1.Fed the dry mixture into the open hopper/ barrel of the shotcrete. To avoid clogging, provide liners on the chamber to lessen lumps of dry mixture.
2.With the control, allow the dry mixture to be blown by the compressed air into the spraying hose nozzle.
3.As the dry mixture pass the nozzle, control the separate water nozzle to hydrate the dry mixture with the right amount of water
