Courtesty of Myers Engineering, Inc.Д«y creating perpetual batch movement, viscid material (from 10,000 to 150,000В cP and above) can be thoroughly mixed while maintaining a low-shear environment. Forward facing teeth accelerate product with minimal impact shear. For glass microsphere-filled products, it is essential to minimize shear forces, which can be damaging to the hollow glass microspheres and ultimately lead to an increase in product density from theoretical ideals.ДЇigureВ 11.3. Blade selection is also not well understood, and there are types of blades that should be used for one type of process yet not another. While this speed is required for particle size reduction and deagglomeration, it is by no means necessary or efficient when used in blending applications, or in applications that contain shear-sensitive components. More than 90% of people within the industry believe that a proper tip speed for a disperser is 5000В FPM. Unfortunately, despite all the technologies currently available, most companies-regardless of how big or small-do not properly apply the different types of dispersion. Various impeller designs and configurations are used, depending on the batch viscosity and processing requirements for components within the batch.
