STRUKTUR ZUR STEUERUNG EINES SCHLEIFMITTELSTROMS, SCHLEIFMITTELKLASSIFIZIERER UND STRAHLSYSTEME DAMIT

摘要

The invention provides a structure for control of abrasive flow and a blast system utilizing thereof for blast gun operators to adjust easily and continuously the abrasive flow without any complicated remote-controlled devices. The invention also provides another structure and a blast system utilizing thereof that is capable of forming high-speed and convergent abrasive flow to make full use of the kinetic energy of high-speed compressed air. The invention further provides an abrasive material classifier of high safety and low cost.
