Concrete Spraying Machine

Maintenance of Concrete Spraying Machine:
1. Anti-stick cavity and discharging elbow with anti-stick function, generally will not bond at work, but after the end of each shift should open the rotor, elbow check and clean;
2. Frequent attention should be paid to the maintenance and maintenance of the reducer;
3. After each shift, the mixing material and other sundries adhered to the outer surface of the reducer shall be cleaned in time;

Operation Method of Concrete Spraying 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.
