Pneumatic blending is one of the quickest, cleanest and most efficient methods of obtaining homogenous batches of powdered, granular, or abrasive materials in transporters, atmospheric bins, or storage silos. Unlike a conventional blender, a pneumatic blender puts the user in control by providing the ability to customize a blending cycle that best suits the application.
Keep your materials moving
Choosing the correct method for flow enhancement requires several considerations. These include efficiency, headroom, material characteristics and price.
There are a few basic designs that are used to improve flow enhancement and while we offer vibration solutions, we specialize in aerating materials. Depending on the material characteristics, we believe that it offers the most efficient solution for flow issues. Both aeration and vibration are great models for head room restrictions but also provide a gentler approach for your material.
Encouraging your materials to keep flowing..Process blending..
When certain bulk materials are placed in containers, there can be issues moving the material to it’s destination. Nol-Tec has several proven flow enhancement techniques that successfully encourage the material to discharge from the container and keep your process moving.
Choosing the correct method for flow enhancement requires several considerations including efficiency, headroom, material characteristics and price.
While there are numerous styles to fluidize your material there are four basic designs to note:
The geometry of your hopper can be designed to promote material flow without any encouragement (example: steep angled hoppers)
Vibrators outside of the hopper are designed to jostle the material to the point of discharge; there are many designs of vibrators.
Mechanical flow enhancements are also available, either physically contacting the material or applying pressure to a flexible hopper.
Aerating the material to either change the material’s density, break the bond between materials, and/or break the bond between individual particles and the hopper wall.
With a pneumatic blender, you can mix batches of dry bulk materials in the conical hopper of a storage vessel or dense-phase pneumatic conveying transporter rather than in a mechanical mixer, yielding real savings in time, labor, and capital equipment costs.
Pneumatic blending in a bin or silo — that is, aerating materials with compressed air to mix them within the vessel — has been used for decades as a way to homogenize large production runs of a single material. For instance, cement producers inject compressed air through the floor of a flat-bottom silo to aerate various sections of the stored cement in sequence, changing the cement's bulk density to ensure that the discharged cement represents a wide range of the entire production run. Plastic pellet producers often continuously recirculate pellets from a silo's discharge area to the silo's top to mix pellets from yesterday's production run with today's pellets.
You can use the same pneumatic aeration technique to actively blend an entire batch in one mixing cycle by integrating a pneumatic blender (also called an
air blender
) into your material handling system. Because the blender provides mixing in your vessel or dense-phase pneumatic conveying transporter, it eliminates the need for a separate mechanical mixer. The blender also minimizes the material handling, reducing labor and equipment costs.
How the pneumatic blender works
Unlike a mechanical batch mixer, in which ingredients are measured and loaded into the mixer, mixed by a mechanical agitator or other mechanical means, and discharged from the mixer to a material handling system, the pneumatic blender is generally integrated
with
the material handling system.
The pneumatic blender is mounted at the bottom of the conical discharge hopper of a storage vessel, as The pneumatic blender is mounted at the bottom of the conical discharge hopper of a storage vessel, as
shown in Figure 1, or dense-phase pneumatic conveying transporter. The blender consists of a conical housing called a
blending cone
(or
cone casting
) that's mounted with several aeration valve assemblies. Each valve assembly includes an air cylinder and valve air seal and is connected to a compressed-air supply. The supply pressure to the valve assemblies is controlled by a regulator on the compressed-air supply's manifold. The valve assemblies are installed around the blending cone at different angles so they can inject compressed air upward into various areas in the hopper. An outlet valve, most often a pneumatically operated butterfly valve that's linked to the blender controls, is at the blending cone's bottom In operation, ingredients for the batch are fed one at a time by gravity or pneumatically into the vessel, forming layers. When the controls activate the blender, the aeration valve assemblies inject gentle pulses of compressed air through the blending cone into the center of the vessel's hopper section. The injected air expands in volume, aerating the material in the hopper bottom and gently lifting it. This aerated material now has a lighter bulk density than the material above it, causing the lighter material to migrate upward while gravity draws the heavier material downward (Figure 1). The interaction of the upward- and downward-flowing materials mixes the entire batch. The blending action is controlled by the air pulses' frequency, duration, and pressure. Because these pulse variables depend on the characteristics of each batch ingredient and the batch size, they must be determined by testing in the blender supplier's lab. Once blending is complete, the outlet valve opens and the batch discharges by gravity into the downstream handling system or process. When the blender is used on a storage vessel, the outlet valve ioften connected to a dense-phase conveying system because the system's low transport velocity will convey the blended batch without segregating it.
Controls.
Depending on the application, the blender can be controlled from a control panel at the blender or a remotely located PLC. Either can be preprogrammed with pulse settings for individual batches.
Optional aeration gas.
The aeration valve assemblies can also inject an inert gas, such as nitrogen, rather than air in blending applications with explosible materials, with materials that are sensitive to excessive amounts of oxygen, or in which the gas must contain no moisture.
Suitable applications
The pneumatic blender can be installed in the conical hopper of either a new or existing vessel. However, for a retrofit application, the existing vessel must have a hopper cone angle 60 degrees or steeper and must be structurally capable of withstanding the blending cone's weight and the pressure loading applied during blending.
The pneumatic blender is best suited to materials with an average particle size under ⅛ inch because these materials aerate easily. The pneumatic blender's gentle mixing action makes it especially suitable for blending batches containing friable materials, such as glass bubbles and spray-dried milk, whey, and clay powders. The blender is also well-suited to mixing abrasive materials; the unit's gentle action and few moving parts in contact with the material (including only the valve air seals in the aeration valve assemblies and the outlet valve) minimize the material's abrasive effects.
However, the blender's gentle action also typically makes the unit unsuitable for materials that require shear to become fully mixed. Some cohesive materials, such as titanium dioxide or iron oxide, aren't candidates for pneumatic blending because they don't aerate easily despite their fine particle size; the blender will simply blow holes through the material unless it's mixed with another material that promotes aeration. To determine whether the pneumatic blender can mix your difficult-to-aerate material, you'll need to have the material tested in the supplier's lab.

Nol-Tec’s Aerator – the difference
Aerators are utilized in the Fluidizing Bin Bottom and are a proven means of effectively and efficiently promoting flow and dislodging materials in silos, bins and chutes. Their “blast” of air fluidizes the material and disrupts bridging and rat-holing.
