A Simulation Study of Laboratory Scale Ball and Vertical Stirred Mills

01-Dec-2009 | Samanli, Selcuk; Cuhadaroglu, Dilek; Kizgut, Sait, Particle & Particle Systems Characterization, 2009

Abstract The aim of this study was to investigate the grindability of solid fossil fuels from a thermal power plant by using a vertical stirred mill and conventional ball mill. The solid fossil fuel sample was obtained from the Zonguldak Catalagzi thermal power plant in Turkey. The sample below ...

Developing foundry alloy preparation technique for producing highly porous permeable cellular chromal

06-Nov-2009 | G. V. Bashkirtsev, Russian Journal of Non-Ferrous Metals, 2009

The purpose of the work was to experimentally investigate, simulate, and optimize the crushing methods of foundry alloys. The kinetics of crushing of the Fe-Cr-Al foundry alloy, which was performed in the drum and vibration mills, was investigated. The particle size was determined by two methods, ...

Dextranase in sugar industry: A review

25-Jul-2009 | Efraín Rodríguez Jiménez, Sugar Tech, 2009

In sugar production, dextrans are undesirable compounds synthesized by contaminant microorganisms from sucrose, increasing the viscosity of the flow and reducing industrial recovery, bringing about significant losses. The use of the dextranase enzyme is the most efficient method for hydrolyzing ...

The Role of Particle Morphology in the Mechanochemical Activation of Hematite

03-Nov-2004 | M. Sorescu, D. Tarabasanu-Mihaila, L. Diamandescu, Journal of Materials Synthesis and Processing, 2004

Hematite particles of four morphologies (polyhedral, platelike, needlelike, and disk shape) were synthesized by the hydrothermal method. The morphology and average particle diameter (1.4, 7.4, 0.2, and 0.12 µm, respectively) were determined by transmission electron microscopy (TEM) combined with ...

Preparation of a Fine Powder of a Bi-Based High-Tc Ceramic Superconductor by Wet Ball-Milling: Effect of Fluids on Grinding Performance

03-Nov-2004 | Hidenobu Itoh, Koichiro Nakai, Shinichi Motai, Satoshi Maeda, Journal of Materials Synthesis and Processing, 2004

A Bi-based high-Tc ceramic superconductor (Bi1.6Pb0.4Sr2Ca2Cu3Ox) was milled in various fluids and the effect of fluids on the crystal structure and morphology of the milled powder was studied. It was found that methyl acetate is an excellent fluid for wet grinding without decomposition of the ...
