Grinder Machine: How to Choose the Grinding Media

Most metal grinding machines consist of a substrate inside a rotating drum. Rod mills are used to make metal bars, while semi-autogenous grinding (SAG) mills and autogenous grinding machines can polish copper, gold, platinum, and silver. An important part of the grinding process is the selection of the correct grinding media.
