Gunning machine manufacturer
As a professional gunning machine manufacturer, Leadcrete mainly produces dry shotcreting machines, wet shotcreting machines and other related products. The type of shotcrete machine is mainly divided into dry shotcrete machine and wet shotcrete machine. Our shotcrete machine is not only high in quality, durable, but also gunning machine cost is low. If you have any questions, we can solve them for you.
The working principle of dry shotcrete machine and wet shotcrete is as follows:
The dry shotcrete machine puts dry concrete into a hopper and presses air pressure through a hose to squeeze it out from the nozzle. Then, the nozzle operator adjusts the amount of water added to the nozzle to convert the dry material into concrete. When the material hits the surface of the body, it will rub the concrete completely. This allows the operator to control the amount of water put into the mixture, without the need to add accelerators for a more suitable batch process. If the process stops frequently in the application, we recommend this method. Wet shotcreting machine uses fully mixed concrete and transports it through hoses and nozzles without additional water. This is the most commonly used process because it has the advantages of rejection and less dust compared to dry shotcreting machines.
The gunning machine for sale is mainly dry shotcrete machine and wet shotcrete machine. There are big differences in the use of the two machines and the machine structure.
1. The difference between the moisture and dryness of the material
The material added to the dry shotcrete machine is dry concrete or cement without adding water or a small amount of water. The material added to the wet shotcrete machine will be a well-mixed material with a certain amount of moisture, such as a well-mixed mixture of concrete, cement and water.
2. Differences in working modes
The dry shotcrete sprays drier concrete and other materials, so when spraying, the nozzle must add water to ensure the spraying effect and avoid dust. The wet shotcrete machine mixes concrete and cement thoroughly with water, and then sprays. In contrast，the material sprayed by the wet shotcrete is moister, and the working environment is safer.
3. Operating environment and personnel safety
Due to the drying of the material, the dry shotcreting machine will produce a large amount of dust when spraying, which will endanger the health and safety of the operator. Wet shotcreting will greatly reduce the dust content when spraying, and because the materials have been mixed evenly, it will greatly reduce the amount of labor As a gunning machine supplier, we will provide you with satisfactory service. But if you want to get a suitable machine, please answer the following questions first:
1. What's the project you will use the machine do, for slope protect, or other? 
2. Do you need dry-mix shotcrete machine or wet-mix shotcrete machine?
3. What's the output you need, 3m3/h, 5m3/h, 9m3/h, or other? 
4. What's the maximum particle size of the material, less than 10mm, 15mm, or 20mm? 
5. About the engine, do you need air motor, electric motor or diesel engine, if you like the electric motor, voltage 3 phase, 380 V, 50 HZ is ok for you?
