This machine is a kind of screw type with high pressure mortar spraying machine, advanced technology, operation and simple maintenance, no special training, can be proficient in operation. This machine is mainly used for building internal and external wall, cement mortar spraying and the outer wall insulation mortar spraying, refractory coating. Artificial rivers and launch the white wall machine, main drawback is that the density of cement mortar and the wall and mortar is low, we introduced the spraying equipment of large flow, high pressure, customer service for the above defects, slurry density is much higher than the standards prescribed by the state, avoids because of quality, time limit for a project, wages and other issues caused by the trouble. Multi-usage, can spray mortar, waterproof coating, refractory material, is not subject to regional and environmental conditions and the influence of the coating surface shape.
