Understanding the mechanisms of the breakage of ore particles is important to predict the particle size distribution in size reduction operations. This paper aims to show the presence of common breakage modes in impact breakage and ball milling of the cement clinker and chromite samples. For that purpose, narrow size fractions of the two samples were broken in a drop-weight tester or ball mill by changing the degree of applied energy. Then the resultant size distributions were evaluated to seek evidence for the common breakage modes. The results showed that increasing the breakage energy will produce a systematic change in the shapes of the size distributions, suggesting a sequential set of breakage modes. The breakage is initially due to tensile stresses at low breakage energies and compressive stresses at high breakage energies. Further studies should be done to assess if these breakage modes occur at size-reduction of different ores. (C) 2020 Published by Elsevier B.V. on behalf of China University of Mining & Technology.

The effects of feed size distribution on confined-bed comminution of quartz and calcite in piston-die press Hoşten, Çetin; Cimilli, H. (Elsevier BV, 2009-05-16) Packing characteristics of particle beds, determined mainly by the particle size distribution, exert a critical influence on the interparticle breakage of minerals in confined beds under compression. This paper is concerned with the effects of feed size distribution on characteristic phenomena of confined-bed comminution. Minus 3.35-mm quartz and calcite feeds were prepared by proportionately mixing previously classified narrow-size fractions so as to construct particle size distributions having the Gaudin-...
A Mechanistic Model for Predicting Frictional Pressure Losses for Newtonian Fluids in Concentric Annulus SORGUN, MEHMET; Ozbayoglu, M. E. (Informa UK Limited, 2010-01-01) A mathematical model is introduced estimating the frictional pressure losses of Newtonian fluids flowing through a concentric annulus. A computer code is developed for the proposed model. Also, extensive experiments with water have been conducted at Middle East Technical University, Petroleum and Natural Gas Engineering Department Flow Loop and recorded pressure drop within the test section for various flow rates. The performance of the proposed model is compared with computational fluid dynamics (CFD) soft...
The dissolution of ilmenite in HClH2O, HClCH3OH and HClC2H5OH systems — A theoretical approach Türker, Lemi; Goodall, David; Girgin, İsmail (Elsevier BV, 1988-11) Silicon powders are obtained by laser pyrolysis of silane gas. Temperature and velocity profiles are determined both theoretically and experimentally. The velocimetry consists of a marker technique which measures the propagation time of a perturbation front through the hot reaction zone. In the theoretical model, the coaxial jet expansion undergoing a thermal heating is studied by defining a Dorodnitzin-Illingworth transformation. The results show a decrease of axial velocity as the gas enters the laser hea...
The performance of complex-structure fractured reservoirs considering natural and induced matrix block size, shape, and distribution Al-Rbeawi, Salam (Elsevier BV, 2020-09-01) This paper introduces an analytical approach for the performance of the fractured reservoir considering the impact of the matrix block size, shape, and distribution. The objective is better understanding the roles of the variable interporosity flow systems, fracture flowing systems, and reservoir matrix heterogeneity in the responses of the wellbore pressure drop, flow rate, cumulative production, and productivity index. This understanding could help to eliminate the uncertainties and increase the accuracy ...
Determination of SARA fractions of crude oils by NMR technique Kök, Mustafa Verşan; Nurgaliev, Danis K. (Elsevier BV, 2019-08-01) In this research, four different crude oils from Tatarstan oil fields with wide range of API gravities (from 16.6 to 32.5 degrees API) were used for hydrogen and carbon nuclear magnetic resonance spectroscopy (H NMR and C NMR) determinations. The hydrogen and carbon aromaticity factors were calculated by using the results of H NMR and C NMR spectroscopy results. The results show that the aromaticity factors were high for heavy crude oils. For predicting SARA fractions, the correlations were developed as a f...
