Vibro Sifter manufacturer

I know you’d wish to screen material (separate into different grades by particle size).

Well, I have this guide for you.

Today, you’re going to learn how to choose the best vibro sifter machine for your material processing needs.

I will walk you through everything – from a basic definition, working principle, designs, parts and why you need it, just to mention a few.

And, later, I will recommend the best vibro sifter equipment you should buy.

Let’s dive right in.

What is a Vibro Sifter Machine?

I’ve just mentioned above that this is one of the machines that you require to process a wide range of pharmaceutical products.

Of course, each machine has specific roles to play because they are designeddifferently with varying properties.

And so if you’re in need of separation, scalping and grading during manufacturing, then this is the absolute equipment you require.

In other words, a vibro sifter machine refers to a vibratory sifting device which is designed to carry out separation, gradation and scalping functions.

It is a circular unitary rotating screen that you primarily use to separate and to grade different forms of materials in bulk.

For instance, you can use it to separate solid materials from solid, solid from the liquid as well as particle gradation.

It offers all these three primary functions for both wet and dry granulations in various applications.

Other than the pharmaceutical industry, the application of this machine is also typical in other sectors.

Some of these sectors include chemical, cement, and food processing industries among others.

Of essence is to understand that the role of a Vibro machine is to sift materials during processing.

Apparently, this implies that it mainly separates the mass composition of materials making it one of the most fundamental machines in production.

It thus implies that the design of this equipment is to help in achieving the right product quality by eliminating oversize granules.

In other instances, you’ll find that some people refer to this accessory as:

  • Safety screener
  • Vibro sieve
  • Vibrating sifter
  • Check screen or,
  • Control sieves.

All these many names ideally suggest the primary function of the machine which to separate and grade different sizes of particles.

Surprisingly, almost every pharmaceutical and food processing industry use this machine.

It could be at laboratory or manufacturing level depending on the actual need and use of this machine.

So that’s mainly the description of this machine.

But then, I’m sure you’d wish to know the major uses of this machine especially when it comes to material processing.

And that’s what we want to discuss in the next section;

Main Uses of Vibro Sifter in Material Processing

Ideally, the major uses of a vibro sieve tend to vary from one application to the other.

In fact, this is also dependent on the design and structures of the machine.

But still, it becomes easy to identify some of the important areas where the use of this particular equipment is common.

Therefore let’s get straight to the point and have a look at some of the main uses of this accessory;

· Sifting or Rebolting

Fundamentally, as the name suggests, this is one of the primary uses of this particular type of processing machine.

Incidentally, this merely means removal of lumps or growths that may form in a material as a result of extended storage.

What happens, in this case, is that the mesh opening is involved in the process that ultimately yields material that is relatively finer.

A practical example of sifting is regarding flour.

It happens when you remove strings, insect larvae, tags and insect fragments just after packaging or shipping before you release the product to the consumer.

So in a significant way this particular use is essential and necessary to enable the final product to attain the required properties.

· Scalping

This is the other important area where you can use a check screen.

It necessarily involves removal of lumps or a wide range of unnecessary foreign particles from a more refined material than its scalping screen.

Some of the unwanted foreign particles that you may get rid of using scalping may include twigs, tags, strings, and sticks among others.

Ordinarily, you’ll find that the size of the mesh or opening tends to be comparatively large than the product size.

It thus makes it possible for this process to easily take place at a current rate with high material quantity on a small screen area.

In the end, you’ll realize that the effectiveness of a separation process would also be somewhat high.

· Proof sifting

We also use a vibro sieve machine for proof sifting.

Apparently, this is the final verification of the quality of the product.

So in many industries, this equipment offers the final check on the product after the entire manufacturing process is over.

But you’ll realize that by the time you use this machine for proof sifting the product will already have been filtered earlier.

Also, you need to know that this might either be a scalping or grading task.

Thus it all depends on the type of installation.

· Screening or Grading

This is yet another essential use of a vibro sifter machine.

Screening or grading necessarily refers to the act of separating an ingredient by its actual size.

This is always evident when there is a reasonably close task which requires ideal separations of the material.

In some instances, this activity is referred to as bolting, sifting, sieving or sizing.

They actually mean the same thing in this context only that different people would prefer to use different terms.

Separating or sizing the materials using this machine can be fast or slow depending on many factors.

Some of such factors include the type of materials as well as its different properties.

The extent of processing the material is also a significant factor that determines the speed of screening or grading.

If throughput is comparatively low, it means that you would require less screen area.

So while using this machine, you also need to be aware of the necessary adjustments which you can make to it to attain high efficiency.

Don’t freak out!

We will look at some of these parameters later in this guide.

So keep on scrolling until the last section.

And so you’ll find out, a vibro sieve machine has several parts with all playing critical roles in achieving its functionality.

Well, speaking of parts and components, let us find out more regarding the same in this next section;

Parts of Vibro Sifter Equipment

Arguably, this is one of the most significant aspects which you have to know concerning a vibrating sifter.

Parts of a vibro sifter machine

Parts of a Vibro Sifter Machine

The truth is that once you grasp basic information about the components, it becomes easy to attain high efficiency and product quality.

Well, a vibro sifter machine consists of a wide range of parts and components.

And just like I stated earlier on, all these components have unique functions that they play in the overall operation.

But again, one thing that you have to understand is that the size of different components of this equipment also varies.

Of course, this is dependent generally on the design of the unit itself.

And so without taking much of your time let’s look at some of these parts and have a brief review of their roles;

i. Motor

This is the component that powers the machine so that it can run and carry out all the operations without unnecessary hitches.

Position of the motor in Vibro Sifter

Position of the motor on a Vibro Sifter

Understandably, the vibrating sifter uses electric power.

So it is the motor that is responsible for converting the electric power to the energy that drives the unit.

So when you see the continuous multi-plane vibratory motion, understand that it’s as a result of the power the electric motor is generating.

It’s vital since the vibratory motion increases the rate of ingredient particles passing through the various sieves.

Obviously, the size of motors for this machine varies also dependingon the size of the device and its design.

Its production capacity is also another element that determines the type of motor that such a machine runs on.

ii. Hopper Lid

You may at times refer to this particular component as the cover lid.

Mainly it covers the material that is processing from the upper section so that they do not fall whenever the machine is vibrating.

In most vibro sifter devices, the cover is always made of a metallic material.

Clearly, this helps in a great way precisely to avoid contamination and dusting.

It thus becomes possible for the lid to stay integral during processing since it has clamping rings that hold it together.

It also covers the mesh thus preventing it from coming into contact foreign objects that would damage it give that it’s somewhat fragile.

iii. Filter Screen

This component plays a significant role in making sure that it provides a smooth surface finish for the material during processing.

Different types of Vibro Sifter Sieves

Different types of Vibro Sifter Sieves

It is made using a wire mesh which has a relatively fine surface which is essential in sieving the materials and providesextremely fine particles.

Additionally, you can as well prevent any cases of leakage during material processing through its performance.

Filter screens also come in different sizes depending on the design of the particular machine.

iv. Wire Mesh Screen Ring

It primarily refers to a circular component where the wire mesh screen is attachedon.

The screen ring ordinarily contains glue that assists in bonding the mesh hence ideal for extending the lifespan of the mesh.

Also, the strong bonding helps the wire mesh to stay intact during material processing regardless of the vibration intensity of the unit.

v. Over-sized material outlet

In some cases, this component is known as an oversized material chute.

Ideally, it is a valve that releases the comparatively large material particles that remain after the sieving process is over.

Over sized material outlet

It is located on the upper section of the machine to make it possible for such particles to get out of the device quite easily.

vi. Screened material outlet

This is the opposite of the oversized material outlet.

It is a chute that lets out all the graded, screened or sized granule from the machine for further processing if there is the need.

Screened material outlet

This component is positioned at the lower section of the filter screen.

This is vital because it makes it easy for all the screened particles to collect and get out of the machine.

vii. Springs

The number of springs that a particular vibro sieve machine has is dependent on the specific applications it is tailored to perform.

These springs are generally the components that provide the machine with hydraulic movement.

They hold the upper section of the unit intact even as it vibrates to separate the materials.

In a broader perspective, the springs enable the machine to vibrate freely and act as a damper.

In this case, it prevents transmission of the vibration to get to the floor.

Springs in this machine also help in positioning the machine accordingly to provide the necessary efficiency during material processing.

viii. Control panel

Arguably this is one of the integral components of this particular type of sieving machine.

A control panel ordinarily consists of various buttons that send a signal to the equipment in regards to the specific action it should undertake.

I’m saying it is an integral part since it integrates technology which largely determines various aspects are revolving operation of the machine.

In some machines, the control panel features an LCD touchscreen display where you can operate the entire machine functions from.

Basically, these are the key parts and components of a vibro sifter equipment that you ought to know.

Incidentally, it is quite evidentthat this unit contains more than the mentioned components.

However, since we can’t discuss all of them here, you will undoubtedly understand them the moment you start working with this machine.

The most important thing is to at least know the basic components like the ones I’ve described here.

So that it becomes easier for you to relate and to understand how this machine works.

In that regard, I’m sure that the next question probably running through your mind is how this machine works.

And it’s for that reason that we want to look at the working principle of a vibro sifter machine;

How a Vibro Sifter Machine Works

Unquestionably, understanding the working principle of this device is one way of familiarizing with operating it.

You might know, but the truth is that once you have the basics, you’ll never find any difficulty in using this machine.

And so before we can even look at how this unit works, there is something important that you need to understand:

The working principle typically yields a process that is intended to accomplish more than the uses I mentioned earlier on.

Back to the main point now;

As you can see from the types of parts and components of this machine, it is pretty clear that it is relatively simple equipment.

But the truth of the matter is that in some instances, you might find it somewhat challenging to understand its working principle.

For that reason, let me simplify it for you to the best level possible for easier comprehension;

Working of Vibro sifter equipment

Working of Vibro Sifter Equipment

a) It starts when you pour the ingredients you intend to separate on a feeding hopper of the machine. At the same time, make sure that the base frame, cover and screen structure are all tightened with the clamping rings.

b) Now switch on the power from the electricity source. Thisapparently causes the motor to generate energy which instead enables it to vibrate as a result of off-balance weight assembly.

c) What follows is that the sieve begins to vibrate vigorously. Therefore, the granules you placed on the hopper then moves across the sieves and passes through the same depending on the required

d) The equipment features exit components which discharge the materials after the particles travel in a regulated pathway.

e) This happens right after successful separation of materials such that the larger ones are discharged in a separate container from the smaller ones.

f) Have it mind that at this point the size of desirable particles depend on the size of the permeable screens.

g) Once you’ve completed the entire process, you can again start all over. You just need to repeat the process all the time you need to separate your materials.

h) And at this point, depending on the construction of the machine, you can choose to use the vibrating sifter to do two major things;

i) Categorize the granules in the case of multi-deck and sift or scalp in the case of a single

And just imagine that’s all!

The working principle of vibrating sifter is that simple and straightforward.

And the best part:

Whenever you buy any model of this machine, you’ll find its user manual.

So it even becomes more straight forward to use this device.

But another thing you should never forget is shopping for a high quality vibro sifter machine that guarantees you efficiency in production.

To achieve this, you would also need to understand some specific designs and classification of this equipment to get a suitable one.

So let’s now look at some of these designs of vibro sieve machines;

Classification & Design of Vibro Sifter Machine

The production capacity that you expect is what determines the design, size and type of equipment which you’ll shop for.

Some of the fundamental aspects regarding the design include the following;

· Number of sieves

This machine comes in a single, double and triple layer depending on the specific application.

But the number of sieves your unit would require is also dependent on the extent of product separation it is designedfor.

· Specific application

You can use this machine in a wide range of applications.

You can as well use it in laboratory experiments and industrial processes.

And so what makes the difference in each case?


For small-scale applications you’d go for a relatively small-sized vibro sifter.

For industrial processes, you can go for somewhat larger options.

You’ll get all sizes in the market provided you conduct your search accordingly.

· General design

Essentially, the overall design of this type of machine depends on a particular manufacturer.

What I mean here is that every manufacturer comes up with their unique designs which they believe will give them an edge in the market.
