The difference between wet shotcrete machine and dry shotcrete machine: In principle, dry spray is put into the spray machine after the mixture (not containing water) is mixed, add water to the spray head, and then spray out under wind pressure; Spray is put into the sprayer after the mixture (water) is mixed, accelerate the coagulant at the spray head, and then spray out under the effect of wind pressure.

The use of concrete wet shotcrete machine:

1. The dust concentration near the machine and outside the nozzle is greatly reduced, and the poisoning to workers' health is eliminated.

2. The operating efficiency of the pump wet shotcrete machine can reach 10m3 / h, which greatly improves the construction efficiency.

3. Low rebound. Using a pump wet shotcrete machine to end wet spraying, the rebound rate can be reduced to less than 10%.

4. In wet spraying, because the water-cement ratio is easy to control and the degree of hydration of the concrete is high, the quality of sprayed concrete can be greatly improved and the homogeneity of the concrete can be improved.
