Process engineering with planetary ball mills
Chemical Society Reviews, 2013Planetary ball mills are well known and used for particle size reduction on laboratory and pilot scales for decades while during the last few years the application of planetary ball mills has extended to mechanochemical approaches. Processes inside planetary ball mills are complex and strongly depend on the processed material and synthesis and, thus ...

Planetary ball milling of MWCNTs reinforced NiAl composites
Materials Today: Proceedings, 2020Abstract Multi-walled carbon nanotubes (MWCNTs) are remarkable reinforcing material with magnificent mechanical features. The presences of sp2 C-C networks in their shells have been responsible for their wide-ranging mechanical abilities. MWCNT are generally known to agglomerate because of the existence of Van der Waals forces, which results in ...

Scale-up method of planetary ball mill
Chemical Engineering Science, 2004The objective of this paper is to investigate the scale-up method of the planetary ball mill by the computational simulation based on Discrete Element Method. Firstly, the dry grinding of a gibbsite powder by using four different scales of planetary mill was developed to compare the grinding rate with the specific impact energy of balls calculated from

Temperature of the milling balls in shaker and planetary mills
Journal of Materials Science, 2006The temperature increase of the milling balls in two laboratory mills, frequently used for mechanical alloying and mechanochemical experiments, was studied using direct calorimetric measurements. The ball temper- ature remains below 100 C in a SPEX 8000 shaker mill and it is cooler when flat-ended rather than round-ended vial is used, although the ...

Synthesis of Nanofertilizers by Planetary Ball Milling
2020Plant nutrients supplied to crops as fertilizers are essential for plant growth, metabolism and production. Inappropriate application of plant nutrients induces 40–70% loss of nutrients and causes contamination of land and water systems. Nano-fertilizers provide nutrients precisely to the plant’s requirement, and thus reduces the environmental loss of ...

High Energy Planetary Ball Milling of SiC Powders
Key Engineering Materials, 2007The effects of high-energy ball milling on SiC powders were studied using a planetary apparatus. Conditions to obtain nanostructured SiC powders with an average crystallite size of 4 nm were determined and powders were characterized by XRD, SEM and TEM analyses. This process was applied to prepare fine powders leading to dense SiC ceramics by sintering

Ball temperatures during mechanical alloying in planetary mills
Journal of Alloys and Compounds, 2002Abstract A simple calorimetric technique was used to estimate the temperature of balls during mechanical alloying (MA) in an AGO-2 planetary ball mill. Temperatures up to 600 °C were realized for balls in the case that compact layers of milled powder are formed on the surface of the balls and the wall of the vial.

Planetary ball-milling: an experimental parameter phase diagram
Materials Science and Engineering: A, 1991Abstract In this paper, we report experimental investigations of the planetary ball-milling process parameters which determine the stationary dynamic end-product structure, i.e. the energy and frequency of the shocks as well as the mean temperature of the vials.
