PROBLEM TO BE SOLVED: To easily pulverize a material difficult to be pulverized by a general method, like tough and highly elastic plastics, plastics of low melting point, or a metal with high expansibility, with a pulverizer using mainly ordinary impact, into particulate of about 10μm. SOLUTION: In this pulverizing method, plastics and metals are formed into thin films and closely adhered to each other to form a multi-layered film, and the film is fed to a puverizer.
