RETSCH laboratory ball mills are available as mixer mills as well as planetary ball mills. Mixer Mills grind and homogenize small sample volumes quickly and efficiently by impact and friction. They are suitable for dry, wet and cryogenic grinding as well as for cell disruption for DNA/RNA recovery.
Dry and wet ball milling approaches are compared on dispersibility of CNT nanofluid. Grinding is effective method for reducing the agglomerated particle size of CNTs. SDS molecule can exert an unzippering force to disperse CNTs in base fluid. Best dispersibility of nanofluid is obtained for purified and wet ground MWCNTs.
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
