Detailed operation of shotcrete machine feeding : 1, The prototype made in attendance Restructuring seat body, in which the body and then add a section attendance to the mounted accelerator hopper and a round screen, there is a semi-enclosed and open to the discharge port. 2, Accelerator funnel fixed superstructure middle bucket lid can be opened, before running the accelerator bag upside down on the hook bucket lid, accelerator can fall freely under the wing rotating dial material will quick-setting agent dial to the bottom edge of said bucket overflow, the quantity can be adjusted gauge adjustment. 3, Round siter greater than 20mm classifying stone according to incoming cases, the discharge interval, sieve under the spring can produce vibrations, so set aside chunks of material stuck without wings, wings once when dialing material cards, insurance ;the sieve bottom cut off, so that the shotcrete machine body to be protected, to be shut down to remove the large pieces, put the pin back, now you can resume operation of the shotcrete machine.
