Wet Shotcrete Machine
We developed this heavy‑duty concrete spraying unit by referencing mature overseas machine designs. Lots of adjustments were made during our design phase, so the machine can handle various tough site conditions found on domestic construction projects. Both core components and overall frame have been reworked to suit real‑world local operation requirements.

We developed this heavy‑duty concrete spraying unit by referencing mature overseas machine designs. Lots of adjustments were made during our design phase, so the machine can handle various tough site conditions found on domestic construction projects. Both core components and overall frame have been reworked to suit real‑world local operation requirements.
We use custom high‑wear‑resistant material for its rotor and stator. Fluid dynamic simulation helped us fine‑tune their special profile shape. As material moves through these parts, pressure pulses stay minimal. Output pressure and material flow remain stable during operation. Common issues from standard sprayers, such as fluctuating pressure, sudden feed loss and pipeline clogging, are greatly reduced. The machine can run continuously for long hours with solid reliability.



Features
A built‑in planetary mixing assembly comes as standard. Multi‑axis movements create mixed stirring paths. Inside the mixing chamber, concrete slurry produces both radial and axial convection flow. Unlike many ordinary mixers, you will hardly see unmixed dead zones. Output material keeps good uniformity and workability. Sprayed layers gain high density, with very few voids or delamination defects.
The machine is compact and light in weight. Site staff can shift it around short distances without much trouble. You do not need heavy lifting gear or large transport equipment. It works well even in confined spaces, for example inside tunnels and underground mines.
Key load‑bearing components and all friction‑heavy wearing areas have gone through wear‑resistant strengthening treatment. Compared with most ordinary models on the market, this unit delivers better anti‑wear performance and longer service life.
It fits a wide range of site‑work applications. You can use it for building facade reinforcement spraying, primary tunnel support, slope protection together with anchor reinforcement, road and bridge foundation treatment, as well as underground mine support spraying. It helps construction teams boost working efficiency, reduce follow‑up maintenance work and bring down overall project costs.
