Working principle of KPZ-4 shotcrete machine for dry material:
KPZ-4 shotcrete machine is a commonly used shotcrete equipment for dry spray and dump material. It is deeply popular in customers. Let's learn about the working principle of KPZ-4 shotcrete machine.
Mixed concrete is fed from the agitator discharging outlet through the vibrating screen to the spraying machine’s charging hopper. Or it can be realized by human labour to mix and feed the materials. Then, concrete mixture is moved by a poker to rotor through chamber. And it is transferred to discharge outlet along with the movement of rotor. The compressed air from air chamber blows the mixture to outlet elbow in the rotor. Another blow of compressed air from the rotational swirler will further scatter, accelerate and rotate the mixture to the conveying pipe. Finally, concrete mixture is sprayed out through the nozzle where a little water is added.
