V Blender is manufactured and supplied by us in Thane, Maharashtra. A V blender is a very popularly used blender in many pharmaceutical and food factories, owing to its ability to efficiently lubricate, mix and blend ingredients. The V blenders manufactured in our Thane unit, are also commissioned at many chemical, pesticide and plastic industries. These specially designed units do not have any packing glands that enter the chamber, and thus prevent any cross contamination. The advantages of using V blenders are that it is easy to clean, charge and discharge, can be used for delicate materials and prevents product contamination.
Construction and Operation :
The V-Blender is made of two hollow cylindrical shells joined at an angle of 75° to 90°. The blender container is mounted on trunnions to allow it to tumble. As the V-blender tumbles, the material continuously splits and recombines, with the mixing occurring as the material free-falls randomly inside the vessel. The repetitive converging and diverging motion of material combined with increased frictional contact between the material and the vessel's long, straight sides result in gentle yet homogenous blending.
The primary mechanism of blending in a V-Blender is diffusion. Diffusion blending is characterized by small scale random motion of solid particles. Blender movements increase the mobility of the individual particles and thus promote diffusive blending. Diffusion blending occurs where the particles are distributed over a freshly developed interface. In the absence of segregating effects, the diffusive blending will in time lead to a high degree of homogeneity. V-Blenders are therefore preferred when precise blend formulations are required. They are also well suited for applications where some ingredients may be as low as five percent of the total blend size. Normal blend times are typically in the range of 5 to 15 minutes depending on the properties of material to be blended.
The charging of material into the V-Blender is through either of the two ends or through the apex port. Studies on V-blenders have demonstrated that for solid powders which have similar size and shape, there is no mechanism to move the powders across the line of symmetry of the blender. For such materials, care must then be taken to load each side of the blender equally to ensure the desired homogeneity of blends.
Blending efficiency is affected by the volume of the material loaded into the blender. The recommended fill-up volume for the V-Blender is 50 to 60% of the total blender volume. For example, if the fill of material in the blender is increased from 50% of the total volume to 70% of the total volume, the time taken for homogenous blending may be doubled.
Salient Features
Easy to clean.
Material of construction is SS 316.
Integrated Vacuum loading option available.
Intensifier bar can be provided for special applications.
Particle size reduction and attrition are minimized due to the absence of any moving blades. Hence it can be used for fragile materials.
The Bin charging system can also be incorporated in it which provides complete dust free closed environment for charging and discharging.
The shape of blender body results in a near complete discharge of product material, clearly an added advantage over horizontal blenders.
The absence of shaft projection eliminates product contamination.
V-blenders are easy to clean. Internal attachments like lump breakers and liquid dispensers widen the applications of this blender.
Capacity available from 5 -1200 L (Higher capacities upto 16000L also provided on demand).

Applications of V-Blenders : V-Blenders designs are most often used for the dry blending of free flowing solids. This blender is often used for pharmaceuticals, but the mixing action's slight shear limits the blender's use for some very soft powders or granules. V-Blenders are generally used for the following :
Pharmaceuticals
Food products
Milk powder
Coffee
Dry flavors
Ceramics Powders
Pigments
Pesticides and Herbicides
Plastic powders
Animal feeds
Spice blends
Fertilizers
Baby foods
Cosmetics
Polyethylene
