1.  What Is V-blender?


A V Blender Machine

It is a blending machine which is productive and all-round that homogeneously mix and lubricate dry powder.

Like the name suggest, this blending machine structure takes the shape of letter “V”.

2.  What Are The Main Parts Of V-Blender?

  • Cylindrical Twin Shells

Blending of material takes place in a container system formed by the shells.

The cylinders are 70° to 90° inclined and hollow.

For easy tumbling, join the container to trunnions.

Monitoring, loading materials and cleaning access points are on both cylindrical arms.

In the inside parts, it has a morror shinning finishing.

  • System For Discharge

At the bottom around 24 inches from floor or extra of cylindrical V shape shells is mixer’s discharge system.

The valves are enough for products withdrawal regulation.

To prevent wastage of material through spillage, secure seal is provided by the valves thus a neat environment to work on is maintained.

One of the valve mechanisms is manual operation, where valve is openned and closed manually.

The second mechanism is pneumatic operation which is for unloading and electric.

  • Control System Full Kit

It is made up of programmable logic control and control panel.

Numerous operations of machines are programmed by the PLC system.

In mixer operations, control system is key.

It includes; main power supply, start button, fuse, stop button incase of emergency.

3.  How Does V-Blender Work?

Connect the machine accurately before you start operation and ensure effective functioning of the system.

With straight forward and simple operation of blending using either of the two shells, load the materials.

A charging system bin may be included to get an operation that is free from dust.

If working with a PLC machine, it is an automatic style of loading drum.

Loading same shape, size and density powders care must be taken.

To attain a mixture that is homogenous, materials of equal portion is loaded in each cylinder arm.

Process of tumbling begins after completion of loading. Acting vessels for mixing are the shells.

Regular splitting and combining of the materials in the cylinders into two arms.

Under gravity action, material fall inside cylinder freely where the mixing take place.

Diverging and converging force is continuously produced on the component due to the gravity motion.

Interior walls with large vessels get in contact increasingly with the content leading to a blending that is uniform and smooth.

Diffusion is a significant technique during operation of blending in the vessel for a viable mixture achievement.

An Illustration Of How A V Blender Works

An Illustration Of How A V Blender Works

In a random motion engagement of solid particles in the shells is on as vessel goes on rotating.

Particles movement rise equally due to increase in rotation thus diffusive blending.

Depending on the blending material, there might be time variation, between 5 minutes to 15 minutes is the standard blending time.

Technique of diffusion under normal conditions leads to formulation which is precise and highly uniform.

Through the discharge port unload your desired product.

To release formulation, engage it accordingly considering the discharge valve used.

Use equipment that are preferred like barrel or drums for product collection.

The vessels V shape makes unloading easier.

Factors to consider when using a V blender machine:

  • The whole mixer capacity in the blender should be approximately 50% to 70% load volume.
  • To enable you take a short duration to achieve a mixture that is homogenous, capacity regulation is recommended by the manufacturers. These minimizes time hike.
  • Lower rate blending speed is recommended regulate speed to the rate of 50% to 80%, higher rates produce a lot of dust.
  • Inside the V blender there is no agitation. Rotation of the shell is caused by movement of powder until you obtain an optimum mixing.

4.  Where Can You Use V Blender Machine?

  • In food processing industries flavors and ingredients must be mixed properly to get good food.

Consistency of colour, appearance, texture and taste in what people consume daily is the key.

Not free flowing, density difference or materials with large particles also leads to long mixing time.

Another high influence is how loading of the mixer is done.

Mixing Batch Size

Standard mixer total volume is 40% to 70%.

Leaving free space in a rotary is very important, space for solids to roll over.

Organize trials to optimize blender filling rate for some mixtures when filling at 70%.

Mixer overfill will require high increase mixing time.

Speed Of Mixing

Supplier’s recommendation should be followed, instructions differ depending with the size of the blender.

23.  How Do You Calculate V Blender Capacity?

In the sense of the throughput the capacity of a V blender is in kg/h.

40-70% is the max filling rate of the blender water volume, time to load, mixing and discharge the blender.

Calculation of total cycle time (t) =L+M+D

The throughput (m) =V*r*ρ*60/t

t = total cycle time in min

L = loading time in min

M = Mixing time in min

D = Discharge time in min

m = throughput in kg/h

V = volume of water in m3

r = ratio of filling (0.4 to 0.7)

ρ = bulk density mix in kg/m3

Loading And Discharge

Disconnect the mixer from the rest of the process during mixing while the entire shell rotates.

To load and discharge the mixer manual operation is involved.

Located the blender to tipping station and discharge hopper to avoid dust emissions thanks to flexible.

Discharge Valves

Manually operated butterfly valve is the V blender discharge valve.


Mixer is not equipped by many instruments while rotating.

Mixing time and rotation speed control are limited.

24.  Which Are The Common V Blender Designs?

Asymmetrical design

Consider 2 possible cylindrical shells which differ in length hence asymmetrical blender.

Mixing from one shell to another by asymmetric design decreases mixing time thus reduce segregation.

Baffles positioned in the mixer help in asymmetric achievement taking note of drawbacks.

An Asymetric V Blender

An Asymmetric V Blender

Intensifier Bar

An agitator installed along the axis of the mixer and rotating at high speed is proposal of some manufacturers.

Mixing performance can be improved by intensifier bar bringing shear mixing with cohesive powders or mix having the tendency to agglomerate.

Mixer operator must take into consideration that product breakage will be created with such intensifier.
