TK700 Wet Shotcrete Machine
- PRODUCT DETAIL
TK700 Wet shotcrete machine can only spray wet mixed concrete.Different with rotor type , TK700 adopts piston type feeding system,making wet concrete flow in the machine evenly and no blocking . Concrete and steel fiber all workable. Less wearing parts and more stable.
TK700 Wet Shotcrete is widely used in mine,tunnel,hydro power,soil nail project,slope supporting,etc.

TK700 has two sets conveying systems.
One is a concrete conveying system, the finished concrete mixing from the concrete mixer enters from the shotcrete machine hopper and evenly sent to the air-material mixing bin through the feeding system. And after being mixed with the high-pressure air, it will become rarefied flow state then pass through the injection pipe to the nozzle.
The other is the liquid accelerator addition system, which adjusts the flow rate of the metering pump according to the content of the liquid accelerator. The liquid accelerator is mixed with the high pressure air through the atomizer, atomized to the mixing ring of the nozzle and mixed with the concrete in the rarefied flow state, and sprayed from the nozzle to the spray surface.
