High-energy ball milling (HEBM) of powders is a complex process involving mixing, morphology changes, generation and evolution of defects of the crystalline lattice, and formation of new phases. This …
In the wet milling process, the boron powder and tungsten carbide ball were put into the milling jar as in the dry milling process. Also, 15 ml of anhydrous hexane (Sigma-Aldrich, purity of 95%) as a solvent and 1 ml of oleic acid (Sigma-Aldrich, USA) as a coating material were added to the milling jar.After the grinding process, cleaning and …
The choosing of carbon nanotubes as the conductive additives is because that it can offer a three-dimensional conductive net work during ball-milling process to prevent the agglomeration of sulfur. Surprisingly, obvious improvement of electrochemical performance can be obtained just by simple wet ball-milling process. 2. Experimental2.1.
Wet ball mill is a kind of equipment which uses grinding medium and a certain amount of liquid (water or anhydrous ethanol) to grind materials. Unlike dry ball mill, wet ball mill adopts the wet grinding method. The characteristic of wet grinding is that the material needs to be soaked in the liquid for grinding. This method can effectively reduce the …
2.2. Contact modeling. The most critical ingredient in the model of a ball mill is the contact law. Contact models belong either to the (i) discrete or (ii) continuous approach [20].While (i) is based on momentum balances, in (ii) a force–displacement law is added to the equation of motion, as a combination of a spring in parallel with a damper, …
