Double inlet blasting gun (double inlet nozzle):
There are two kinds of materials: tungsten steel (made of imported alloy powder of YG3 and YG8) and boron carbide.
It consists of two front and rear nozzles. Due to the effect of high-speed airflow, a large negative pressure is generated. The surrounding air is sucked into the nozzle, so that the amount of air ejected is greater than the amount of air sucked in. This type of nozzle is usually used for large-area medium-strength surface treatment.
The sand blasting area of the double-blast air blasting gun is 35% larger than the standard single-blast blasting area, and the outlet speed of the blasting medium is reduced.
