It consists of a trough mounted on a stand. In the trough a ribbon like conveying scroll is attached to a shaft. The ribbon may be continuous or interrupted. The shaft is operated by an electric motor. The trough is semicircular, with lid.
It can be tilted on the stand to remove the material. When the motor is started the material gets mixed due to convection and shear. Two ribbons, with opposite direction may sometimes are attached to the shaft. A mixture of high homogeneity can be produced by prolonged mixing, even when the components of a mixture differ size, shape, density or have a tendency to aggregate.
This Machine has been developed for mixing of various types of granular products. The machine is efficient and versatile used in mixing and lubrication processes in various industries. Some of the main industries of use include pharmaceutical production, food industries, chemical processing and also making of cosmetic products.
Octagonal Blender equipment has an octagon shaped body with a rectangular central portion. It is equipped with baffles that enable fast and efficient mixing as well as rapid charging and discharge ports with suitable butterfly valves. The equipment is highly suitable for areas where gentle blending of dry granules or powder is required.
The V-blender considered has suitable diameter sections separated by an angle of 60o, and is rotated at a medium speed and "V" shape of container. The blend is achieved by the constant dividing and intermeshing of particle movement provided by two connected cylinders.
The rotation of the blender produces a splitting and refolding action on the material during each revolution. The V-blender is good for blending dry powders and granulated products. Absence of shaft projection eliminates product contamination.
This type of mixer is designed in such a way that the vessel imparts movement to the material of mixing by tilting the powder until the angle of surface exceeds the angle of repose.
Thus powder bulk or particles slide and get mixed in the vessel. It rotates on central shaft. Shape of cylinder comes in two truncated cones joined together by cylinder section. A tight closing lid of the fast closing type for feeding material and a discharge butterfly valve at the other end of the unit which also renders a perfect tightness. Baffles are provided in bigger unit for intense mixing.
During the process of mixing particles of powder of mixing particles of powder hit each other and wall of the mixer resulting mixing action. However speed of mixture is very important. It should run at critical speed. Too high or too low speed will definitely affect the mixing process.
The blender is recommended preferably when the products to be mixed have a similar density and particular size as well as no lumping properties. Over loading of mixer with powder material should be avoided. There should be sufficient room for powder to move in drum. Critical time for mixing can be set by withdrawing the samples from mixer at interval of time and analyzing it for homogenicity.
