Many blenders utilize internal agitators to enhance the mixing process.
Various types are manufactured for specific purposes. Gemco's agitator
designs offer the highest degree of effectiveness. Blending is enhanced
in any shape vessel with an internal agitator installed. The agitator
provides the ability to de-lump, disperse minute quantities of dry
or liquid materials, and blend large batches very rapidly.
Gemco cantilever agitators are designed to withstand material impact.
The assembly features an agitator disc and dispersion blade combination
that is sized according to vessel size and application.

Slow Speed
Improved blending without attrition can be accomplished by using the
Slow Speed agitator. Long, slow moving agitator blades allow load
level variation and reduced seal wear. Suitable for breaking down
soft lumps and blending minor additives, it can also be used for de-lumping.
Typical blade tip speed is 1700 feet per minute. This design typically
does not require a vented cover.
High Speed
Suitable for pigment and difficult dispersions as well as breaking
down lumps, densifying and intimate blending of minute additives.
Typical blade tip speed is anywhere from 1,650 to 3,300 feet per minute.
This option normally requires a vented access cover.
The vented cover relieves any pressure that is created by the High
Speed agitator. Without this, the pressure can push powder into the
seal area prematurely and cause seal failure.
Ultra High Speed
Gemco's Ultra-High Speed Agitator can be operated for longer periods
of time as the extended blades allow for high tip speed without generating
excessive heat at the shaft area. Blade tip speed is up to 5,000 feet
per minute.
Used for high intensity blending, the Ultra High Speed allows rapid
blending of large batches. It's also used for pigment blending, it
eliminates streaking and a final milling operation in many applications.
This option normally requires a vented access cover.
The Sanitary Blade and Disc Option
The Sanitary Agitator-Blade and Disc is a one-piece design that allows
for faster and easier cleaning. For those industries where cross contamination
and bacterial growth cannot be tolerated, this construction is invaluable.
Gemco's Sanitary design improves productivity and reduces labor. With
this one-piece system, the costly and non-productive time required
to disassemble the individual blades, washers, nuts and bolts (32
to 64 individual components in conventional agitators) is eliminated.
This eliminates final screening of product due to missing blades,
nuts and bolts. Also, this design eliminates crevices where product
can get caught. |
