A particle-coated substrate (in particular, an abrasive material formed by coating a substrate with abrasive particles) in which a substrate is coated uniformly and in a thin layer with cohesive fine particles, a particle ejector for fabricating the coated substrate, a coated substrate fabricating apparatus comprising the ejector, a particle-coated substrate fabricating method (in particular, a method of fabricating an abrasive material in which a substrate is coated with abrasive particles), and an abrasive sheet. Agitation gas is fed through the porous wall of a particle storage container (110) in the ejector, and an ejection gas is fed from an ejector nozzle (120) through the container to deliver the fluidized particles and ejection gas through a discharge tube (130) generally coaxial with the ejection gas nozzle (120). The particle ejector is capable of attaining a uniform particle size distribution without causing the particles to undergo blocking, agglomeration, or bridging. |
