High Viscosity Mixers

Dual-shaft mixers blend and fold the mass in the vessel and improve product uniformity by scraping the walls. Multi-shaft mixers are most often used to mix medium to high-viscosity products.

A high-speed disperser alone has a limited zone of influence in viscous products, so the low-speed blade is necessary to achieve a homogeneous mixture. When equipped with scrapers, the low-speed blade also aids in heat transfer.

Applications

• Used in the making of printing inks, sealants, caulks, hot melt adhesives, magnetic media slurry, creams, lotions, toothpastes, etc.

The dual-shaft configuration will handle most Multi-shaft mixing jobs. Because it has separate mixing shafts, maintenance is easier on a Dual Shaft than on a Concentric Shaft mixer.

The HOCKMEYER Difference.

Our multi-shaft mixers are designed by an experienced engineering staff incorporating information from customers, our own R&D Laboratory, and data from decades of HOCKMEYER Multi-shaft mixers in service.

Our standard low-speed blades, for example, use a triangular cross-section, which is both strong and presents a wide profile for efficient mixing action. This design is stronger than a blade made from flat bar and easier to clean than a blade with circular structural elements. Our low-speed blades move product efficiently at relatively low peripheral speeds and typically require less horsepower than our competition’s mixers. Lower tip speeds mean longer life for scrapers.

HOCKMEYER machines have a reputation for performance and reliability. That is by design.
