grinding mill girth gear

Girth GearsMore than Just Metal and Teeth

Girth gears fall into two basic categories flange mounted and tangential spring mounted. Flange-mounted girth gears the more common of the two are most frequently utilized in "cold" processing equipment such as SAG (semi autogenous grinding) mills and ball mills for use in the mining and cement industries.
