construction wet mix concrete spraying machine
The construction wet mix concrete spraying machine is belong to thin flow shotcrete machine, adding compressed air in the materials outlet. While pump type shotcrete machine is belong to thick flow shotcrete machine, adding compressed air in the nozzle.
The construction wet mix concrete spraying machine uses hydraulic pumping S valve structure, two oil cylinders reciprocating motion alternately to pump concrete from conveying pipe to nozzle, add compress air to wet shotcrete machine outlet and add a percentage of the accelerator at nozzle, concrete slurry be sprayed to surface directly.
The pump type wet shotcrete machine output could be adjusted continuously: main oil pump is variable displacement plunger pump, spraying volume could be adjusted freely. Accelerating adding quantity could be adjusted continuously: according to concrete spraying volume adjust step-less.
