Best quality refractory gunite concrete spray equipment for tunnel

Best quality refractory gunite concrete spray equipment for tunnel is designed for spraying refractory materials that can be poured in steel mills. Unlike normal dry mix shotcrete machines, there are ABB frequency converters, new pre-attenuated nozzle assemblies, and high-pressure water pumps for refractory gunite concrete spray equipment. ABB drives are used to adjust the output from 1m3/h to 3m3/h. If the output volume increases when spraying starts, the material can block the delivery of the delivery hose

Best quality refractory gunite concrete spray equipment for tunnel is designed for spraying refractory materials that can be poured in steel mills. Unlike normal dry mix shotcrete machines, there are ABB frequency converters, new pre-attenuated nozzle assemblies, and high-pressure water pumps for refractory gunite concrete spray equipment. ABB drives are used to adjust the output from 1m3/h to 3m3/h. If the output volume increases when spraying starts, the material can block the delivery of the delivery hose. The high-pressure water pump is used to supply high-pressure water to the nozzle assembly. The pressurized water enters the nozzle through the water ring and is atomized so that the material and water are evenly mixed. The needle valve of the new pre-humidification nozzle assembly can precisely adjust the amount of water added. It can effectively reduce the amount of water added. What’s more, unlike the nozzle tip of a typical nailer, the new nozzle tip is more flexible and reduces bounce.
