New type pre-dampening nozzle assy for gunning machine
Different from common concrete nozzle assy, for spraying refractory and castable, new type pre-dampening nozzle assy is designed. There are two pieces water supply line in the nozzle assy, front one provide 70% water mixed materials, end one provide 30% water mixed materials. Needle valve precisely controls the amount of water added, greatly reduces dependence on operator skills.

Double ball nozzle tip is made of high wear-resistant rubber, On the one hand, it can reduce the wear of the nozzle tip on the material and increase its service life. On the other hand, can also reduce the rebound of the material during the spraying process.
Two pieces of water rings are equipped with nozzle assy, there are ten pieces small hole in the water ring, atomization occurs when high-pressure water passes through the small holes in the water ring. water mist can quickly be mixed with materials, reduced dust during spraying and increased spraying strength.
As Chinese only one refractory gunning machine supplier, we have exported gunning machine to many countries, like Thailand, Malaysia, Vietnam, India, Indonesia, Estonia, United Kingdom, Kuwait, etc. And receive better feedback from customers.
