Decomposition of NO3− by lead pellets with wet ball milling

Waste Management, 1999
Abstract The reduction of an ammonium nitrate solution by lead pellets during wet ball milling was studied, as a method of removing concentrated NO 3 − from wastewater. Metal oxides forming on the surface of lead pellets in a ball mill reactor are continuously removed by contact between the pellets.

Dolomite wet comminution in planetary ball mill

2007
Proces mokrog usitnjavanja često se koristi kako bi se u procesu usitnjavanja spriječilo aglomeriranje materijala. To će rezultirati znatnom uštedom energije i povećanjem učinka procesa. Reološko ponašanje suspenzija dobivenih u procesu mokrog usitnjavanja ovisi o nizu čimbenika: procesnim uvjetima (broj okretaja mlina, broj tijela za usitnjavanje ...

Wet fine grinding in a laboratory stirred ball mill

2010
Fine grinding involves a large number of parameters in its operation. In this study, the effect of some parameters such as initial particle size, filling volume of the ball and ball size distribution on fine grinding of calcite powders (-200, -150 and -100 ?m) using a laboratory stirred ball mill was studied under wet conditions. Zirconia beads (ZrSiO4)

Synthesis of Fe3O4 nanoparticles by wet milling iron powder in a planetary ball mill

China Particuology, 2007
Abstract Fe3O4 nanoparticles with sizes ranging from 30 to 80 nm were synthesized by wet milling iron powders in a planetary ball mill. The phase composition and the morphologies of the as-synthesized products were measured by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).

Wet ball-milling synthesis of high performance sulfur-based composite cathodes: The influences of solvents and ball-milling speed

Electrochimica Acta, 2014
Abstract Wet ball-milling route is employed to prepare sulfur-carbon nanotubes composites. The influences of solvents, including ethanol and chloroform, on the structure and electrochemical performance of the composites are firstly investigated. As compared to the conventional dry-milling process, high loose structure and uniform distribution of ...

An investigation of wet grinding in a laboratory overflow ball mill

Mining, Metallurgy & Exploration, 1989
Batch breakage kinetic tests were performed in a mill of 0.3 m diameter for a range of mill conditions. Accurate simulation required the measurement and use of factors which accelerated the specific rates of breakage of the top sizes as finer material accumulated in the slurry.

A study of the exit classification effect in wet ball milling

Powder Technology, 2004
It is consistently found in wet ball milling, under the conditions normally used in production mills, that the larger sieve size intervals of the product size distributions do not contain as much material as predicted by the first-order mill simulation models. Four methods of correcting for this effect were investigated.

Acceleration of particle breakage rates in wet batch ball milling

Powder Technology, 2002
Abstract Batch wet grinding of 20×30 mesh quartz for slurry concentrations up to 56 vol.% solid showed an increase in the specific breakage rate of the top size feed as fines built up in the mill. The degree of this acceleration effect was represented by a parameter termed the acceleration factor, which depended both on the slurry concentration and ...

Suspension rheology during wet comminution in planetary ball mill

2006
Obtaining and controlling desirable suspension behavior in terms of rheology is important issue in many engineering problems. This research monitors rheological behavior of dolomite suspensions produced by wet comminution in planetary ball mill. Dolomite has a number of uses, in agriculture, steelmaking, glass making, ceramic industry, pharmaceutical ...
