Many customers were confused about the difference between shotcrete machine and grouting machines, had an error occurred in the device selection, not only more than the cost of transport also allows customers not to work in a timely manner. Well, let’s learn about the distinction between spraying machine and grouting machine together Shotcrete machine: spraying machine is mainly by the driving device, rotor assembly, wind path system, jet system, electric control box, explosion-proof motor without control box).The spraying rod is composed of a nozzle, a handle and a switch. Lime slurry by the conveying hose pump into the hollow handle, operator through the switch to control the injection quantity and according to the length of the spraying position adjustment handle and operation. Grouting machine: high pressure grouting machine is a kind of high pressure chemical grouting, and it is easy to move. It completely solves the dependence on traditional hand pressure air as power and inconvenience of carrying heavy machinery; structure design is scientific and simple without special training can repair, and added a new human self suction feeding system using single liquid chemical grouting material of professional models, a super high pressure does not need air pressure source, construction speed is quick.
