concrete spraying equipment for underground excavation engineering

The electric motor pea gravel concrete spraying machine is used for important concrete spraying project, like hydraulic engineering, tunnel project, mining engineering, etc. Considering that some customers is not easy to get electric supply in working site, we have air motor and diesel engine drive wet shotcrete machine for option.

The long working life wet and dry pea gravel shotcreting machine works on the principle of pneumatic transport of concrete mixture, it is divided into dry mix shotcrete machine and wet mix shotcrete machine according to different adding water process.
