V type mixer

1.What is V Type Mixer?

The V-type mixer- also known as ‘Twin Shell Mixer’ is one of the tumbling mixers broadly used in various production sectors involved with powder mixing. It is designed to mix granular materials in no time.

This machine is incredible as it perfectly performs the mixing process of dry powders homogeneously as it revolves. The shape of this equipment is designed as two inclined vessels or blenders joined at an angle of 70-90◦ to construct a v shape which makes mixing convenient.

2.What Does V Type Mixer Do?

V mixer achieves consistent mixing of solid particles either in the form of granules or powder. This machine is capable of mixing fine powder and even such substances that contain water. It is popularly used in the pharmaceutical industry for premixing in the granulation process and other industries utilize this equipment for various tasks of mixing.

If you’re wondering about mixing type, then the V-type mixer follows ‘Diffusive Mixing’, characterized by the small random motion of mixing particles ultimately promoting better mixing. V-type mixers are ideal where you’re required with precise, fast, and smooth outcomes as it typically leads to a high degree of homogeneity in five to fifteen minutes that is also depending upon the material’s property.

3.What Is The Industrial Scope Of V Type Mixer?

V-type mixers are commonly designed to deal with the dry mixing of free-flowing substances. That’s why it is used for unlimited applications in the industrial sector, such as:

Pharmaceutical Industry

V-type mixers are extremely important in the pharmaceutical industry because pharmaceutical companies have to make sure that they adhere to strict production guidelines and quality control. The medicines produced have to be of a certain purity, quality, and potency to ensure that they are safe to consume.

Food Industry

V-type mixers can also be used to mix dry powders, milk powders, cereals and spices in the food industry. It is especially used to make mixed spices since it has the ability to blend all the spices together till they form a homogenous mixture.

Paint Industry

The paint industry is involved in the manufacture of paint which is made up of pigments, resin solvents, and additives. V-type mixers blend the pigments, solvents, resins, and additives together to form a paste which is then thinned out with solvent to its final form.

Chemical Industry

The chemical industry is a broad manufacturing sector where products like pesticides, herbicides, laboratories, household cleaning items, etc., are dealt with routinely. A V-type mixer is of prime importance as it safely carried perfect mixing without causing health hazards.

Cosmetic Industry

Cosmetics are made from oils, dyes, and various kinds of pigments.  Whether producing lipsticks, foundations, or eye shades; the first step in its production is the melting of wax and oil together. The formed product is taken to the V-type mixer where it combines with the desired color pigment and a solvent. All of these constituents are blended for hours in the V-type mixer till a homogenous formula.

Agriculture Industry

The agriculture industry produces animal fodder with the help of a V-type mixer. The raw materials for fodder include vitamins, wheat, fruits, forage, minerals, corn, barley, etc. These materials are added in a V-type mixer till they are blended well and have acquired their final form.

4.What are the Important Components of V Type Mixer?

V Tank

This section supports the mixing of the formulation.

Feeder Points

Feeder point or hopper where mixing material to be mixed is poured.

VH Base

This part is comprised of the following components:

Motor

V Type mixer is mainly driven by a motor. It is considered a main component of the machine.

V- Belt

This is beneficial for power transmission, controlling vibrations, and ensuring stability during the procedure.

Drive Belt

It is associated with a set of pulleys and belts in order to produce torque and modulate the speed.

Control Panel

The brain of a machine; you can set the mixing time, speed, processing, and storing via the control panel.

Discharge Chute

This section enables the discharging of mixed material from the machine.

5.What is the Working Principle of V Type Mixer?

The working principle of V type blender is simple where the mixing barrel which is composed of two cylindrical barrels of unequal sizes rotates continuously.

Upon rotation, the mixing material mixes gently and segregates in the mixing barrel. A range of different potential energies and heights of material leads to creating a thrust in the material. The two hollow cylindrical shells correspond at the angle of 75° to 90°.

The base of the V blender is mounted on trunnions enabling the tumbling process as the machine moves. Here the mixing is carried out as the material free-falls randomly in the mixing vessel. Thus, the repetitive converging and diverging process of the material enhances frictional contact with particles and the wall of the mixer yet forms a homogenous mixture.

The particles move in a random manner resulting in diffusion mixing; there’s no chance of segregation effect as diffusion mixing is used.

6.How To Calculate The Capacity Of V Type Mixers?

V type mixers are usually quite standardized by manufacturers however they have varying specifications according to their ranges of volume of blender , capacity, power consumption etc.

The capacity denotes the throughput function of blender’s batch size , time required for mixing, loading time and discharge time.

The time consumed overall can be calculated by the formula : t=L+M+D and then the capacity can be finally deduced using : m= V×r×p× 60/t    where, L is the loading time , M is mixing time, D is discharge time , m is throughput, V is volumeof water, r is the filling ratio and p is the combined bulk density.

7.What is the Significance of V Type Mixer?

V-type mixers generally have lots of advantages in various industrial sectors. We will discuss some of its advantages below:

Production Of A Homogenous Mixture

The use of V-type mixers ensures that the product produced is homogenous and all its constituents are well blended together.

The complete closure of the V-type cylinders prevents the entry of any particles from the outside. This ensures the purity of the product inside and prevents its contamination.

Cost Effective

Most of these mixers are generally cheaper as compared to the other machines which are used in the various industrial sectors.

8.What Are The Demerits Of V Type Mixer?

Poor Mixing

It is quite difficult to mix granules completely in V-type mixers. Furthermore, it can be tricky to mix fine and light powdered particles into main powder blend. The light powder particles tend to float around due to high kinetic energy.

High Power Consumption

This machine uses gravity based diffusion for mixing of powders which require lifting and rotation of main vessel due to this power consumption of V type mixers is high.

Damage to Particles

Due to lifting of main mixing vessels, the powders get thrown around hence the shape of powder granules will be destroyed.

Tricky Installation

V type mixers occupy a larger floor space due to this it is quite difficult for operators to install these equipments.

9.Classification of V Type Mixer?

There are two types of mixers available to fulfill the production requirements. They are

Mini or Small V Type Mixer

This is ideal for small production lines. It has a manual or vacuum conveyor through which the powder enters the system. The rest operation remains the same. Due to the compact size of the machine, the powder that sticks in the corners of the machine is not easy to be removed.

Large V Type Mixer

Large V mixers are used for large-scale industries where freely flowing mixtures are carried out on large scale. The design of the machine remains the same as small v-type machines, but the only difference is productivity. These machines are much more economical due to their low maintenance and easy handling. Large V-type mixers can produce mixing up to a level of 6000 liters per hour.

10.What are the Major Technical Problems and Solutions of V-Type Mixer?

S.NO	PROBLEM	CAUSES	SOLUTIONS
1	Resistance during Operation	The resistance is due to no proper cleaning of high friction areas, or they are not timely greased.	Application of grease or cleaning those high friction areas can minimize this problem.
2	Knocking in Machine	Loosing of parts can cause this problem	Monitoring the tightness of parts and tight those which get loose
3		If the V Belt gets loose, it can also cause knocking	Check the V Belt and tighten it to the required tension.
4	Delay in Powder Mixing	No proper setting of operation time.	The setting of timers should be done according to the powder that is being mixed in a V-type mixer
5		V Tank with a high fill volume	The amount of powder should be verified and reduced to a standard defined by the manufacturer.
6		Different particle properties of powder	Granulating or milling of mixing powder can eliminate the particles that have different properties or are a different size than powder.
7		Incorrect filling of powder in V Tank	Horizontally layered filling of powder in the V tank can ensure quick mixing rather than vertically layered.
8	Vibrations in Machine	Loosing of parts can cause this problem	Monitoring the tightness of parts and tight those which get loose
9		If V Belt is worn, it can cause vibration	Check the V Belt and change it if required
10		A machine with no anti-vibration pads can create too much vibration	The placement of anti-vibration pads at the bottom of B type of mixer can reduce vibration.

11.What Are The Differences Between

A) V Type Mixer and Double Cone Mixer

Although, V type mixers and double conew mixers are type of tumbling mixer, there are significant differences in their design and working. Some of these disimilarities are detailed below:

• V type mixers are good for mixing medical and pharmaceutical powders because there is no risk of microbial contamination while mixing.
• Efficient mixing of free flowing dry solid powders and wet granules can be achieved by V mixers.

However, these mixers are not suited for mixing powders that vary in density and particle sizes. Since these powders can segregate after mixing.

13.What are the Special Designs of V types Mixers?

V Type Mixer with Intensifying Bar

Sometimes, V type mixers are customized with intensifying bar or agitator which is rotated at increased speed for bring about high shear mixing. This agitator is effective in boosting the mixing performance when dealing with cohesive powders.

Furthermore, these intensifying bars cause breakage of agglomerates and are employed during wet mixing of agglomerates. By using this intensifier homogenous mixing of fine as well as coarse powders can be achieved.

V Type Mixers with Asymmetrical Design

This type of V mixers is composed of two different length cylindrical shell giving it asymmetrical appearance. This design facilitates in movement of powders between two shells which decreases separation of powder particles and lowers the mixing time.

Asymmetry in design can also be achieved using baffles which are fixed in V type mixers. However, this design minimizes the access of operators to machine.
