Planetary Mills are ideally suited for fine grinding of hard, medium-hard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.

The inert gas shielded jet mill is used in metal powder, easily oxidized raw materials, flammable and explosive raw materials, pharmaceutical ultrafine powder and other industries and raw materials that require inert gas protection. Typical materials are: cobalt powder, tungsten powder, iron powder, nickel powder, tantalum powder, selenium powder, …

In inert-gas or free-jet expansion, evaporated atoms are carried by a high-pressure helium gas stream that is expanded from a nozzle into a low-pressure chamber at supersonic velocities. The adiabatic expansion of the gas leads to sudden cooling, causing the evaporated atoms to form clusters a few nanometers in diameter.

TIG welding is an electric, manual welding process that uses a non-consumable tungsten electrode to create a welding arc and an inert argon or helium gas to protect the electrode and weld from oxidation at the high temperatures produced by the welding torch. TIG welding may be performed with or without filler.

A jet mill, or fluid energy mill, grinds material by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size, while continue milling particles above that size, resulting in a narrow size distribution of the resulting product.
