YG shotcrete machine for sale is a new type of high-efficiency shotcrete machine, The equipment uses a concrete pump to transport concrete to the nozzle of the manipulator through a pipeline and uses compressed air with the accelerator to spray the concrete onto the wall of the roadway to be sprayed. It has a reasonable structure, humanized design, reliable performance, convenient operation and maintenance, and long service life. No dust, low noise, and low rebound rate when working. This machine greatly reduces the dust concentration near the machine and the nozzle and improves the working environment of workers. Click here you can check our shotcrete machine for sale.

Characteristics of Shotcrete Machine for Sale
- Simple structure and strong adaptability.
- The pumping pressure is high and the spraying distance is long.
- High efficiency: large conveying displacement and high comprehensive work efficiency.
- High performance: The sprayed concrete has high performance, compactness, uniformity, and high strength.
- Accelerating agent addition and control technology: the famous brand metering pump measures accurately, and the atomizing jet is mixed with nozzle materials to make the accelerating agent and concrete mix evenly.
- Reduce the dust concentration beside the machine and outside the nozzle, and eliminate the harm to workers’ health.
- Low resilience. When dry spraying, concrete resilience can reach 15%-50%. Using wet spraying technology, the resilience rate can even be reduced to less than 10%, effectively saving costs.
- The hydraulic oil is cooled by air cooling, which is simple and environmentally friendly.

Concrete Shotcrete Machine Classification
The different methods of adding water to the concrete mixture, can be divided into three types: dry shotcrete machine, wet shotcrete machine, and semi-wet shotcrete machine. They have different sizes, and we can easily distinguish them through the hopper. Send your requirement to us if you need to buy a shotcrete machine for sale.
- The dry shotcrete machine mixes cement, sand, and small stones in a certain proportion, and mixes them evenly. The compressed air is blown to the nozzle and mixed with the pressure water from the pressure water tank before spraying. The construction method in this way is simple and fast, but the dust is too large and the rebound loss of the ejected material is large.
- The wet shotcrete machine enters the jetting machine with a water-added concrete mixture. Therefore, the dust content in the spray is low, and the rebound amount is also reduced, which is an ideal spray method. This machine can not only improve construction conditions but also reduce raw material consumption. But the wet material is easy to condense in the material pipeline, causing blockage and trouble cleaning.
- The semi-wet type is also called the tide type, which can reduce the dust content in the air to less than 2mg/m^3, that is, the concrete mixture is a moisture content of 5% to 8% (by volume). Dust is reduced during spraying. Because it has less adhesion than wet materials, it does not stick to the tank. It is an improved method of dry and wet.
The Main Difference Between Wet and Dry Shotcrete Machines
- Different shotcrete modes
Because a dry shotcrete machine or cement is added to the dry shotcrete machine when spraying, the nozzle needs to add water to ensure the spraying effect and not generate too much dust. The wet shotcrete machine uses water to fully mix concrete or cement and then sprays it. There is no need to add water to the nozzle, and no dust is generated, ensuring the working environment.
- Different requirements for staff.
A dry shotcrete machine will generate a lot of dust during the spraying process. It is relatively harmful to the environment and is very harmful to the health of construction workers. dry shotcrete machine is not conducive to underground construction operations. The job of a dry shotcrete machine requires more operators.
The slurry of the wet sprayer is mixed in advance. It does not take up a lot of manpower and does not generate dust. It is less harmful to the environment and workers and can be used in various working environments.
- The degree of dryness and wetness of the slurry is different
The spray slurry added by the dry shotcrete machine is dry, such as concrete, cement, etc., without adding water or adding a small amount of water. The wet spraying machine adds a homogeneous mixture, such as concrete, cement, and water, and then sprays it out.
- Different conveying distances and prices.
The maximum conveying distance of the dry shotcrete machine can exceed 200 meters. However, the spray distance of wet shotcrete is slightly weaker. The price of a dry shotcrete machine is cheaper than that of wet spraying concrete equipment.
