared by firing a mixture of raw materials, one of which is mainly composed of calcium carbonate and the other of aluminium silicate. The most familiar materials answering to this description are limestone and ... -
Hydrophobicity of galena with ovalbumin and dithiophosphinate in relation to its potential response
(Polish Mineral Engineering Society, 2018)This study was performed to elucidate the role of ovalbumin (OVA) on the hydrophobicity and potential response of galena in the presence of dithiophosphinate (DTPI). OVA was tested as environmentally friendly depressing ... -
Synthesis of Ion-Imprinted Bioadsorbents Based on Chitosan and its Usage in Al(III) Removal
(Springer New York LLC, 2018)As a main goal of the study, a new Al(III) ion-imprinted (Al(III)-IP) bioadsorbent beads were synthesized through crosslinking of chitosan (CS) by epichlorohydrin (ECH) using ion-imprinting strategy and the selective Al(III) ... -
Comparisons of dry grinding kinetics of lignite, bituminous coal, and petroleum coke
(Taylor and Francis, 2013)The objective of this study was to analyze dry grinding kinetics of three different solid fuels in terms of selection and breakage distribution functions values using a batch laboratory ball mill. For this purpose, first, ... -
Interrelationships between the bond grindability with physicomechanical and chemical properties of coals
(Taylor and Francis, 2013)In this research, different techniques for the estimation of Bond grindability (Gbg) values of coals are studied. Data from ten sub-bituminous coals from Turkey are used by featuring physicomechanical (ISI, Is, and FD) and ... -
Prediction of the bond grindability index from the sink-float test data of coals
(Taylor and Francis, 2013)In this study, a relation for calculating the Bond grindability by the sink-float test data of coals was studied. Primarily, sink-float tests for three coal samples were made. Secondly, the cumulative weight and ash content ... -
Application of statistical process control for coal particle size
(Taylor and Francis, 2013)In this article, variations in particle sizes (F50 and P 50) obtained from feeding and ground coals in a vertical roller mill of AS Cement Factory (Turkey) were investigated using control charts and process capability ... -
The use of co-polymer flocculants for the elimination of the environmental effects of wastewater of a coal washer and design of a thickener for supplies of fresh water
(Taylor and Francis, 2013)A washing plant belonging to Özberil Mining Co. (Denizli/Turkey) has a 50 t/h of capacity and coal was washed with heavy media separation to increase its quality. Wastewaters of coal tailing streams of the washing plant ... -
A new model for comminution behavior of different coals in an impact crusher
(Taylor and Francis Inc., 2014)In this study, breakage behavior of three different coals in a laboratory impact crusher was investigated. The laboratory impact crusher carrying three rows of hammers is rotating at 2,840 rpm driven by a 1.1 kW motor. In ... -
A study on the effects of coal feed size and coal type on the performance of a laboratory jaw crusher
(Taylor and Francis, 2014)In this study, the effects at the three different coal size fractions on the five different characteristic coal samples depend on the performance of a crusher in the laboratory. Thus, a jaw crusher was investigated. Based ... -
A new binder in production of water-resistant briquettes from bituminous coals: Co-polymer binder
(Taylor and Francis Inc., 2016)Briquetting could be a solution to economic and environmental problems regarding fine coals. However, briquettes that are formed using molasses disintegrate in water and create problems. Providing water resistance to ... -
