Air Classifying Mill –– The Perfect FAQ Guide
At first glance, you would not expect air classifying mills to be a part of powder handling machines, but, they actually are.
In fact, they’re one of the most-used powder handling machines because of their primary function. Should you be unaware what air classifying mills are, then this guide is perfect for you!
Not only will you be learning what air classifying mills are, in fact, we will also educate and inform you in terms of how you can find the best and the highest quality of air classifying mills in the market today!
Before we get to that, do you really know what an air classifying mill is?
What is an Air Classifying Mill?
Figure 1 – Sample image of what an air classifying mill looks like
Air classifying mills or ACM machines, for short, are powder handling machines that are capable of producing fine particles.
Akin to other powder handling machines, air classifying mills are used for the production or the creation of fine particles through the high-speed grinding and spinning of the rotor disc with the grinding material attached to it.
Why is it Called An Air Classifying Mill?
This powder handling and powder processing machine is known as an air classifying mill because it separates and categorizes particles using a fair mix and combination of shape, density, size, and type with the aid and the help of rising air in a column within the machine.
The air drag is what’s pushing the particles into the disc in motion. So, if a particle is oversized, it’ll be thrown back into the rotating disc, while those that are already in the right size will become airborne.
And that is the reason why it’s called and labeled as an air classifying mill.
How Does an Air Classifier Mill Work?
The working principle of an air classifier mill is so simple and basic that it can be summarized into the one we’ll explain below.
Figure 3 – Image from a clip of how an air classifier mill works
The feed or the base particles are fed into the feed stock, which will then be transported to the rotor discs, in turn, the particles that have been reduced will come out of the product outlet.
To give you a more detailed version of it, here is the working principle of air classifying mills.
Step 1: Feed or Product Inlet
The particles go into the machine through the hopper, the feeder, or the feed inlet. It’s the hole that you’ll see either at the top of the machine or at the bottom of the machine.
It will then be transported into the classifier that has the grinding or the cutting media, which brings us to our next step, which is…
Step 2: Breaking Down of the Product
The product is broken down using the grinding media within the machine. The particles break and are divided into a few parts, but, the breaking process isn’t just limited to that.
Step 3: Further Fracturing of the Product
When the grinding media or the grinding material breaks down the products, some of the products are thrown to the lining or to the walls of the chamber, further breaking and fracturing them down.
Step 4: Filtering of Milled Product
Then, the classifier, that is continuously spinning and rotating, will then transport the materials that are small and broken enough down or up the chutes that are connected to the product discharge or the feed outlet.
Step 5: Fracturing of Oversized Particles
What happens to the particles that are still big and oversized? Well, thanks to the air that has been pulled into the machine, it’s thrown back again to the classifier, further breaking and fracturing them down.
Step 6: Removal of Dust
During this process, dust and debris from the action of breaking and fracturing are filtered and removed.
Some air classifying mill machines have filters that would then give you a wall that contains the dust and debris that has been filtered.
What Materials Are Separated in the Air Classifier Operation?
You’ll be able to find a wide range of materials that air classifying mills separate.
But, among the most common of which would include bulk solids through air classification. Looking back at the process of how air classifying mills work and function, the air would separate:
- Larger particles of bulk solids
- Ultrafine particles
- Dust
This is the primary reason why air classifying mills are commonly used in the agricultural and the chemical industry.
Apart from that, you’ll also be able to use ACM machines in other industries, so long that the industry requires the breaking down and separation of solids.
That brings us to our next question, which is…
What Can An Air Classifying Mill Work On?
Air classifying mills are versatile and flexible machines that you can use for a wide range of materials.
Figure 4 – Various powders that air classifying mills (ACMs) can process
Among the most common materials that you can use air classifying mills for include:
| Mineral Products | Food Materials | Chemical Materials |
| Talc | Food Additive | Dyestuff |
| Trona | Cocoa | Phosphates |
| Enzymes | Cane Sugar | PVC |
| Soft Limestone | Fiber | Synthetic Resin |
| Lithium Carbonate | Lactose | Chemical Salts |
NOTE: These are only some of the most common products you can get if you use air classifying mills. And, by looking at them, you’ll notice that most of them are powders.
What Are the Parts of an Air Classifying Mill?
Just like any other product, different air classifying mills have different parts and components. It’s not like all air classifying mills in the market would have everything similar.
Figure 5 – Different parts and components of a sample air classifying mill
As a matter of fact, different air classifying mill manufacturers and suppliers determine the parts and components differently.
But, to give you the common parts and components of air classifying mills, they include the following:
Feeder or Feed Inlet or Hopper
This part or component is the one that starts the process. The feed inlet, feeder, or hopper is the part where the products that are to be ground are placed.
Classifier Disc With Grinding Material
The classifier disc is the part that rotates, then classifies the particles according to their size, type, and density.
With the grinding material, it’s the overall component that separates the parts of bulk solids from one another.
NOTE: This is the component that makes the process possible.
Fan
The fan is the one that generates the airflow that would convey, mill, classify, and separate the products.
Airlocks or Air Intake
This is the controlling variable in an air classifying mill as this is the one that contains and controls the air within the entire machine.
Product Discharge or Feed Outlet
After the particles have been classified, the product discharge or the feed outlet is the component that’s used to collect the products that have been finished.
It’s where the particles that have been classified successfully goes out – it’s where products go out from the machine.
Do remember that not all air classifying mills have these at the exact terminologies. So, don’t be confused when you encounter a different term. We’ll give you a diagram or a graph of this so don’t worry.
Where Can You Purchase the Best Air Classifying Mills?
You’ll find many different manufacturers of these air classifying mills in the market. You can purchase from the U.S., some countries in Europe, as well as in Asia.
While you might think that ACM machines in Europe and in the U.S. are better, think again. A lot of businesses and companies there go to China and India for the manufacturing or the production of their air classifying mills.
But out of those two (2) countries, China is the one that’s rich with all different materials and sources.
