The Visconomic+ high-performance bead mill (photo) was developed specifically for processing very viscous and temperature-sensitive products. The rotor and stator configuration maximizes cooling-surface exchange, resulting in a high cooling capacity. This enables the temperature of the product to be regulated during the grinding process so that excessive temperature increase is effectively avoided. As the product is well-cooled even with a higher power input, better dispersion quality can be achieved. The system's optimized grinding-gap width and the aggressive pin arrangement enable high throughputs, and optimum grinding results are achieved even with very viscous products. The grinding media are separated via a dynamic separating gap. Due to the constant shear in the gap, no particles can settle, which increases process reliability. — Bühler AG, Uzwil, Switzerland
