Abstract
Particle delivery apparatuses for use in abrasive-jet systems and associated apparatuses, systems, and methods are disclosed. A particle delivery apparatus configured in accordance with a particular embodiment includes a cutting head, a gas inlet, and a control junction. An abrasive delivery path extends from a particle hopper toward the cutting head. A gas flow path extends from the gas inlet toward the cutting head. The control junction is configured to collect abrasive particles in a pile that blocks a flow of abrasive particles along the abrasive delivery path. The pile forms when a gas flow rate through a free space around the pile and a pressure differential between the hopper and the abrasive delivery path downstream from the control junction are insufficient to partially or entirely displace the pile.
