Advantages of wet Mortar Spraying Machine:
1. The wet Mortar Spraying Machine greatly reduces the dust concentration beside the machine and outside the nozzle, and eliminates the harm to workers' health.
2. High productivity. Dry concrete shotcrete generally does not exceed 5m3/h. When using a wet Mortar Spraying Machine, it can reach 10m3/h when working manually; when using a manipulator, it can reach 20m3/h.
3. Low resilience. When dry sprayed, the concrete resilience can reach 15%-50%. The rebound rate can be reduced to less than 10% using wet spray technology.
4. During wet spraying, because the water-cement ratio is easy to control and the concrete has a high degree of immobilization, it can greatly improve the quality of shotcrete and improve the uniformity of concrete. Adjusted according to experience and visual inspection, the quality of concrete depends to a large extent on the correct operation of the machine operator.
