Application of ANOVA to image analysis results of talc particles produced by different milling
Ulusoy, Ugur (ELSEVIER SCIENCE BV, 2008)This study presents statistical evaluation of the shape parameters for different mill products of talc mineral using Clemex image analysis system. The aim of this study was to determine whether the image parameters of the ... -
Combination of the particle size distributions of some industrial minerals measured by Andreasen pipette and sieving techniques
Ulusoy, Ugur; Yekeler, Meftuni; Bicer, Cevdet; Gulsoy, Zeynep (WILEY-V C H VERLAG GMBH, 2007)It is known that size of the individual particles is the predominant factor affecting the behavior of particulate materials, and that the size effects become increasingly important as the particles become finer. In this ... -
Determination of optimum washing conditions for a lignite coal based on ash and sulfur content
Cebeci, Yakup; Ulusoy, Ugur; Sonmez, Ibrahim (ELSEVIER SCI LTD, 2014)This study deals with the maximization of composite yield subjected to multiple product constraints simultaneously based on float-sink data of a lignite coal from Yozgat-Ayridam district of Turkey by using equal incremental ... -
Dynamic image analysis of calcite particles created by different mills
Ulusoy, Ugur; Yekeler, M. (ELSEVIER SCIENCE BV, 2014)In this study, particle shapes of calcite mineral ground by different mills namely ball, rod and autogenous mills were measured using a new 3D analysis with random orientation technique (by Micromeritics (R) Particle Insight ... -
Dynamic image analysis of differently milled talc particles and comparison by various methods
Ulusoy, Ugur (TAYLOR & FRANCIS INC, 2018)In this study, particle shapes of talc mineral ground by various types of mills were determined using automated dynamic image analyzer by counting averagely 19,000 particles for each mill product. The results were expressed ... -
Dynamic image based shape analysis of hard and lignite coal particles ground by laboratory ball and gyro mills
Ulusoy, Ugur; Igathinathane, C. (ELSEVIER SCIENCE BV, 2014)A new real-time 3D dynamic image analysis system was used to measure the particle shapes of different type of coal samples (lignite and hard coals) ground by different mills (ball and gyro mills). Shape factors such as ... -
Machine vision methods based particle size distribution of ball- and gyro-milled lignite and hard coal
Igathinathane, C.; Ulusoy, Ugur (ELSEVIER SCIENCE BV, 2016)Mechanized coal mining generates a substantial amount of fines that represents significant economic value. Coal fines had several applications, such as gasification, liquefaction, combustion, and beneficiation, but also ... -
Numerical study of granular flow in a slit funnel with a novel structure to avoid particle clogging.
Ulusoy, Ugur; Mühendislik Fakültesi; 0000-0002-2634-7964 (2023)To solve the problem of particle clogging in slit funnels and to obtain a stable discharge flow rate, we proposed a new funnel structure, namely the slit baffle funnel. We conducted a sys- tematic investigation using the ... -
An optimization study of yield for a coal washing plant from Zonguldak region
Cebeci, Yakup; Ulusoy, Ugur (ELSEVIER SCIENCE BV, 2013)In this study, a coal washing plant in Zonguldak was optimized using equalization of incremental product quality approach which maximizes plant yield for a given ash constraint based on float-sink data. By maximization of ... -
Particle size distribution modeling of milled coals by dynamic image analysis and mechanical sieving
Ulusoy, Ugur; Igathinathane, C. (ELSEVIER SCIENCE BV, 2016)Particle size distribution (PSD) of lignite and hard coals ground by ball and Gy-Ro mills were determined and compared using mechanical sieving (MS; direct, width-classification) and dynamic image analysis (DIA; indirect, ... -
Research on the screening mechanisms of composite vibrating screens based on discrete elements
Ulusoy, Ugur; Mühendislik Fakültesi; 0000-0002-2634-7964 (2023)To strengthen the screening efficiency of traditional vibrating screens, a new type of vibrat- ing screen, namely the composite vibrating screen, has been proposed based on the Lissa- jous vibration synthesis theory. The ... -
Zinc Recovery from a Lead-Zinc-Copper Ore by Ultrasonically Assisted Column Flotation
Kursun, Hulya; Ulusoy, Ugur (TAYLOR & FRANCIS INC, 2015)In this study, zinc recovery from lead-zinc-copper ore was performed by column flotation with and without ultrasonic pretreatment. First, optimization of operational parameters was carried out by only single-stage column ... -
ZINC RECOVERY FROM LEAD-ZINC-COPPER COMPLEX ORES BY USING COLUMN FLOTATION
Kursun, Hulya; Ulusoy, Ugur (TAYLOR & FRANCIS INC, 2012)Pb-Zn-Cu complex ore from Balikesir-Ivrindi district have been concentrated by GESOM A. S,. using a selective mechanical flotation technique. Ore feeds containing 3.23% Pb, 0.52% Cu, and 2.71% Zn were concentrated by six ...
