Philippines Atimonan Project
Production capacity ：3-20m³ /h
System pressure：22MPa
Working wind pressure: 0.4-0.6Mpa
Maximum diameter of aggregate: 15mm(shotcrete)/30mm
Description
P20 is 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
send the dense flow material from the conveying pipe to the mixed flow pipe.
The compressed air forms a thin stream and is sent to the nozzle through the
pipeline. A certain proportion of accelerator is added to the nozzle and sprayed
directly on the sprayed surface; grouting directly sends the dense flow
material to the pouring body from the conveying pipe.
