Abrasion Testing Instruments

Grit Feeder Attachment

grit_feeder_attachment.jpgThe Grit Feeder Attachment is used with the Taber Abraser (Abrader) to evaluate three-body abrasion caused by the destructive action of fine, hard particles.  Originally known as the Frick-Taber test, this instrument has been used to determine the wear resistance of floor coverings with smooth and embossed surfaces.

The Grit Feeder is a freestanding instrument which is positioned over the Taber Abraser specimen holder.  Abrasive grit particles are deposited uniformly and continuously onto the specimen surface.  As the specimen holder rotates, the loose grit particles pass under a pair of leather-clad wheels.  The resulting rolling action of the particles serves as the abrasive and contributes to the physical breakdown of the material.  The vacuum hose from the Taber Abraser is inserted into the base of the Grit Feeder and a vacuum pickup tube is positioned over the specimen so grit particles and debris are removed.  The operation of the grit feeder is controlled through the Taber Abraser, ensuring that the turntable, grit distribution and vacuum suction are actuated at the same time.

IMPORTANT: Due to the type & quantity of abrasive media that is used during this testing, Taber recommends that you frequently inspect the vacuum filter and collection bag and replace when necessary.
