Abstract
A method of shape sorting abrasive particles involves disposing initial crushed abrasive particles with agitation against the surface of a tool, the surface defining a plurality of shaped cavities having an average aspect ratio of at least 1.2, thereby causing a first portion of the initial crushed abrasive particles to become retained within at least some of the shaped cavities, and causing a second portion of the initial crushed abrasive particles to remain as loose particles on the surface. Substantially all of the shaped cavities contain at most one abrasive particle. The second portion of the initial crushed abrasive particles is separated from the tool. The first portion of the initial crushed abrasive particles is then separated from the tool and isolated as loose sorted crushed abrasive particles. The average aspect ratio of the loose sorted crushed abrasive particles is greater than that of the initial crushed abrasive particles.
