Mining tunnel industries Dry Mix Shotcrete Machine with air compressor
Dry Mix Shotcrete Machine
Description of Dry Mix Shotcrete Machine:
Shotcrete machine has two different types: dry-mix and wet type.
1. Dry shotcrete machine can only spray dry material.
2. Wet shotcrete machine can spray dry material or wet material
3. Shotcrete machine uses concrete pump to convey concrete through
pipeline to the nozzle of manipulator, and uses compressed air with
accelerator to spray concrete to the wall of shotcrete roadway. It
is widely used in various working environments, such as tunnels,
culverts, subway, hydropower projects, underground projects, slope
protection and high methane mine roadways.

Operation Method of Dry 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.
