GRATES

GRATES

Description

The bottom grate ensures that shredded metal does not leave the shredding zone until shredded metal pieces are reduced to the desired size. The bottom grate sustains substantial abrasion and impacts from the rapidly moving metal inside the metal shredder. Bottom grates are often replaced at the same time as anvils and breaker bars.
