Abstract:
A system includes a distribution tool, a backing, a first plurality of abrasive particles and a second plurality of abrasive articles. The distribution tool includes a first section and a second section. The first section is configured to receive the first plurality of abrasive particles and pass the first plurality of abrasive particles through one or more of the plurality of slots to the backing. The second plurality of abrasive particles differ in at least one of a size, an average weight and a shape from the first plurality of abrasive particles. The second section is configured to receive the second plurality of abrasive particles and pass the second plurality of abrasive particles through one or more of the plurality of slots to the backing.
