The dry type shotcrete machine, as the name suggests, the sprayed material (concrete, cement, etc.) added to the hopper is dry, the pressure is applied by the air compressor, and the dry material is sent to the nozzle, and the nozzle has an inlet pipe and a dry material. It is mixed with water at the nozzle and then ejected.
The wet spray machine is an anchor spray support equipment with good comprehensive performance such as reducing dust, reducing rebound and saving materials at home and abroad. The basic principle of the wet spray process is to add the water-mixed finished concrete to the wet spray machine and transport it to the nozzle. After the accelerated coagulant is added, the bundle is sprayed onto the construction surface.
The spray slurry added by the dry sprayer is dry, such as concrete, cement, etc., without adding water or adding a small amount of water, only adding water at the nozzle. The wet sprayer adds a well-mixed mixture, such as concrete, cement and water, and then sprays it out.
Since the dry sprayer is made of dry concrete or cement, the spray head needs to be filled with water to ensure the spray effect and not generate too much dust. The wet sprayer uses water to fully mix the concrete or cement, and then sprays it, and no water is needed at the nozzle, and no dust is generated, which ensures the working environment.
