Today’ we will walk you through some of the most important and the most significant things to know about pin mills. In addition to that, we will also help and assist you in terms of finding the best pin mill supplier!

Without further ado, let’s dive straight into the guide!

What is a Pin Mill?

It’s a type of device or machine that can help, as well as aid and you in size reduction or comminuting materials.

Pin Mill Grinder

                                           An image of what a pin mill looks like

You can easily identify a pin mill because it would often have a hooper or an area where the materials can easily be collected.

Then, with a pipe or a downward opening – it’s what you can use to transport processed materials.

Why is it Called “Pin Mill?”

For you to be able to fully understand what a pin mill is we need to dissect the term itself.

pin mill (1)

It’s called pin mill because of the multiple pins that it has – it’s what it uses for grinding

While a pin mill is often also referred to as a disc mill, how is it dubbed and labeled as a pin mill?

Pin mill is a two-word term that contains the words “pin” and “mill.” The word pin is included because it utilizes a variety of pins for the process to be completed – it uses stationary pins and rotor pins.

And for the second (2nd) part, the word mill is because of the milling processes that it does. Milling or the general reduction process is what you use in order to grind, pound, or pulverize material so they can be transformed thin and granulated components.

How Does a Pin Mill Work?

You can think of a pin mill to work and function just like how a kitchen blender does. It utilizes pins installed at the center of the stator-rotor.

The product that needs to be ground is inserted and injected into the feed inlet, which goes down through the chute of the feed, and down to the pins that can process the material.

When the particular product is reduced, it then flows out to the product outlet or the end-process of the milling procedure.

You can purchase pin mills in either vertical or horizontal setting. You can choose based on where you’re more comfortable – or what you find more convenient.


Pin Mill vs. Hammer Mill

While yinda pin mills and hammer mills are used for the same purpose, they’re not a product that is 100% the same.

The pin and the hammer mills are two (2) of the most common types of machines you use in the processing industry and/or sector – how are they different?

Hammer mills are part of the oldest and the first technologies used by our ancestors in grinding and in pounding materials. The primary way hammer mills perform their operations is by reduction through the shear and impact of rotating hammers.

  • Consists of four (4) or more hammers that are together on a central shaft
  • Have different ways in reducing particles:
    • Chamber wall colliding with the particle
    • Repeated hammer impact
    • Impact of particle-to-particle

Pin mills, on the other hand, have pin breakers that are joined and attached to discs in the grinding chamber. Furthermore, pin mills function and work through impact and shearing methodologies.

The difference it has with hammer mills is that they’re speedier ,finer nd faster compared to using hammer mills.

What Are the Applications of a Pin Mill?

Thanks to their flexibility and their diversity, you can use a pin mill for a wide array of applications, including the food industry, the grain industry, animal feeds industry, chemicals industry, and many more!

Ideally, the purpose of pin mills is to fine size reduction, some of the most common ones include, but are not limited to:

  • Organics, food seasoning, sugar  and Other Food Products
  • Medicines and Pharmaceutical Products
  • Chemicals and Polymers
  • Gypsum
  • And Many More!

You will never be able to find a shortage of how you can use pin mills – they’ll be widespread in the market!

These pin mills are known for their different benefits, including the following:

1) Fully enclosed operation ensures hygienic final product and a clean workshop, with different types of dust collectors for a better optional dust removal.
2) Different types of knives ensure that it is suitable for different properties of materials.
3) The water cooling jacket ensures a continuous grinding effect without heating up the shaft and working chamber.
4) Use of different sieve sizes to adjust the fineness of the final particles.

The Composition of a Pin Mill

Different pin mill manufacturers might have innovated to produce more parts than the traditional ones.

However, there are certain parts and components that must never be left out that when they are, the pin mill wouldn’t be able to function properly.

Here are the main and the most important parts of a pin mill:

  • Feed Inlet – The part of the pin mill that you use to pour in the products for processing.
  • Bearing Assembly – It’s the component that’s responsible for the control and the assistance of the pins’ rotation and circular movement.
  • Chute – It’s the area within the pin mill that transports the products from the inlet to the processing area or the area where the pins are.
  • Stationary Pins and Stationary Discs – They’re the pins or the variables that do not move in any part of the procedure.
  • Grinding Rotors – Grinding rotors are the variables that make the grinding possible. They’re the ones responsible for the grinding procedure.
  • Feed Outlet or Product Discharge – This is the end part or where the processed material passes through, taking them outside of the pin mill. It will only exit the pin mill if it’s fine or processed enough.

Pin mills, on the other hand, are ideal for procedures that require size reduction of crystalline products or other goods that are in the same form.

What Are the Pros of Using Pin Mills?

Using pin mills offers a ton of benefits and advantages. As a matter of fact you’ll love them because of their overall flexibility and versatility.

pin mill

You can use pin mills for a wide range of industrial applications – whatever industry you are in

Some of its notable benefits and advantages include, but are not limited to:

Finer and Smaller Particle Size Results

Compared to hammer mills and ball mills, pin mills are the machines you can count on if you’re looking for results that have the finest and the smallest particle sizes.

Occupies Little Space

Unlike other auxiliary milling equipment, pin mills are smaller, and that means you’ll be able to store it in a little room or a little space.

Flexible and Versatile

You can use most, if not all pin mills for a wide array and variety of applications. You can use them to finely crush and granulate salt, sugar, medicines, minerals, chemicals, as well as other products that you need finely processed.

Those are three (3) of the primary benefits and advantages of using pin mills. But, what about it’s disadvantages?

What Are the Cons of Using Pin Mills?

You will get benefits in using pin mills, yes, but, it’s not all rainbows and butterflies.

In fact, there are a couple of cons and drawbacks to using them, too. Knowing what these are is important because it can be influential to your decision of whether using a pin mill would be good for you or not.

Friction Can Cause High Wear Instances

Just like any other milling machine, the friction of the pins can be the cause of the wearing out of the machine itself.

This is especially what the case is if you don’t pay attention to cleaning it every after usage.

They’re Not Easy-to-Clean

Going back to the first drawback, pin mills are machines and equipment that aren’t easy to clean. The parts and the components of a pin mill are too detailed and are highly focused – therefore, you might find it difficult to clean up.

As a matter of fact, you need to spend minutes to hours if you want to get it cleaned all the way through.

Capacity Might Not Be That Large

Given the fact that it doesn’t consume that space, you can also expect its capacity to be not that large. It will be, as a matter of fact, at the minimum.

So, you need to purchase a large-sized pin mill if you want large batches of grinding sessions. Purchasing multiple small pin mills would neither be practical nor economical.

Heat Generation Can Occur

Last but definitely not least of all the cons and drawbacks you can experience in using pin mills is that there could be heat generated to the products and even the raw materials being worked on.

This is due to the friction and the movement of all the materials that are present. These are the disadvantages and the drawbacks of using pin mills.

What are different parts of Pin Mill Machine?

Different pin mill manufacturers may have devised innovative methods for producing more pieces than the traditional ones. However, some parts and components must never be forgotten; else, the pin mill will not work correctly.

The following are the most essential and necessary parts of a pin mill:

1# Feed Inlet:

The feed Inlet is the part of the pin mill where you pour the things to be processed.

2# Bearing Assembly:

This component is responsible for managing and helping the pins’ rotation and circular movement.

3# Chute:

The segment of the pin mill that transports products from the inflow to the processing area or the area of the pin is known as the chute.

4# Mill Plate:

These are pins or variables that do not move at any stage during the procedure.

5# Grinding Rotors:

Grinding rotors are the components that make grinding possible. They are in charge of the grinding operation.

What are working principles of Pin Mill Machine?

Pin mills operate on the same principles as hammer mills but with a higher tip speed rotor-stator design with intermeshing pins that impact solids as they pass through.

Centrifugal forces propel the mill product to the perimeter, where it is collected or further processed. Micronized (less than 40 micrometres) materials with consistent product size are most likely to be produced using this milling technology.

Cooling the mill’s spinning discs is a great approach to get rid of the heat. Centrifugal forces propel the mill product to the perimeter, where it is collected or further processed.

What are the advantages of Pin Mill Machine?

  • It achieves smaller particle sizes than a hammer mill while consuming less energy.
  • Cryogenic conditions have enhanced heat evacuation from the mill in recent years.
  • The pin mill takes up very little space on the floor.
  • It can mill dry and brittle materials and has a wide range of uses.

What are the disadvantages of Pin Mill Machine?

  • Friction causes a lot of wear.
  • It is tough to clean the machine after it has been used.
  • Due to the small size reduction range, there is a tendency for a wide particle size dispersion to emerge.
  • Due to its size, it has a limited capacity.
  • Friction causes heat to be generated.

How Do I Choose a Pin Mill?

Choosing which pin mill to use for your business is one, if not the most important aspect of it.

Make sure that you know what you need before choosing a pin mill

Imagine purchasing the pin mill that isn’t capable of helping you with what you need – wouldn’t that be just a waste of money?

So, how do you identify which pin mill is the best pin mill based on your business needs and requirements?

Check the Arrangement and the Number of Pins

The count, number, and the overall arrangement of the pins in a pin mill are all essential in determining the finesse of the final products and particles.

In addition to that, this number can also help you in determining how narrow the distribution will be, as well as decreasing the production and the distribution of heat to the final parts and components.

How Easy Would it Be to Operate the Pin Mill?

Ease of operation should be at the top of your priority. As a matter of fact, all other things wouldn’t be too necessary because if the pin mill is easy-to-operate, you’ll never have a hard time on it.

Assess the Pin Mill Based on the Material You’ll Process

Check on the business sector or industry you’re in and see if the type of pin mill is within its specifications.

Are you working on crops, sugar, salt, and other types of food additives? Or are you working on chemical products?

These are some of the things that you can look up to before purchasing a pin mill.
