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.
-
Hinged Cover, 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.
-
