The Messer Group is currently presenting itself as an international supplier of cryogenic gas applications for the manufacture of powders, as it exhibits at Powtech 2008 in Germany.

From 30th September to 2nd October, Messer is presenting at the Powtech 2008 event at the Nuremburg Trade Fair Centre and providing information on the separation of composite materials and cold grinding with cryogenic gases, in its own cold grinding and recycling facility.

With the help of cryogenic liquid gases such as nitrogen or carbon dioxide, it is possible to crush materials that have a tendency to melt, are temperature sensitive or have viscous or elastic characteristics.

Cryogen Grinding and separation of composites
With Messer’s so-called cryogenic process, a wide range of different materials can be finely ground or recycled, including thermoplastics, elastomers, waxes and paint additives.

In cold grinding, the substances to be ground are cooled with cryogenic liquid nitrogen or carbon dioxide and made brittle. As a result, particularly small particle sizes can be achieved.

In this way, composites can be economically separated into their pure components in an environmentally friendly manner. Messer supplies all the gases and hardware required from a single source.

In its own technical facility for cold grinding and recycling in Willich, North Rhineland-Westphalia, special sample batches can be produced, permitting an exact estimate of production costs and grinding conditions.
