PZ Series Shotcrete Machine

The PZ concrete spraying machine uses compressed air to transport concrete mixture or similar loose materials with particles in a certain ratio through a pipeline, and then controls the addition of water and mixing at the port, and then sprays it at high speed onto the sprayed surface to solidify and harden, thereby forming a material protective layer of a certain strength.

It is widely used in the spraying and protection of protective materials for foundation pits, slopes, tunnels, bridges, mines, blast furnaces, and houses in projects such as construction, railways, highways, hydropower, greening, mining, and spraying of fire-proof, moisture-proof, and anti-seepage materials.

The structure and working principle of the PZ series concrete sprayer: the mixed material is discharged from the discharge port of the batching mixer (or manually mixed and loaded) into the vibrating hopper, fed into the hopper through the vibrating screen, and injected into the anti-sticking material cavity of the rotor by the material dispenser. It rotates with the rotor to the discharge port, where the compressed air introduced by the wind system blows the material into the cyclone. Here, another compressed air is introduced by the cyclone, which blows and accelerates the material in a multi-head wind spiral state, and makes it rotate and float, enter the feed pipe, reach the nozzle, and then add a small amount of water to spray it out.

The PZ series concrete sprayer is mainly composed of a drive device, a rotor assembly, a wind system, a spray system, and an electrical control box.
