Design Of Abrasive Jet Machine

Abstract: In abrasive jet machine, abrasive particles with high velocity are impacted on workpiece. Work material is removed by erosion action. High velocity of particles, proper mixing of air and abrasive paticles are important factors for good working of abrasive jet machine. Considering this, we have made design of mixing part of abrasive jet machine. This design uses pressurized abrasive feed. This pressuried abrasive powder is then mixed with high pressure air. Pressure is obtained in both uses from same pressure supply. Abrasive flow is designed to be controlled by pinch of valve. All design calculations and methodology used is given further in paper
