High Shear Mixers

The advent of rotor/stator mixers revolutionized mixing technology. Imparting vigorous radial and axial flow patterns and intense shear, SPM High Shear Mixers accomplish a variety of processing objectives including homogenization, emulsification, powder wet-out and deagglomeration. SPM High Shear Mixers are used throughout many industries, including the pharmaceutical, food, cosmetic, ink, adhesives, chemicals and coatings industries. For challenging applications, SPM also offers advanced rotor/stator configurations: Ultra High Shear Mixers capable of producing very fine emulsions and dispersions that traditionally require processing in an expensive colloid mill or high pressure homogenizer. Available in batch and inline designs, many popular laboratory and production models are available from stock.




Series 100 Batch High Shear Mixer

How the Series 100 Batch High Shear Mixer Works

The Batch High Shear Mixer design consists of a single stage four-blade rotor that turns at high speed within a stationary stator. As the rotating blades pass each opening in the stator, they mechanically shear particles and droplets, and expel material at high velocity into the surrounding mix, creating intense hydraulic shear. As fast as material is expelled, more is drawn into the bottom of the rotor/stator generator, which promotes continuous flow and fast mixing. The batch model can be either mounted to a vessel or suspended over a vessel on a portable lift. The mobile configuration offers the flexibility to use a single mixer in multiple vessels. It also allows the user to vary the position of the stator to process different materials and batch sizes. The rotor/stator of the batch model is generally positioned 2 - 3 head diameters off the bottom of the vessel, and slightly off center. To ensure adequate suspension of heavier solids, the rotor/stator generator may be positioned in the center of the vessel. Interchangeable stators provide unlimited flexibility to adopt to a variety of product formulations. Batch models are supplied in many sizes from 3/4 through 100 horsepower




Series 500 Batch High Shear Mixer

How the Series 500 Batch High Shear Mixer Works

The Batch High Shear Mixer design consists of a single stage four-blade rotor that turns at high speed within a stationary stator. As the rotating blades pass each opening in the stator, they mechanically shear particles and droplets, and expel material at high velocity into the surrounding mix, creating intense hydraulic shear. As fast as material is expelled, more is drawn into the bottom of the rotor/stator generator, which promotes continuous flow and fast mixing. Series 500 High Shear Mixers include a mechanical seal above the shaft and an ANSI flange to allow the mixer to be anchored to the top of an enclosed vessel. Suitable for either atmospheric or vacuum/pressure mixing, these mixers are designed for applications that require an extra measure of protection against contamination. The rotor/stator of the batch model is generally positioned 2 - 3 head diameters off the bottom of the vessel, and slightly off center. To ensure adequate suspension of heavier solids, the rotor/stator generator may be positioned in the center of the vessel. Interchangeable stators provide unlimited flexibility to adopt to a variety of product formulations.




Series 200 Inline Rotor Stator Mixers

How the Inline Rotor Stator Mixers Works

The Inline Model High Shear Rotor-Stator mixer design consists of a single, dual or four stage rotor that turns at high speed within a stationary stator. As the rotating blades pass the stator, they mechanically shear the contents. The Inline model is a good choice for process lines that require frequent changeover from one product to another. A simple valve can divert finished product downstream or switch instantly from one vessel to another. Interchangeable rotor-stator combinations provide unlimited flexibility to adopt to a variety of product formulations The Inline models are supplied in many sizes and materials of construction from 1/2 through 150 horsepower.



Series 300 Ultra High Shear Inline Models

How the Ultra High Shear Inline Models Works

Our Ultra High Shear Models include the Quad,X Series or MegaShear Designs. The units include four stage or greater rotors that turn at speeds to 15,000 feet per minute within a stationary stator. As the rotating blades pass the stator, they mechanically shear the contents. This series is a good choice for process lines that require frequent changeover from one product to another. A simple valve can divert finished product downstream or switch instantly from one vessel to another. The Inline models are supplied in many sizes and materials of construction from 10 through 250 horsepower.



Series 400 High Speed Powder Induction-Batch

How the High Speed Powder Induction-Batch Works

Powders like fumed silica, calcium carbonate, titanium dioxide, gums, thickeners and many pigments are difficult to wet out. Even with a strong vortex in an open vessel, they resist wetting out, and often float on the surface for hours. Our new SLIM technology enables you to wet out powders almost instantly. The SLIM system sucks solids directly into the high shear rotor-stator where they are immediately wetted out and dispersed into the liquid stream. SLIM shortens the mixing process and eliminates dusting-thereby minimizing the volume of airborne particles released into the plant atmosphere. SLIM systems are supplied for installation into existing vessels or as complete stand alone turnkey systems.


Series 600 High Speed Powder Induction-Inline

How the High Speed Powder Induction-Inline Works

The rotor/stator generates an intense vacuum and sucks in powders and liquids into the rotor-stator area. A feed tube adjacent to the back of the rotor provides a path to inject solids directly into the stream. The solids are combined and mixed into the flowing stream at the same point, the mixer is capable of handling extraordinarily large volumes of solids without clogging.
