  • Hydrogenating in a Ball Mill

    May 09, 2018The first time I saw ball-mill chemistry was in the late-1980s. I remember thinking at first that it sounded pretty spaced-out, but it is actually pretty logical. First time I have seen hydrogenation though (and pretty full-on hard-core hydrogenation at that!).

    Feb 03, 2016The biggest problem so far is the noise. It's not just like rumbling of an ordinary ball mill, but imagine two 3-kg cylinders fixed at planetary gears to rotate at 900RPM around the planetary axis rotating about 300RPM powered by 1.2kW electric motor. The noise is so horrible that even when the mill is empty, I must wear protectors in my workshop.

  • Chemistry through ball milling

    Ball milling is one of central techniques of mechanochemical synthesis, that is, chemical synthesis by the action of mechanical force, such as by grinding, stretching, or shearing. Mechanisms underlying chemical reactions in ball milling involve abrasion, shearing, and friction, making ball-milling chemistry one of central areas in tribochemistry.

  • Which is the suitable process for ball milling?

    Wet ball milling is much more effective due to Rehbinder effect producing a disjoining pressure. Adsorption layers from surfactants that arise in microcracks significantly reduce the energy expenditure necessary to crush solid materials as a result of a decrease in their free surface energy upon contact with a medium containing substances capable of adsorption.

  • Ball mill @ Chemistry Dictionary Glossary

    Oct 20, 2018Ball mill is a grinder for reducing hard materials to powder. The grinding is carried out by the pounding and rolling of a charge of steel or ceramic balls carried within the cylinder. The cylinder rotates at a relatively slow speed, allowing the balls to cascade through the mill base, thus grinding or dispersing the materials.
