The high shear grout mixer for mining well-engineering dam construction is special pulping equipment developed for grouting materials with a low water-to-binder ratio. It is mainly used in engineering construction of hydropower, railway, highway, construction, mining, and other industries. The high shear grout mixer for mining well-engineering dam construction can be quickly slurried when mixed with water. Compared with the general blade mixer, it has the characteristics of high pulping efficiency, simple operation, uniform slurry, and short-distance conveying function.
