The particle delivery system includes a particle belt having a particle engagement section configured to receive the particle via the particle engagement aperture and a particle exit section configured to expel the particle via the particle exit aperture. The particle exit section is positioned adjacent to the particle exit aperture, the particle belt extends generally parallel to the trench at the particle exit section, the particle engagement section is positioned adjacent to the particle engagement aperture, and the particle belt at the particle engagement section extends at an angle between zero degrees and ninety degrees relative to the particle belt at the particle exit section.
