Ceramic sandblast nozzles are used in abrasive blasting, sandblasting, surface treatment, shot blasting, rust removal, coating preparation and industrial cleaning equipment. In these working conditions, high-speed abrasive particles can wear metal nozzles quickly, leading to bore enlargement, unstable blasting pressure and inconsistent surface treatment results.
CERAMPRO manufactures custom ceramic sandblast nozzles using alumina ceramic, silicon carbide ceramic, boron carbide ceramic and zirconia ceramic. Based on the abrasive media, working pressure, expected service life and cost requirements, we help customers select a suitable ceramic material and nozzle design for their application..

Application Case: Ceramic Nozzles for Sandblasting Equipment
A surface treatment equipment customer was using metal nozzles in a continuous abrasive blasting process. During operation, the nozzle inner bore wore quickly, which caused unstable blasting pressure and inconsistent surface treatment results.
After reviewing the abrasive media, nozzle size, working pressure and expected operating time, CERAMPRO recommended testing silicon carbide ceramic nozzles as an alternative solution. Silicon carbide ceramic was selected because of its high wear resistance, good corrosion resistance and stable performance under abrasive flow.
Compared with the original metal nozzles, the ceramic nozzle solution helped improve bore stability, reduce replacement frequency and support more consistent blasting performance during continuous operation.
This case shows that the best ceramic nozzle material should be selected according to abrasive media, working pressure, service life requirements and cost targets
- Longer service life
- Reduced replacement frequency
- Improved bore stability
- More consistent blasting performance
