Heavy-duty, high-torque double planetary mixers operated under comparatively low speeds are ideal for processing shear-thickening mixtures.
- Effectively disperse fibers into your viscous mix.
Many fiber-filled composites are high viscosity formulations that require efficient dispersion in a planetary mixer configuration where a number of blade designs and combinations are available. Fiber characteristics and composite rheology are the main factors evaluated in the mixer selection process.
- Hybrid planetary mixers
produce high viscosity mixtures with ultra-fine dispersion quality.
Hybrid planetary mixers are utilized for creating fine dispersions in viscous mixtures, typically within the viscosity range of 100,000 to 2 million cP. Intense mixing is applied to the product by constantly advancing a high speed disperser and a low speed stirrer into the batch. Solids are quickly incorporated into the viscous bulk material and agglomerates are dispersed regardless of product flow characteristics.
Designs for multiple planetary stirrers and disperser blades are available for more demanding applications.
