Tungsten Carbide Porous Nozzle Factors IV

Related experimental statistics showed that with the rising of the nozzle pressure drop, cracking volume increased linearly. At the same pressure drop conditions, the aperture of porous nozzle for rock cracking is similar, mainly affected by the bore distribution and less by the outside aperture. In addition, the pressure drop enlarges the rock volume caused by the bore depth increase, and the increasing pressure drop will improve the effective spraying distance. There is a best spraying distance, which has enough impact energy and can cover almost of area.
