RIBBON BLENDER  RIBBON
BLENDER
VILAS' Ribbon blender is basically manufactured for uniform,
homogeneous, and quick mixing of powders and semi-wet materials of
different densities. Helical ribbon agitator design is the real key
for the success of this Blender.
How the Ribbon Blender Works -
A Ribbon Blender consists of a horizontal trough with a central
shaft and a helical ribbon agitator. Mixing results from the
turbulence induced by counteracting Ribbons. There are two sets of
Counter acting Ribbons - Outer Ribbon, Inner Ribbon. Both ribbons
mounted on the same shaft. Ribbons has close Trough clearance which
provides a region of high shear force near the wall thereby
achieving both bulk blending and dispersive mixing.
 Ribbons
are design to obtain complete and thorough mixing. It is designed in
such a way that along with vertical movement, material to be mixed
will have to and fro motion. Diametric size of the ribbon keeps some
proportion with the volume of the vessel so that the power required
to drive the machine will be less. The ribbon causes all the
material to circulate using only 5% of the power needed by the
turbine.
When the economy of the mixing equipments are taken into
consideration the ribbon blender is the best suited machine for
better result in the field of chemical, pharmaceutical and allied
industries.
The machine is manufactured in the combination of Mild Steel and
Stainless Steel. The product to machine contact parts will be in
Stainless Steel and remaining is in Mild Steel to reduce the total
cost of the machine. cGMP models are also available.

Special Features of Ribbon Blender -
-
Ribbon
cross-section and pitch, close clearances between outer ribbon
and shell, and number of spirals on the ribbon are the few
features which can be varied to accommodate materials ranging
from low-density finely divided materials to fibrous and sticky
materials.
-
The Ribbon
Blender is adaptable to batch or continuous mixing.
-
HEATING or
COOLING JACKET as per process requirements.
-
CHOPPERS -
Choppers can be provided as a Delumper or as a Fine Grinder.
-

Dependable Discharge Outlet.- Manual lever or hand wheel
operated slide gate valve, swing-type flush mounting plug valve
-
Discharge - Hand
wheel operated slide gate valve, gates, drop bottom, seals and
finishes
-
The PADDLE design
is optional and normal applied where FRIABLE materials are being
blended and when batches as small as 15% of the total capacity
are going to be mixed in one blender.
-
Optional Scale
hoppers are available
-
Constructed of SS
316, SS 304 and Carbon Steel.
-
Capacity - 25 Ltr.
to 7,500 Ltr.Fast, Easy Cleaning - The entire ribbon assembly is
removable as a unit.
-
Shaft Seal -
Three rows of packing, of type compatible with product and
application, housed in a standard gland follower stuffing box,
assist in keeping dirt out and product in. Purged and lubricated
seals as well as the mechanical seals are also available.
-
Simplified Drives
- Typically units of sizes to 100 cu. ft (2.8 cu. m) and 15 H.P.
