Multi Shaft Mixers
Multi shaft mixer is a multi purpose/function mixer which is widely used to make toothpaste, cream, ointment, lotion and emulsion in cosmetic, pharmaceutical, food and chemical industries. Ginhong is a professional multi-shaft mixer supplier in China manufacturing all kinds of multi shaft mixers and blenders.
What is a Multi-Shaft Mixer?
Single-shaft emulsifier mixers face a common limitation- viscosity. When the material viscosity is too high, localized heating may occur in the blade area and product mixing becomes inefficient. Meanwhile, material near the mixing tank walls become stagnant and doesn’t get mixed at all. The mixing shaft may also buckle or deform due to the intense force received by it.
Ginhong’s Multi-Shaft Mixers are used suitably for very high viscosity mixing applications. They are composed of two or more independently driven agitators working in tandem.
Ginhong manufactures two configurations for Multi-Shaft Mixers; the LZ Dual Shaft Mixer and the SZ Triple Shaft Mixer.
The LZ Dual Shaft Mixer is used for materials with viscosities ranging from 1 to 500,000 centipoises such as putties, chewing gums, and soaps. On the other hand, the SZ Triple Shaft Mixer is used for materials with viscosities ranging from 1 to 750,000 centipoises.
How it Works?
The Multi-Shaft Mixer works with mixing materials with laminar mixing process rather than turbulent mixing. This means that the rotates at a slower speed or RPM than other conventional single-shaft mixers.
This working principle of the multi-shaft mixer is adapted to thoroughly distribute the various materials and eliminate any pockets of dry materials.
During operation, the high viscosity, heavy product is forced into the working zone of the high shear blade movement of the low-speed blade that disperses and dissolves the materials.
The mixing unit is also equipped with Teflon scrapers which cleans the mixer walls while in operation and aids in heat transfer to an external jacket.
Ginhong Multi-shaft mixers (Dual Shaft and Triple Shaft) use a triangular cross section blade, 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.
The 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.
Mixers all comply with Current Good Manufacturing Practice (CGMP) regulations enforced by the FDA. CGMP is vital for quality control of manufacturing plants as it entails proper design, monitoring, and control of manufacturing processes and procedures.
Adherence to the CGMP regulations assures the identity, strength, and quality of manufacturing operations. CGMP also establishes strong quality management systems, robust operating procedures and investigating product quality deviations.
Eliminates Flow Isolation
Studies show that Multi-shaft mixer configurations are more efficient in eliminating flow isolation because of the wider area of mixing.
More aggressive Mixing
Multi-shaft Mixers agitators are more aggressive than Single Shaft Mixer agitators and provide an accurate mix in a shorter period of time. These make it better for extracting protein from material source.
Elimination of voids
Multi-shaft Mixers offered by Ginhong processes mixing applications under vacuum, which is beneficial for certain adhesives and sealants to develop higher densities and achieve better tensile properties as a result of improved shearing and contact of the different components.
Ginhong manufactures a wide variety of mixers with a great range of viscosities and applications. Their extensive range of pumps and process systems are designed to withstand extremities when delivering efficient metering, processing and analyzing.
Faster Mixing Times
Multi-shaft mixers have smaller mixing times compared to the single shaft configuration
Prevents Material Bridging
Multi-shaft Mixers prevent bridging and roll-back by distributing the product evenly. This is beneficial as it prolongs equipment life and prevents microbial growth in the equipment
Used in the making of printing inks, sealants, caulks, hot melt adhesives, magnetic media slurry, creams, lotions, toothpastes;
Highly filled formulations such as soy-based adhesives, cement pastes, urethane sealants and other caulking compounds;
