MDT-20D Shotcrete Machine
It's a kind of mechanical equipment that can be both shotcrete and grouting .the shotcrete uses the thrust generated by the hydraulic pump to make two oil cylinders alternately move back and forth to sedn the dense flow material from the conveying pipe
to the mixed flow pipe. the compressed air forms a thin stream and is send to the nozzle through the pipe line.
A certain proportion of accelerator is added to the nozzle and spayed directly on the sprayed surface
grouting directly sends the dense flow material to the pouring body from the conveying pipe.
