The working principle of the dry spraying refractory shotcrete machine is to put the refractory material into the vibrating hopper, pass through the screen and enter the straight-through material chamber of the rotor, and rotate with the rotor to the discharge port, where it is blown into the rotary by the compressed air from the upper wind path. Then the cyclone introduces another stream of compressed air, which blows and accelerates the material in a multi-head spiral state, and makes it rotate and float, enters the delivery pipe, and mixes with water to spray the sprayed surface when it reaches the nozzle.
When the high efficient mining castable gunite machine is working, the refractory material is added to the vibrating hopper, enters the rotor through the screen, goes straight to the material chamber, and rotates with the rotor to the discharge port, where it is blown by compressed air from the upper air path.
The brand new concrete gunite machine refractory gunite shotcrete has good mechanical properties, no noise, high construction efficiency, low cost of accessories, simple maintenance, time-saving, labor-saving, high efficiency, and labor-saving.
Before the refractory shotcrete machine is officially sprayed, we should first spray the spray gun, adjust the ratio of material to water, and check the degree of uniform mixing, so that there is no dry material or flow on the sprayed surface.
The dry mix spray refractory gunite shotcrete machine uses compressed air to transport refractory materials or similar loose materials through pipelines, control the mixing of water at the end door, and then spray them on the sprayed surface at high speed to condense and harden, thereby forming a material protection layer with a certain strength.
