structure and working principle

The PZ series concrete shotcrete machine uses compressed air to continuously transport concrete along the pipeline and spray it onto the construction surface. There are two types of dry jets and wet jets. The former is pneumatically conveyed dry-mixed material, mixed with pressure water at the nozzle, and then sprayed out; the latter is delivered by pneumatic or concrete pumps and the concrete mixture is sprayed out through the nozzle. It is widely used in lining construction of underground projects, shafts, tunnels, culverts, etc.

The structure and working principle of the PZ series concrete shotcrete machine: the mixed materials are fed into the hopper of the jetting machine from the discharge port of the mixer (or manual mixing and feeding) through the vibrating screen, and the material injected into the rotor is moved by the shifter In the straight-through material cavity, the rain swirls to the discharge port, where compressed air is introduced from the air chamber to blow the material into the discharge elbow, where another wind pressure is introduced by the cyclone, which is a multi-head wind spiral. The state blows up the material, accelerates, rotates, floats, enters the conveying pipe, and reaches the nozzle to add a small amount of supplementary water) or the liquid accelerator is sprayed out.

PZ series concrete shotcrete machine is mainly composed of driving device, rotor assembly, air duct system, spraying system, electrical control box and other parts.

PZ series concrete shotcrete machine features: straight-through rotor type non-adhesive cavity, smooth discharge, saving time; four-point elastic compensation and compression, good sealing effect, less dust next to the machine, long life of wearing parts; low-pressure high-speed vortex Cyclone air conveying overcomes the problems of adhesion, pipe blockage and pulse separation during material conveying, and the material flow is uniform, continuous and stable.
