Concrete Shotcrete Machine is divided into dry mix shotcrete machine and wet mix shotcrete machine according to differents praying process. With dry gunning the material is discharged from the machine with a maximum of 5% moisture and then feed materials to the nozzle assy by an air stream where the required water, typically 5–10%, is added.
With wet shotcrete machine the gunning material is moistened with water in a mixer in advance and then pumped through a hose by means of an eccentric screw or a piston pump. At the end of the line the material is dispersed with compressed air and, if necessary, an additional liquid bonding/hardening agent can be added (shotcreting), usually need add accelerator.

For dry mix shotcrete machine, usually be used in outdoor project, such as bridge repair, swimming pool, slope-protection etc.
While wet mix shotcrete machine, widely applied in indoor project, such as mining, tunnel, subway etc. project. Compared with dry mix shotcrete machine, wet mix shotcrete machine most are used in more important projects, low dust, low rebound, high spraying strength. Whichever kind shotcrete machine, all need air compressor to provided compressed air.
