What is Yinda Air Classifier Mill ?

An air classifier mill is a type of powder handling and powder processing machine you want to use if you’re looking for finely reduced and deceased size on particles and materials.

 

air classifier mill

An example of what an air classifier mill machine looks like

For you to understand it easier and better, it’s a type of hybrid machine that incorporates a dynamic air classifier and a mechanical impact mill.

More often than not, air classifier mills are vertical types of machines that make use of internal air classifying wheels with independent and singular drives. Furthermore, these machines have materials that are sensitive to heat, which, in turn, allows complete control over the particle cut point.

 

What’s the Use of a Air Classifier Mill?

As we mentioned above, the idea behind classifier mills combine and mix the procedures of milling and grinding systems with particle size classifiers.

These classifier mills consistently and continuously circulate particles that are not at par with size requirements into the grinding and/or milling zone until the required size is achieved.

Due to the classifying action that transpires within the machine, you can be sure that the products that are from the air classifier mills would be exact and accurate to the size required, everything will be evenly distributed, and the physical properties of the materials will all be equal.

 

Where Are the Applications of Air Classifier Mills?

To further help you in understanding the principle of how air classifier mills work, here are the most typical and the most usual applications.

Pharmaceutical Industry

Air classifier mills have been popular in the pharmaceutical industry. How? – It’s because of their ability to fine grind and pulverize ingredients used in the pharmaceutical setting.

You can use air classifier mills to crush and grind active ingredients for pill and tablet making, as well as finely grinding ingredients before turning them into liquid.

Chemical Industry

Another of the most common industries that benefit from using air classifier mills is none other than the chemical industry.

We’re all aware that the chemical industry isn’t just filled with liquids and gas – you’ll have to consider the solid forms or powders of it, too.

More often than not, you can utilize air classifier mills for creating or producing of a ton of different ingredients in the chemical industry, namely:

  • Talc
  • Toner Powders
  • Dry Powders
  • Clay Powders
  • Coal Powders
  • Salt
  • Limestone
  • Dye Powders
  • And Many More!

Take note, though, that those aren’t everything. In fact, you can use air classifier mills to produce other substances by crushing and grinding them, too!

Food Industry

The food industry is among the most common industries and sectors that utilize air classifier mills.

Since most of the time, what makes up our food are made from grains, powders, and other smaller types of material, the food industry benefits a lot from using air classifier mills.

Part of the most common products that you can get from using air classifier mills in the food industry includes, but are not limited to:

  • Very Fine Flour
  • Rice
  • Sugar
  • Icing Sugar
  • Gluten
  • Powdered Sugar

  • Powdered Herbs and Spices
  • And Many More!

Pet food and animal feed industry

The industry of caring for domesticated animals have grown far to the extent of creating their food, as well as their other feeds are important.

For instance, finely grained and crushed dog food usually comes from big chunks of protein-based food. So, with air classifier mills, you’ll be bale to create uniform and finely grained and pulverized food that your pets can eat and consume.

Environmental Industry

Last but definitely not least in our list of industries that use air classifier mils would be the environmental industry.

From the term alone, the environmental industry is the sector or the industry that tackles the growth and the nurturing of the environment.

So, the creation of fertilizers, the uniformity of seeds, as well as other needed ingredients to nurture plants and/or the environment are the common products of air classifier mills in the environmental industry.

These are some of the most common industries and sectors that utilize air classifier mills. Do note, though, that these aren’t everything – in fact, there are many more businesses and industries in the world that needs it.

An example of what an ACM mill can produce 6

An example of what an air classifier mill can produce 

As a matter of fact, we can simply summarize it in a few easy steps.

 

 

Step 1: Preparation of the Machine and the Ingredients

The first step of operating air classifier mils is the preparation of the air classifier mil machine as well as the ingredients.

Preparation would include:

  • Checking of the machine’s parts and components
  • Testing and calibration of the machine functionality and operation
  • Loading of the materials to be milled and grinded
  • Activation of the machine

Once everything’s been prepared, it’s now the time to go to the next step, which is…

Step 2: Initial or First Stage Grinding

The initial or first stage or phase grinding involves the crushing or the grinding of the primary material. For instance, minerals into grains or finer particles, or food particles such as medium-sized chunks of protein into smaller-sized proteins for pet food.

Step 3: Classifying

When that’s done, all processed materials that are within the size requirement will go and pass through the rotors or the blades that perform the cutting.

For those that aren’t fit with the description or the size needed, they’ll be classified as materials that need to go through the operating machines again.

Step 4: Second Stage Grinding

Those that are to re-enter the rotors for the second time, or those that won’t accelerate into the output or the outward chute would have to be grinded and reduced once again.

In this stage or phase of the process, they’re now fully expected to be at par with the requirements. Otherwise, they’ll be sent out of the machine for assessment and for verification.

That’s the usual procedure on how you can properly operate air classifier mills. This is just a general structure or outline of how it works, of course, there are other air classifier mill units that have advanced features and functionalities.

 

What Are the Parts of an Air Classifier Mill?

Akin to the previous question, there could be many difference when it comes to the parts of air classifier mils, especially from different manufacturers.

  • Inlet From the Crusher or Other Grinding Machines
  • Air Inlet
  • Impact Rotor Drive Assembly
  • Classification and Grinding Zone
  • Hammers
  • Wheels of the Classifier
  • Rotor Discs
  • Air and Product Outlet

Without one (1) of these, you wouldn’t be able to call a machine or a device an air classifier mill. These are the most significant and relevant parts of air classifier mills.

Specifications You Need to Find For an Air Classifier Mill

Before purchasing an air classifier mill, you need to take note of the given specifications, first. Just like smartphones, tablets, laptops, and computers, you’d have to know the properties and the characteristics that they have before saying yes.

But, what do you need to look for in an air classifier mill? Here are some of the most important specifications to look for:

Product Size

This, of course, would dictate how big or small the products allowed in the air classifier mill would be.

There’ll be a ton of differences between many types of air classifier mills, but the general and the most common size of particles allowed would be 5 to 300 um.

Cutter Material

The cutter material would be the material inside your air classifier mill responsible for the size reduction of the particles and the materials.

The most common and customary type of material used for this would be hard alloys because of their sheer strength and their ability to cut through many different types and kinds of materials.

Power

The specification or the characteristic of power is relevant and significant to know if it’s going to be eligible for the machine you’ll house in your manufacturing plant.

Commonly, the power requirement of heavy-duty air classifier mills would be around 5 to 200 kW.

Maximum Classifier Rotational Speed

The air classifier’s speed pertains to the speed of the air coming into the machine. The faster the rotational speed of the classifier, the more air would come in and enter the machine to assist in the classification of particles and materials.

Maximum Cutter Rotational Speed

This particular specification is among the most important because it can dictate the rate of production, as well as the hastiness of the work.

Control System

Last but definitely not least would be the control system or how the system of the air classifier mill is going to be controlled.

There are many different variations of it, but the most common would be PLC or programmable logic controller.

These are the primary parts and components of air classifier mills. Do note that these are only general; not all air classifier mills are built and engineered in the same way.

What is an ACM Mill?

It’s a type of powder handling or powder processing machine that’s known to be the best and most ideal when it comes to producing uniform substances.

yinda acm mill

Figure 1 – A small-sized air classifier mill or ACM mill

Short for an air classifier mill, an ACM mill is one of the best and most-purchased powder processing and powder handling machine in the industry.

The primary purpose of an air classifier mill is to uniformly break materials down and separate them using direct physics through the help of centrifugal and gravitational force.

ACM Mill vs. Jet Mill

Jet mills, unlike ACM mills, incorporate a grinding area at the bottom of the machine. The classification zone can be seen at the top, which is where the materials fed will flow directly in.

These jet mills function by abruptly accelerating gas using a nozzle that is directed to a specific central focal point. Then, a series of nozzles are utilized to deliver the materials to the grinding zone for operation.

ACM mills or air classifier mills, on the other hand, employ the usage of two (2) stressing mechanisms that gradually reduce the size of the particles primarily by mechanical impact and secondarily by particle-to-particle attrition.

The machine uses air to transport the material into the mill, which is usually equipped with a rotating disc, reducing the size of the materials.

In summary, jet mills usually use gas and nozzles, while ACM mills use air to convey the materials to the mill to be prepared for size reduction or milling. Those are the primary differences between jet mills and ACM mills.

How Does an Air Classifier Work?

acm machine 2

Figure 3 – Image of what an air classifier is along with its independent parts and components

Air classifiers work by separating the materials using air, conveying materials that do not pass to the mill for them to be cut up, sliced, and finally ground.

The primary purpose of the “air classifier” in these mills is for the distinction and the identification of which particles and materials would already be fit to the requirement and the need of the process.

Do note, though, that we’re talking about the “air classifier,” which is just one (1) part or component of an air classifier mill or an ACM machine. We aren’t talking about the entire machine, just to be clear.

Therefore, this classifier, from the term alone, would be the component that would help and assist in the classification of materials. Thanks to this, particles and powders that are mixed can be well separated and categorized.

Here’s a video to help you better understand how air classifier mills work:

https://youtu.be/0TwJLS_Bars

Air Classifying Mill (ACM Mill) Working Principle

Air classifying mills or ACM mills operate on the working principle of impact grinding, along with particle-to-particle attrition.

Due to the fact that the materials are greatly broken down in the mills or chambers, it can then easily be concluded that the size reduction of the materials and particles are subjected through impact grinding.

To help you identify it even further, here’s a quick summary of how ACM mills work and function:

  1. You feed the powders and materials into the machine through the hopper or the feed inlet.
  2. Then, the powders would then be transported (via air) to the milling or grinding chambers.
  3. All particles and powders that are within the size specification would be transported to the discharge port or outlet. Those that are not within the specifics, however, would be conveyed back to the milling chamber for further processing.
  4. The dust particles that have accumulated would then be transported to the dust collector that is part of the machine.

This is the basic procedure of how ACM mills work and function!

What Sizes Can an ACM Mill Produce?

An example of what an ACM mill can produce 6

Figure 4 – An example of what an ACM mill can produce

The mesh sizes and dimensions that ACM mills can produce would depend entirely on how the manufacturing body created it.

To tell you honestly, it’ll be hard to determine the mesh sizes of what ACM mills can produce. But, on average, they’re able to produce somewhere about 10 to 150 µm (micrometers).

However, you’ll easily be able to find machines that are capable of producing up to 250 and 300 µm!

What Are the Applications of ACM Mills?

Akin to other types of powder processing and powder handling machines and equipment, ACM mills are flexible and versatile to the extent that you can use them for a wide range of business applications.

To give you the most common business sectors that use them, they include, bu are not limited to:

  1. Pharmaceutical Industry
  2. Chemical Industry
  3. Biochemical Industry
  4. Agricultural Industry
  5. Food Industry
  6. Animal Feeds Industry
  7. And Many More!

Did You Notice?

What do these business sectors and industries have in common? They all need materials and particles that are small and fine, yes.

So long as a business industry needs small, fine, even ultrafine particles, you can expect ACM mills to be needed in that particular sector.

What is the Most Preferable Milling Technique?

Split Type Air Classifier Machine

Figure 5 – An air classifier mill is the best milling procedure

Out of all the many different powder milling and powder processing machines in the market, ACM mills are known to be the most widely used milling technology.

They’re ideal not just because of the size of the products you’ll get when you use them, but also because of the keenness and the versatility of the process.

Among the benefits of using ACM mills include:

  • Higher throughput than regular and traditional sieving.
  • Can be used for high-efficiency precision
  • Easy to clean and low maintenance
  • Better, narrower, and finer product size distribution

NOTE: These aren’t all the benefits you can get from using an ACM mill. There are a lot more! Furthermore, you’ll be able to see and experience those once you get the chance to purchase an ACM mill!

Are there any limitations of Air Classifier Mill?

Air Classifier Mill can only produce fine powder. Air Classifier Mill cannot be used for coarse particles. Air Classifier Mills are also not suitable for milling sticky materials, such as putty and latex. Air Jet Mills have lower production capacity than other mills, such as hammer mills or impact mills.

Air Classifier Mills are also more expensive than other mills. Air Jet Mills can only be used for dry milling, and it is not suitable for wet milling. Air Classifier Mill has poor heat dissipation performance, so the temperature of its grinding chamber will rise during operation.

Air Classifier Mill vs Air Jet Mill: What’s the Difference?

Air Classifier Mill and Air Jet Mill are two types of jet mills. Air Classifier Mills are more common than Air Jet Mills. Air Classifier Mills have a wider range of applications than Air Jet Mills. Air Classifier Mills can be used for both wet milling and dry milling, while Air Jet Mills can only be used for dry milling. Air Jet Mills can produce finer powder than Air Classifier Mills, but their production capacity is lower. Air Jet Mill has more moving parts and higher requirements on equipment maintenance than Air Classifier Mill.

Air Classifier Mill vs Hammer Mill, Impact Mill or Ball Milling Machine: Which is Better Suitable for You?
