High and Low Speed Disperser

The high-low speed disperser drives a serrated impeller to rotate via a motor-driven shaft, creating high-speed shear flow and axial circulation within the container. It utilizes hydraulic shear force to break down particle agglomerates, while the low-speed setting also serves a mixing function. It is suitable for the dispersion and emulsification processes of pigments and fillers in the coatings and ink industries, as well as for pre-dispersing small batches of materials in laboratory settings.
Selection
When selecting, consider matching the material viscosity with the motor power, and determine the shaft length based on the container depth. Explosion-proof requirements correspond to explosion-proof motor configurations, and corrosive media require stainless steel contact components. Variable frequency speed control adapts to different process stages, while anchor-type impellers balance dispersion and mixing functions. The working volume is typically 60%-70% of the container capacity.
