Compact Structure Wet Type Concrete Gunite Machine Water Cement Ratio
Concrete Gunite Machine
Structure of Concrete Gunite Machine:
The material can be stirred into the straight through chamber of the rotor and rotated to the discharge port with the rotor, and the material is sent to the cyclone through the compressed air of the air chamber through the rotor.

Operation Method of Concrete Gunite 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.
