What are the technical requirements for silicon carbide nozzles

Some users in the hardware industry are relatively familiar with the characteristics of silicon carbide nozzles and know that the grinding efficiency of boron carbide is very high, so they generally use it as a grinding medium in the material grinding process, especially for grinding, grinding, drilling and polishing of hard materials such as gemstones, ceramics, tools, bearings, hard alloys, etc.
Requirements for nozzle arrangement
The spacing of nozzle layout shall be reasonable. The conical water mist sprayed from the nozzle shall overlap each other without leaving a gap, or the smoke may slip away from the gap without contacting the droplets. Adjust the density of nozzle layout and the number of spray layers to obtain different spray overlapping degrees. The higher the overlap, the higher the desulfurization efficiency, but the resistance will also increase. Generally, the overlapping degree of spray is 200% - 300%, and another requirement of nozzle layout is not to wash tower wall, spray header and support
Angle of nozzle
The spray angle refers to the cone angle of the liquid film cone formed after the slurry leaves the nozzle mouth, which is mainly affected by the radius of the nozzle hole, the radius of the rotating chamber, the radius of the slurry inlet and other factors. When selecting the spray angle, it must be combined with the nozzle layout in the tower to ensure the coverage uniformity and coverage rate in the tower. Generally, the spray angle is required to be 90~120.
Pressure of nozzle
The pressure drop of a nozzle refers to the pressure loss caused by the slurry passing through the nozzle channel, mainly related to factors such as nozzle structural parameters and slurry viscosity. The greater the pressure drop, the greater the system energy consumption. The typical pressure drop of nozzles in general spray systems is between 0.05 and 0.15 MPa.
Flow rate of nozzle
The nozzle flow rate refers to the volume flow rate passing through the nozzle per unit time, which is related to factors such as nozzle pressure drop and nozzle structural parameters. Under the same nozzle pressure drop conditions, the larger the nozzle hole radius, the greater the nozzle flow rate.
