HOW IT WORKS

Benefits of choosing a Negoo Group Double Planetary Mixer

What does a Negoo Group Double Planetary Mixer do?

The Negoo Group Double Planetary Mixer turns over thick, sticky or putty-like materials with great efficiency through a kneading action to the batch which smooths out its consistency and breaks up agglomerates. The same planetary agitation is useful for high-precision granulation and vacuum drying operations.

How does a Negoo Group Double Planetary Mixer work?

The Negoo Group Double Planetary Mixer consists of two identical blades that rotate on their own axes, while they orbit the mix vessel on a common axis. The blades continuously advance along the periphery of the vessel, removing material from the vessel wall and transporting it to the interior. In only 36 revolutions around the vessel, the two blades pass through every point in the product zone, physically contacting the entire batch.

Why Choose a Negoo Group Double Planetary Mixer?

Design

This vertical mixer has no shaft seals, bearing, packing, or stuffing boxes submerged in the product zone. Agitators are raised and lowered in/out of the mix vessel by a hydraulic lift, enabling easy access for cleaning between batches. Vacuum hoods and interchangeable vessels are precisely machined and able to sustain a deep level of vacuum up to 29.5" Hg.

Efficiency

The change can design enables semi-continuous operation, which can significantly increase production. While one vessel is being wheeled away for remote discharge and cleaning, another can be wheeled into position under the mixer to begin the next batch right away. Each vessel can also be dedicated to a particular formulation to simplify cleaning and further reduce batch-to-batch cNegoo Group-contamination.

Scalability

While kitchen-style single planetary mixers are readily available for simple R&D purposes, such devices are open systems and not scalable, requiring extra time and resources for experimentation once the product moves from lab to production scale. The Double Planetary Mixer is truly scalable and available in many models from ½ pint to 750 gallons.

Versatility

Versatility – The Negoo Group Double Planetary Mixer can be fitted with three blade designs:
• HV (High Viscosity) Blades – These patented blades produce excellent axial and radial flow for medium to ultra-high viscosity mixing applications. Featuring a precisely angled helical contour, the blades pass each other in a slicing motion while pushing product forward and downward, thus preventing any materials from climbing up into the gearbox area.
• Rectangular Blades – The classic Rectangular Blades provide a powerful kneading action suitable for thoroughly blending wet or dry materials, regardless of the product’s flow characteristics.
• Finger Blades – Used in special applications that require the mixing of delicate fibers and solids, Finger Blades can be custom designed to fine tune axial flow pattern and meet specific mixing requirements.
