Metal Rascal Ring
The metal Rasching ring was developed by F. Rasching in 1914. It is the earliest invented loose packing material with a fixed geometric shape. Its appearance is simple, and its height is equal to its diameter. Large sized Raschig rings (over 100MM) are generally filled in a neat manner, while Raschig rings smaller than 75mm are generally filled in a disorderly manner. Metal Raschig rings are widely used in many fields, but their main application is as catalyst supports.
