Shredder Grates By Qiming Casting®

Shredder grates are the most important shredder wear parts. The grates ensure that shredded metal does not leave the shredding zone (hammermill) until shredded metal pieces are reduced to the desired size. The characteristics of the grate’s openings are determined by shredded-metal specifications and operating parameters. The grates sustain substantial abrasion and impacts from the rapidly moving metal inside the hammermill.
