Axial flow agitator has good convective circulation capacity and certain turbulent dispersion capacity. It is suitable for mixing, dispersion, particle crystallization, reaction, dissolution, solid-liquid suspension, heat transfer and other operations. The structure with stabilizer is an improved form of this kind of turbine, which is mainly used near the critical point of shaft design and where the shaft needs radial centralization. The three frame blade scraper agitator is operated in laminar flow to prevent the deposition of heavy components at the bottom. It is suitable for crystallization, extraction, washing and other processes, as well as the heat transfer process of high viscosity liquid.
