What are the main differences between wet concrete spraying machine and dry concrete spraying machine?

Concrete shotcrete machine is a mechanical device, it is through the compressed air concrete in accordance with a certain proportion of mixed together, and then sprayed into the concrete surface, the formation of dense concrete on the surface, so as to achieve the support of concrete. Concrete shotcrete machine is the key equipment of shotcrete, with high degree of mechanization, simple process and high production efficiency, it has been widely used in construction, municipal, railway, mining and other fields.

Concrete injectors can usually be divided into two types, one is concrete, one is concrete, the other is cement, one is cement, and the other is cement.

1. Concrete wet spraying machine is a kind of concrete blasting technology widely used in the world at present. It will produce a lot of dust, nozzle, inaccurate control of water and ash, insufficient cement spray and so on.

2. The concrete wet spraying machine can fundamentally solve the above three problems, namely: the dust concentration sprayed by the wet spraying machine is less than 8%, the rebound rate is not more than 10%, the water cement ratio is accurate, the concrete is fully hydrated, and the concrete spraying strength is high.

3. Compared with the concrete dry spraying machine, the concrete wet spraying machine saves a lot of costs, and the wet spraying dust is less, which ensures the health of the workers.

4. The thickness of the concrete wet spraying machine is easier to meet the construction needs than the concrete dry spraying machine, which can not only ensure the density of concrete, but also ensure the smooth surface, and greatly improve the quality of support.

With the improvement of environmental protection awareness and the continuous improvement of the quality requirements of shotcrete, more and more concrete wet shotcrete machines are used in the anchor shotcrete support project.
