Industrial gas specialist, Messer, will showcase its cryogenic grinding solutions at the Powtech 2016 exhibition in Nuremberg, Germany, next week.
Its cryogenic processes use cryogenic gases, such as nitrogen (N2) and carbon dioxide (CO2) to grind composite materials, plastics and foodstuffs, allowing them to be recycled.
Its process is aimed at thermoplastics, elastomers, waxes and paint additives, but it can also cleanly grind spices allowing them to keep their aroma and flavour due to the high temperatures involved.
The materials are cooled with liquid N2 and CO2 making them brittle, so they result in a fine grain when ground. Messer produces sample batches at its cryogenic grinding and recycling technical centre, along with determining grinding parameters and estimating production costs.
Messer, which is the world’s largest privately managed industrial gas manufacturer, is an international supplier of cryogenic gas applications for powder production, and operates its own cryogenic grinding and recycling technical centre near Krefeld, Germany.
Running from the 19th-21st April, Powtech is the international trade fair for experts of powder and bulk solids technology.
Messer invented specialist technology in RWE’s AmpaCity pilot project, for more efficient electricity transmission, which won a German Climate and Environment Innovation Award (IKU) 2015, last night.
