 Double
Agitator Mixers from Andritz Sprout deliver outstanding performance in slurry applications,
such as mixing grain water and recycle in ethanol production, and dryer conditioning applications: mixing
wet cake, syrup, and dryer recycle for corn gluten feed and DDGS (Dried Distillers Grains with Solubles),
as well as similar products. In dryer conditioning applications, DA Mixers produce a flowable dryer feedstock
having a minimum of wet or unwetted lumps that can adversely affect dryer performance.
DA Mixers are also in use in a myriad of industrial and food processing applications.
- Proven in severe duty applications worldwide
- Unique agitator design mixes quickly and thoroughly, enhancing fermentation and other processes
- Adjustable speed, retention time, and mixing intensity
- Machine design puts less stress on shafts, for longer life
- Compact design – can be installed in low headroom situations
Unique Agitator Design Dual agitator shafts have adjustable paddles mounted on a
helix, assuring that product being blended is always being moved toward the discharge, regardless of
paddle adjustment. Fifty percent paddle overlap assures intensive cross mixing action. Under these conditions,
paddle adjustment affects bed depth and retention time. With a dual shaft configuration, product bed
level can be maintained all the way to the discharge – not fall off as product seeks its own angle
of repose, as is typical in single shaft and non- intermeshing designs.
 Compact Integral
Drive Standard Motor mounted directly above the reducer keeps the
footprint compact. Motor and drive can also be mounted in different configurations, especially for high
horsepower applications. Drive and reducer can be mounted on either end. The drive can be shipped as
a unit, completely assembled with belt drive installed. This ensures accurate measurements and fitting,
and saves time in installation. Simple V-belt primary drive permits easy speed adjustments to control
mixing action and retention time. A simple gearbox, integral to the drive train, converts a single input
to dual output. This indexes the shafts so turning is identical, assuring consistent mixing action. Dual-output
oil-bath gearbox can be completely removed without disturbing the mixer shafts, enabling easy periodic
maintenance. The gearbox has lip-type oil seals, vented oil filler, and visual oil level indicator.
Couplings and Bearings Rigid couplings support the shafts and transfer axial and
radial loads to the gearbox, so that the gears and bearings act as a bearing for the mixer shaft on the
drive end. This design reduces stress on the shafts and contributes to longer life. On the opposite end,
block bearings mounted outboard of the mixer trough prevent lubricants from contaminating mixed product
and allow space for packing gland-type shaft seals. Coupling design accommodates slight shaft bend or
misalignments, and enables the gearbox to be removed without disturbing shaft seals.
Trough contour minimizes product residue and eliminates the “Dead Zone” in
the bottom of the mixer. Special finishes are available. Materials of construction include 304 or 316
stainless, for corrosion resistance.
