HIGH SPEED DISPERSER
HIGH SPEED DISPERSER
Homogeneous dispersion of solid particles in a liquid is typically required for various applications in the process industry. For example, in the paint industry, various colour pigments are added in the liquid solvent in order to achieve a homogenous solution in the form of paint as the final product. Such pigments, which are solid particles, are not easily soluble in the liquid solvent and therefore require to be homogeneously dispersed in it.

Further, such pigments or solid particles are required to be broken down into smaller pieces to achieve homogeneous dispersion. Typically, such dispersion is achieved by exerting a shearing force onto the solid particles present in the liquid. However, conventional mixers used for dispersing solid particles in the liquid do not produce a homogeneous mixture of the dispersed solid particles in the liquid. The presence of undispersed solid particles, like pigments in the liquid causes nonhomogeneous mixing, thereby affecting the very cause for which the mixture is to be used.
High-speed dispersers can create the desired vortex along with the rigorous turbulent flow. The solids are charged into the vortex zone such that they are immediately dispersed. Depending on the depth of the vortex, the disperser blade i.e. MCD Cowl Disc can be positioned on or off centre. As the fluid viscosity changes, the operating speed of the cowl disc can be varied through an external VFD to maintain the vortex and to improve the dispersion efficiency. High-speed dispersers can have one or two dispersion impellers based on the tank geometry.
High-speed dispersers need to be carefully designed from the mechanical perspective since the operating speeds are generally higher ranging from few hundred rpm to 2,800 rpm. Such machines need to be low on vibrations, shaft runout and deflection. Hence, the shafting must be with high precision, balanced and controlled tuned shaft. Our efficient manufacturing processes help us achieve these mechanical performances.
MIXION – HISD comes with optional features and varied scope on drive arrangement (direct, belt drive), lifting arrangement (mechanical, hydraulic, pneumatic), safety interlock for avoiding starting if no vessel, VFD panel for speed adjustments and trolley mounted tanks. Surface finishes as desired for the wetted part can be offered to suit the applications.
