What is a Pin Mill Grinder Used For?

Pin mill grinders are machines that are used to reduce and decrease the overall size of particles by breaking them down using a grinding mechanism.

Figure 1 – Sample image of what a pin mill grinder

Primarily, pin mill grinders utilize pins, which are then the ones used to break up, separate, and grind particles such as powders, fine powders, and other substances.

How Does a Pin Mill Work?

We know that a pin mill grinder works and functions by breaking the material down, but how does the process take place? What is the working principle of pin mill grinders?

Figure 2 – Sample image of how pin mill grinders work

The working principle or how pin mill grinders function is that the pins on the pin mill grinder reduces the size of bulk materials to about medium-to-small level fineness through impact.

Here’s a quick and easy summary of how pin mill grinders work and function.

1. The material is fed into the hopper or the feed inlet.
2. Then, the material will be drawn and fed to the pins that would be responsible for grinding them.
3. This will be continuous for the next few minutes or until the particles are fine enough to fit into the mesh.
4. When it achieves the size that it needs, it’ll then leave the machine by centrifugal force and will be collected through the outlet port.
5. Depending on the required size, the particles would be fed into the feed inlet again or until the right size is achieved.

That is the standard process of how pin mill grinders work and function.

What Are the Parts of a Pin Mill Grinder?

For you to know pin mill grinders better and more effectively, it is imperative to know and to determine the parts and the components, too.

Figure 3 – Different parts of a pin mill grinder

So, without further ado, here are the different parts of pin mill grinders.

Feed Inlet

This is the part or the component that’s responsible for introducing the material to the machine. Without the feed inlet, there’ll be no way to feed the particles that you want to reduce or grind.

Chute

A chute is a general term for an entryway or a pathway to which particles and substances can pass through to get from point A to point B.

The feed chute is the part or the component that delivers the materials and substances from the inlet to the discs that would proceed to grind it.

Stationary Disc

In a pin mill grinder, there are two (2) different types of discs: the stationary disc and the grinding rotor or the rotating disc.

The stationary disc, from its term alone, is a type of disc that’s non-locomotive. Meaning, it is the part that’s not stagnant all the way through.

Rotating Pins and Rotors

The rotating pins, rotors, and discs, on the other hand, are the parts that are locomotive or the ones that initialize the grinding and the reduction process.

Outlet Port

After it gets processed, it’ll then pass through the product discharge or the outlet port in order to be gathered and collected.

NOTE: Some pin mill grinders might have different parts and components. This will all depend on the manufacturer of the pin mill grinder, so, it is imperative to ask and inquire to the manufacturer about what the parts and components are.

Pin Mill vs. Hammer Mill

A lot of people aren’t aware of what the differences are between hammer mills and pin mills. So, in this particular category, let us try to unravel the differences between the two (2).

For you to be able to understand it better, here’s a table that would give you the differences between hammer mill and pin mill grinders.

What Are the Advantages of Using Pin Mill Grinders?

Figure 5 – You’ll find many benefits and advantages in using pin mill grinders

Using pin mill grinders can open a lot of different benefits and advantages. Some of which include:

You Don’t Need a Big Factory

Unlike other auxiliary equipment that are large and huge, pin mills won’t require a big floor space. As a matter of fact, a little floor space would be enough and sufficient to house and to make it work.

Can Reduce Particles Using Little Energy

In comparison to a hammer mill grinder, pin mill grinders can achieve the same, even better size reduction results in less energy.

This is also in line with the fact that it’s small, and therefore, it requires less energy.

You Can Use it Flexibly

And of course, pin mill grinders are versatile machines that you can absolutely bank and count on whatever business industry you’re in.

You can use it for a vast library of applications, you can use it to process slurry materials, moist materials, dry materials, and many more!

What Are the Disadvantages of Using Pin Mill Grinders?

While you may think pin mill grinders are all rainbows and butterflies, it’s actually not. There are a couple of cons and drawbacks in using them:

The Machine is Hard to Clean

The interior of pin mill grinders is filled with pins that are connected to the walls or the chamber. Therefore, you might find it inconvenient and requiring to clean after every time that you use it.

Susceptible to Wear and Tear

With pin mill grinders, friction is the name of the game. Therefore, you can expect it to be subject to wear and tear more frequently than other size reduction machines and equipment.

Usually Low Capacity

Since it’s usually small, you can’t expect it to be able to house large production processes. If you require large work volumes, what you have to do is to process them in batches.

What Business Industries Use Pin Mill Grinders?

Pin mill grinders are machines that are widely used in many different business sectors and industries. The most common business sectors and industries that utilize pin mill grinders include:

• Pharmaceutical Industry
• Food and Food Processing Industry
• Chemical and Biochemical Industry
• Construction and Structural Industry
• Mineral Industry
• And Many More!

How Many Pins Are in a Pin Mill Grinder?

The number of pins in a pin mill grinder is not constant. In fact, there’s actually no standard as to the volume of it.

There could be 15 to 20 pins on a small or a miniature pin mill grinder, there could be less, there could be more.

If you’re really interested to know about this, what you can do is to ask or inquire to your pin mill grinder manufacturer about it.
