3. About
Octagonal Blender (OB), due to its octagonal shape is designed to process larger volume of
material. It occupies less space compared to other similar blenders like 'V' and Double
Cone.
Power consumption is also less. The blending takes place at low speed during operation. It
is well balanced even in higher capacities. It is very useful for wherein gentle blending of
dry granules of powder is to be done. It is a slow speed blender and has removable type
baffles mounted on a rectangular shell.

4. The important feature of the machine is easy to wash in place. Octagonal
blender is supplied with a bin charging system or can be designed for vacuum
charging.
Dust free charging system is also incorporated, which is a completely closed
system for charging and discharging of powders or granules.
The power consumption is comparatively lower than other similar type of
blenders. The machine basically consists of shell welded with conical Octagonal
shape ends and supported with sturdy supports on both side.

5. One hand side shaft is connected to a standard gearbox by means of chain and
sprockets, which in turn is coupled to an electric motor. The whole drive
assembly is covered with S.S. side panel.
The inside portion of Octa body is mirror polished and the outside surface of
Octa body; frame & guards are matt polished. The material to be mixed is
charged in machine either manually from top or bin charging system or
vacuum charging system and then the port is locked positively.
Then blender is started to preset blending time. At the end of process, machine
is stopped and the product is transferred to process containers by opening the
butterfly value. All contact parts are made out of SS 304/ SS 316 or SS 316L
quality material.

21. Material of Construction

22. Octagonal
Blender
Working

23. Blenders are used for mixing, lubricating and blending in Pharmaceutical, Nutraceutical,
Food, Chemical, cosmetics, ceramics, pesticide, plastics and other Allied industries
Two third of the volume of the cone blender is filled to ensure proper mixing. The octagonal
shape blenders have six corner of product container for more tumbler effect to the material
for fast and homogenizing mixing. It can perform homogenously dry mixing of free flowing
powders, granules requiring low shearing force, Mixing and Blending of particles with rapid
intermixing of particles irrespective of varying specific gravities.
The material is loaded into the blender drum. The octagonal blender is tumbles the material
in the container and spread out. Blender gives best result for granules due to very slow speed
and octagon shape of container. The mixing is achieved in 5 to 15 minutes with better
homogeneity.
