We often encounter problems of this kind in the daily operation of shotcrete machine. Our shotcrete machine suppliers has summarized these issues in a small way, as follows.
1. The pressure of the conveying air flow is too low. If this is the case, we should immediately stop the motor and the air supply line. If the rotor is blocked during the stoppage, we should disassemble the inlet and outlet ducts and clean the material cavity with a brush.
2. The particle size of the aggregate is too large. In this case, we should stop the rotation of the machine, close the gas path valve, then remove the feeding pipe from the elbow, and open the gas path valve, and then blow out the rotor's stock, and then check the transport If the pipe is blocked, finally connect the feeding pipe to the elbow and blow it out with compressed air.
3. The cross section of the air inlet pipe is small, and the air supply volume of the pressure fan is small. At this time, we should replace the large air duct and large-capacity compressor.
4. The moisture content of the dry mix is too large. At this time, we should close the air valve, clean the elbow and the rotor cavity, and minimize the water-cement ratio of the mixture.
