The stamp battery is the heart of a stamp mill and the mechanical separation process to break the various components of the ore apart, freeing the gold from its enclosing material. To start, the mined rock enters the mill and passes over a grizzly (like a grate- kit# M1 ) that has bars spaced to allow rocks that the stamp battery can handle to drop through.
