喷浆机是矿井巷道最常用的支护设备之一,目前矿井安全生产常用的喷浆机以干喷机和潮喷机为主,虽然国内许多科研单位对湿式喷浆机的研发已有很长时间,但是目前尚未有成熟、稳定和高效的湿式喷浆机被矿井生产广泛接受。目前,湿式喷浆机主要以柱塞泵或挤压泵等实现喷浆过程,将物料送入密闭的气体压力输送系统的。 Spraying machine is one of the most commonly used supporting equipment in mine roadway. At present, the commonly used shotcrete machine for mine safety production is mainly dry spraying machine and tidal spraying machine. Although many domestic research institutes have a lot of research and development on wet spraying machine For a long time, but no mature, stable and efficient wet shotcrete machine is widely accepted by mine production. At present, the wet shotcrete machine mainly to achieve the plunger pump or squeeze pump shotcrete process, the material into the closed gas pressure delivery system.
