　　HSP-7Wet concrete spraying machineIntroduction and application scope:

　　Wet type spraying machine for minesThe series is a type of concrete spraying machinery mainly used for wet spraying of concrete. Wet spraying can make the mixture evenly mixed, accurately control the water cement ratio, and facilitate the hydration of water and cement. Therefore, it has low dust, low rebound, good concrete homogeneity, and high strength. ButWet type spraying machine for minesIt is a new generation of machinery specially developed for the construction of shotcrete in mines, tunnels, culverts, subways, hydropower projects, underground engineering, and coal mine tunnels.

　　HSP-7Wet concrete spraying machinemain advantages

　　1. Greatly reduced the dust concentration near the machine and outside the nozzle, eliminating the harm to workers' health.

　　2. High productivity.

　　three Wet type spraying machine for minesLow rebound rate. During dry spraying, the rebound rate of concrete can reach 15% -50%. By using wet spraying technology, the rebound rate can be reduced to below 10%.

　　4. During wet spraying, due to the easy control of water cement ratio and high degree of concrete hydration, the quality of sprayed concrete can be greatly improved, and the homogeneity of concrete can be enhanced. However, during dry spraying, the water cement ratio of concrete is adjusted by the spraying operator based on experience and visual observation, and the quality of concrete largely depends on whether the operator operates correctly.

　　HSP-7Wet concrete spraying machineWorking Principle:

　　The mixed material is fed into the machine hopper through the vibrating screen from the discharge port of the mixer (or manually mixed and loaded), and is then moved by the feeder into the direct feeding chamber of the rotor and rotated with the rain to the discharge port. Compressed air is introduced from the air chamber here, blowing the material into the discharge elbow. Another wind pressure is introduced by the cyclone, which disperses and accelerates the material in a multi head wind spiral state, causing it to float. The material is transported to the nozzle and then added with a small amount of supplementary water or quick setting agent (when wet spraying) to be discharged.

　　HSP-7Wet concrete spraying machinePreparation before operation

　　1. Check if the sprayer is in good condition and run it with no load when powered on. Tighten the friction plate and ensure that there is no air leakage.

　　two Wet type spraying machine for minesBefore spraying, rinse the rock surface with high-pressure water (it is strictly prohibited to rinse the rock surface with high-pressure water for soft, broken, and expansive surrounding rocks, and compressed air can be used to remove rock powder and gravel).

　　3. Check if the feeding pipe is damaged, and replace it if it is damaged.

　　4. Connect the Feng Shui pipeline, open the air and water supply valves, check the air pressure and water pressure, and check whether the Feng Shui pipeline leaks air, water, and is unobstructed. If there are any problems, they should be dealt with in a timely manner.
