Characteristic

The inner core use imported high purity boron carbide raw materials, produce with high-tech equipment and fine process.Nozzle have long service life, high hardness, high strength, high chemical stability, light weight, high temperature resistance, corrosion resistance and other characteristics,which is 3-4 times service life than tungsten carbide nozzle.

Remark:1.The size can be  customized according to customer's require

            2.The shell can be made of aluminum or steel
            3.Fine thread or coarse thread for choose

Production process

1.Boron carbide and other raw materials grind in ball crusher(72 hours) 

2.die-filling

3.hot press molding(2500°C)

4.natural cooling

5.Mould unloading

6.end preparation

7.Shell processing and surface treatment

8.Assemble

9.Inspection and storage

The different between single venturi and double venturi nozzle

Single venturi nozzle is the long range type, one air inlet. 

Double venturi belongs to high speed type, with eight holes around the shell, due to the high speed air flow, the speed of air ejecting faster than compressed air, speed of blasting is higher.
