Explained rotating abrasive jet nozzle jet nozzle wear serious than ordinary phenomenon

Comparison of the rotating abrasive jet nozzle and the general stress abrasive jet nozzle, the results showed that: the former is much larger than the maximum stress in the latter, which could well explain the rotating  Polycrystalline diamond  nozzle jet nozzle wear serious than  abrasive grinding . Study of the various parameters of the law of the nozzle wear, these parameters were as follows: the abrasive characteristics (shape abrasive,  Diamond blade  size, grain hardness, abrasive concentration), nozzle material properties and surface quality (hardness nozzle, abrasive hardness H_α and nozzle material hardness H_m ratio nozzle processing quality), nozzle structural parameters (inlet contraction angle, nozzle diameter), the jet operating parameters.
