Grit Feeder

The TABER Grit Feeder is a specialized accessory designed to perform abrasion testing using the three-body method. It simulates wear caused by fine, hard particles—like aluminum oxide—commonly found in real-world environments.

Originally developed to test the abrasion resistance of floor coatings, this tool is now widely used across industries that require reliable, consistent evaluation of material durability under abrasive conditions.

How the Grit Feeder Works

The Grit Feeder delivers a uniform and continuous flow of aluminum oxide grit directly onto the specimen surface. As the sample moves beneath two leather-covered wheels, the loose particles roll between the surface and wheels, generating controlled wear.

This action accurately reproduces real use conditions, making it essential for high-quality abrasion testing.
