Designed to evaluate the resistance of floor surface coatings to abrasion
TheGrit Feeder is used to evaluate three-body abrasion caused by the destructive action of fine, hard particles. Originally designed to evaluate the resistance of floor surface coatings to abrasion, this instrument distributes a consistent flow of aluminum oxide grit onto a specimen surface before it passes under a pair of leather-clad wheels. The grit particles serve as the abradant and aids in the rolling action that contributes to the materials breakdown.
