The effect of ball type in fine particles grinding on kinetic breakage parameters
(Polish Mineral Engineering Society, 2015)
In the study, the effect of different grinding media on breakage parameters was investigated. Ceramic and steel balls were used as the grinding media. It was observed that the grinding of ignimbrite obeyed first-order ...
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 ...
Investigation of the breakage parameters of gypsum as dependent on interstitial filling in a laboratory ball mill
(Springer Nature, 2011)
Gypsum is an industrial material used in many applications such as building and chemical industry, fertilizer manufacture, medicine and dentistry. In these industries, there is need for finely ground gypsum. Energy consumption ...
Investigation of breakage behavior of different mineralogical and morphological characteristic pumices
(2011)
The objective of this study is to analyze dry grinding behavior of four different pumices in terms of Bond grindability value, selection and breakage parameters values. For this purpose, firstly, Bond grindability test ...
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, ...
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 ...
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 ...
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 ...
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 ...
