Application of statistical process control for coal particle size
Deniz, Vedat; Umucu, Yakup (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 effect of ball type in fine particles grinding on kinetic breakage parameters
Umucu, Yakup; Deniz, Vedat (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 effects of ball types on breakage parameters of barite
Umucu, Yakup; Altıniğne, Mehmet Yılmaz; Deniz, Vedat (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 ... -
Estimation of the bond grindability index from the sink-float test data of two different particulate pumices
Deniz, Vedat; Umucu, Yakup; Çayırlı, Serkan (Taylor and Francis, 2012)In this study, equations for estimating the Bond grindability index by the sink-float test data of pumice were developed. Primarily, the cumulative weight and porosity content of the floating fraction were determined for ... -
An evaluation of a modified product size distribution model based on t-family curves for three different crushers
Umucu, Yakup; Deniz, Vedat; Ünal, Nazmi (Oficyna Wydawnicza Politechniki Wroclawskiej, 2013)Crushing is a process which is widely used in mineral processing plants, cement factories, aggregates plants and some other industrial plants. Specific fracture energy of the particles is not the only fundamental property ... -
The evaluation of grinding process using artificial neural network
Umucu, Yakup; Deniz, Vedat; Bozkurt, Volkan; Çağlar, Mehmet Fatih (Elsevier, 2016)Ball milling has been the subject of intensive research for the past few decades. It is indeed the most encountered mineral processing operation of size reduction. Known as the most energy inefficient process, focus has ... -
Flocculation of fine particles in ceramic wastewater by using polymers
Deniz, Vedat; Umucu, Yakup (Polish Mineral Engineering Society, 2014)The clarification of industrial wastewaters by solid-liquid separation techniques and the removal of suspended particles are the problems of growing environmental consciousness. However, there appears to be very limited ... -
Interrelationships between the bond grindability with physicomechanical and chemical properties of coals
Deniz, Vedat; Umucu, Yakup (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 ... -
Investigation of breakage behavior of different mineralogical and morphological characteristic pumices
Deniz, Vedat; Çayırlı, Serkan; Umucu, Yakup (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 ... -
Modeling of grinding process by artificial neural network for calcite mineral
Umucu, Yakup; Çağlar, Mehmet Fatih; Gündüz, Lütfullah; Bozkurt, Volkan; Deniz, Vedat (IEEE, 2011)The grindability properties of calcite sample belong to Afyonkarahisar region were investigated at batch grinding conditions based on a kinetic model. The obtained kinetic model parameters were used to estimate the product ... -
A new model for comminution behavior of different coals in an impact crusher
Umucu, Yakup; Deniz, Vedat; Çayırlı, Serkan (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 ... -
Prediction of the bond grindability index from the sink-float test data of coals
Deniz, Vedat; Umucu, Yakup; Çayırlı, Serkan (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 ... -
The relationship between cement quality and separation cut size
Umucu, Yakup; Deniz, Vedat; Saraç, M. Fahri; Kuzgun, A. Erkan (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 ...
