Air duct cement concrete Wet Mix Shotcrete Machine advanced technology
Wet Mix Shotcrete Machine
Structure of Wet Mix Shotcrete Machine:
The structure and working principle of wet mix shotcrete machine: the mixing material is discharged into the vibrating hopper by the mixing material mixer's discharge port (or artificial mixture and charging), and the sieve is fed into the jet feeder hopper through the screen.

Operation Method of Wet Mix Shotcrete Machine:
After the preparation work is finished, the mixing material can be added to the machine. The machine operator should first open the main valve, the valve of the upper air duct opens 1/3 circles, and then adjust the air pressure of the lower air duct (to the cyclone) to about 0.05-0.1 MPa (depending on the delivery distance). Then the sprayer opens the nozzle valve and gives the wet rock surface. At this time, the operator can start the machine and start shotcreting. Now the working pressure is about 0.2-0.4 MPa. According to the water-cement ratio of mixtures and the length of conveying distance, after adjusting and determining the wind pressure to the cyclone, the upper air pipe valve is opened again until there is no more material leakage at the machine outlet.
