Shredder Grates Supplier

When it comes to shredder grates, Qiming Machinery is a specialist supplier. Qiming Machinery enjoys a history of custom designing shredder grates.Our bottom grates provide optimal balance of strength, performance and weight efficiency. The wider profile translates into higher mechanical strength. As a result, you can push the geometry and create a greater open area for increased throughput.

The bottom grate ensures that shredded metal does not leave the shredding zone (hammermill) until shredded metal pieces are reduced to the desired size. The characteristics of the bottom grate’s openings are determined by shredded-metal specifications and operating parameters. The bottom grate sustains substantial abrasion and impacts from the rapidly moving metal inside the hammermill.
