Mini Shotcrete Machine
Injection Operation Method of Mini Shotcrete Machine:
After the preparation work is completed, the mixing material can be added to the machine. The machine buckle author should first open the main valve, open the valve of the upper air pipe 1/3 turn, and then adjust the lower air pipe (pressure air to the cyclone) to about 0.05-0.1mpa no-load air pressure (depending on the conveying distance). Then the sprayer opens the sprinkler valve to wet the surface of the rock mass. At this time the operator can start the machine, began to spray concrete work. Now the working pressure is about 0.2-0.4mpa. According to the water-cement ratio of mixing material and the length of conveying distance, adjust and determine the wind pressure leading to the cyclone, and open the upper air pipe valve again until there is no more material leaking out of the machine's residual air port.

Operation Method of Mini 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.
