7 Grinding Hub is the new trade fair and the new center for grinding technology. Frankfurt am Main – Fine machining requires a great deal of intuition. That is why many companies still take care of grinding and polishing manually. However, this can quickly become a source of high costs and inconsistencies, especially in series production.

Cryogenic Preparation of Polystyrene for Fine Grinding Significantly improved milling KPI. Polystyrene pulverizing: 20% higher flow rate, very narrow particle size distribution and enhanced process stability through cryogenic embrittlement of the material.

At normal temperature, some sensitive or sticky or elastic materials cannot be ground to a fine-grained powder, even when the grinding media are run at high speed. This grinding mill with liquid nitrogen adopts outer media freezing method to pulverize the materials to realize the heat exchange between material and liquid nitrogen, which can ...
