Hot sale concrete shotcrete machine
After years of technological innovation and continuous improvement and optimization, Wodetec hot sale concrete shotcrete machine has formed its own product features. According to the different injection technology, the Wodetec hot sale concrete shotcrete machine can be divided into dry mixed concrete shotcrete machine and wet mixed concrete shotcrete machine. When using a dry mixed concrete shotcrete machine, the material drains up to 5% of the water from the machine, then the material is sent to the nozzle assembly by air flow and the required water is added to it (usually 5-10%). In a wet mixed concrete shotcrete machine, the lance material is previously wetted with water in a blender and then pumped through a hose through an eccentric screw or piston pump. At the end of the line, the material is dispersed with compressed air and, if necessary, other liquid bonding/hardener (sprayed concrete) can be added, usually with the addition of a promoter.
How to distinguish between dry mixed concrete shotcrete machine and wet mixed concrete shotcrete machine? When distinguishing the two kinds of concrete shotcrete machine on site, it can be seen that the dry mixed concrete shotcrete machine adds dry concrete or cement during the work, so when spraying, the nozzle needs to add water to ensure the spraying effect, and the dry concrete jet machine The main advantage is that the conveying distance is long, the equipment is simple and durable. However, since it mixes the dry mixing concrete nozzle with water, the construction dust and rebound are large, the quality of the spraying is poor, and it will affect the site environment and interfere with the normal operation of the operator. Usually, dry mixed concrete shotcrete machine is used for slope protection outside the project, swimming pools, bridge maintenance, etc.
In the wet mixed concrete shotcrete machine, the concrete or cement is fully mixed with water, and then sprayed. No water is needed at the nozzle, and no dust is generated. Wet mixed concrete shotcrete machine can make the mixture mix evenly, the water-cement ratio can be accurately controlled, and it is beneficial to the hydration of water and cement. Wet mixed concrete shotcrete machine is the anchor with better comprehensive performance such as reducing dust, reducing rebound and saving materials at home and abroad. The preferred equipment for spray protection and blast furnace injection. It is often described as a green cleaner. Compared with dry and tidal spray machines, it has the advantages of small dust, less spray rebound, protection of working environment, saving of raw materials, improved spray quality, and easy operation and maintenance. Staff requirements are relatively low. Wet mix concrete shotcrete machines are mainly used for indoor projects such as tunnels, mines, subways and boiler grouting.
Wodetec is the leader of the industry, our company produces the concrete shotcrete machine has sales around the world, and by domestic and foreign customers consistent high praise, Wodetec's research and development team after a long hard study developed concrete shotcrete machine performance is stable, and on this basis, the development of the new type WSZ3000V dry and wet mixed concrete shotcrete machine, combined with the dry mixed concrete shotcrete machine and wet mixed concrete shotcrete machine, the advantages of mixed with variable injection quantity, the advantages of good sealing, stable flow smoothly. Due to the adoption of more advanced technology and structural design, the machine is easier to operate and maintain, with better performance and longer service life.
