rotorstatorsekoituksen

Rotorstatorsekoituksen, often translated as rotor-stator mixing, is a process utilized in various industries, particularly in chemical and mechanical engineering, to achieve efficient mixing of fluids. This technique employs a specific apparatus consisting of a rotor, a rapidly rotating component, and a stator, a stationary component with internal vanes or slots. The interaction between the rotor and stator generates intense shear forces and turbulence, facilitating the dispersion of different phases or the homogenization of a single fluid.

The fundamental principle behind rotor-statorsekoituksen lies in the high-speed rotation of the rotor within the confined space of the stator. As the rotor spins, it draws fluid into the mixing chamber and then expels it radially outwards through the openings in the stator. This action creates a powerful pumping effect and, more importantly, imparts significant kinetic energy to the fluid. The fluid then passes through the narrow gaps between the rotor and stator, where it experiences extreme shear and extensional forces. These forces are highly effective in breaking down agglomerates, dispersing solid particles, emulsifying liquids, and creating fine droplets.

Rotor-stator mixers are known for their ability to achieve a high degree of mixing in a short period, often surpassing the efficiency of conventional stirred tanks for certain applications. Their design can be varied, with different rotor and stator configurations tailored to specific mixing tasks, such as high viscosity fluids, or applications requiring particle size reduction. The effectiveness of rotor-statorsekoituksen is dependent on factors including rotor speed, rotor-stator gap size, fluid properties, and the geometry of the mixing head.
