The refractory gunite shotcrete machine uses compressed air to spray out a certain proportion of refractory materials at high speed to form a refractory layer on the surface of the sprayed masonry. Because of its rapid spraying construction speed, high efficiency, and good engineering quality, it is widely used, mainly suitable for: thermal gunning of the refractory layer of industrial furnaces and kilns. It is mainly suitable for concrete spraying and supporting construction such as tunnels, culverts, subways, hydropower projects, underground projects, mine roadways, and highway slope protection. And the thermal gunning operation of the refractory layer of industrial furnaces.
Now, let's learn some operation of refractory gunite shotcrete machine. A portion of the spray water is added a few meters from the nozzle by prewetting and premixed by relying on turbulence within the vehicle. However, this approach is prone to operational problems. For example, if too much water is added ahead of time, it can lead to clogging, especially in rapid bonding systems where the inside of the hose begins to harden. Too much water will reduce the quality of refractories and refractory life. In addition, water can decompose into hydrogen in liquid steel, which can be harmful to some steel grades (microcracks). Using standard mixing heads (for dry spraying), water is sprayed through radial holes, and to compensate for insufficient initial wetting, the operator often works.

Use excess water to reduce dust. However, this often results in the use of incorrect water-cement ratios, thus reducing the durability of the refractory. Improvements are achieved through the use of a pressurized high pressure pump that makes the water jet sharper and easier to reach the center of the nozzle cross section.

Leadcrete equipment has many years of experience in the field of refractory gunite shotcrete machine for Chinese refractories spraying machine manufacturers. Refractory gunite shotcrete machine is designed for refractory dry mix shotcrete applications as well as concrete shotcrete applications.

With the refractory gunite shotcrete machine that we produced, you can get a low dust and high performance spray flow in the nozzle. The refractory gunite shotcrete machine that we produced is equipped with a variable output drive, so the start output can be adjusted to a smaller size through the frequency conversion to avoid congestion.
Features of refractory gunite shotcrete machine:
1. Variable output driven by frequency conversion;
2. Collect dust bags;
3. Clean and dust removing gun;
4. Heavy duty solid wheel.
