Chat OnlineAdvantages of Cryo Grinding
Temperature management is one of the main challenges of industrial grinding. During operation the ambient temperature inside conventional mills can rise to over 390°F (200°C). At that temperature many materials deform or melt before they can even be pulverized. Other materials may not degrade but remain too flexible to properly grind.
