If you are referring specifically to the nozzle tip that rotates to create a circular spray pattern (acting like a "brush" covering the surface), you might be looking for a component rather than a whole machine.
Double-Nozzle Rotor: Some advanced wet shotcrete systems use a double-nozzle rotor attachment at the end of the robotic arm. As it rotates (360°), it sprays concrete in a continuous, overlapping pattern, effectively "brushing" the concrete onto the rock. This ensures uniform thickness and reduces rebound.
Automatic Nozzle Rotators: These are attachments that can be fitted to the end of a shotcrete hose or robot arm. They use hydraulic or pneumatic motors to spin the nozzle head at a controlled speed while the operator controls the direction.
If you are looking for a specific manufacturer's model number or need details on the spraying capacity (m³/h) or arm reach, please let us know!
