PZ-7D concrete dry shotcrete machine is a device for spraying concrete, which has the characteristics of advanced technology, reasonable structure, stable performance, convenient operation and maintenance, and long service life. PZ-7D concrete dry shotcrete machine is widely used in sprayed concrete construction of tunnels, culverts, subways, hydropower projects, and underground projects.

Working principle of PZ-7D concrete dry shotcrete machine

The stirred materials are unloaded into the vibrating hopper through the discharge opening of the batching mixer (or manual mixing and feeding), and then fed into the hopper of the spraying machine through the screen, which is dialed into the direct feed cavity of the rotor by the dialer. With the rotor rotating to the outlet, the compressed air passing through the air chamber blows the material into the cyclone. Here, another wind is introduced by the cyclone, and the material is blown, accelerated, rotated, floated, enters the feeding pipe in a multi-headed spiral state, and reaches a nozzle, and then a small amount of supplementary water is sprayed out.
