GZ-1.5ER Mobile portable refractory gunning machine is specifically designed for refractory dry mix shotcrete applications, as well as for concrete shotcrete application. GZ-1.5ER Portable refractory gunning machine is equipped with an ABB frequency inverter and could achieve variable output from 0.7m3/h to 3m3/h.
Compared with the common dry mix shotcrete machine, GZ-1.5ER mobile refractory gunning machine is also provided a new type of pre-dampening nozzle assy, it is equivalent to a pre-wet system, High-pressure water pump provides high-pressure water into nozzle water ring, evenly mix water with refractory materials.
New！！！ Pre-dampening nozzle assy with two water supply ways:
1. Low rebound, low dust;
2. Reduce additive water amount;
3. Improve refractory compactness and strength.
If so, it will reduce the rebound rate. Usually, the common mobile refractory gunning device's rebound rate is about 20%~30%, while the refractory dry mix gunning machine in China's rebound rate is only 10%~15%. As we know, refractory materials price is higher than common concrete, reducing refractory rebound is saving money for customers. Meanwhile, there is low dust in the refractory gunning machine work site, which is helpful for operator to protect their health.
With this GZ-1.5ER small refractory gunning machine, you can get low dust and high performance spraying flow in nozzle.
