The mixer completely solves the problems of low uniformity and dead angle caused by different specific gravity of materials, and adopts the mixing structure of five-axis mortar with flying knife to effectively disperse various short fibers. Dispersibility: The equipment can meet the production of dry powder mortar with different performance requirements. Such as masonry mortar, plastering mortar, polymer mortar required for thermal insulation system, polystyrene particle moisturizing mortar and other dry powder mortar. The vulnerable parts of the equipment are all made of high-strength wear-resistant steel. It has the characteristics of long service life. The equipment has obvious price advantage. Small investment and quick results. The device has a small footprint,
