PARTICLE SIZE MESH TO MICRON CONVERSION & MILL APPLICATION CHART


Have a size reduction application, but not sure where to start? Crushing, grinding, pulverizing—there’s a lot of industry terminology out there, and it can be confusing.

To help guide your project toward the correct application, Williams Patent Crusher made this handy, downloadable particle size mesh to micron conversion and mill application chart.

When it comes to particle size reduction, this sizing chart can help give you a better understanding of particle sizing in both US and metric units and give you a general idea of what some of our size reduction equipment can achieve

 

What is Particle Size Reduction?

Put simply, particle size reduction is making big things smaller. For example, if you need large rocks crushed into gravel, that process is particle size reduction.

More officially, the definition of particle size reduction is the micronization and milling process to generate a more consistent particle size distribution. It’s an important step for engineering a myriad of materials, because it’s necessary to convert your large materials to smaller ones.

Let’s take a look at the specific types of particle size reduction, so you can get a clear idea of what size they actually are.

Crushing

Crushing is generally considered to reduce particles, like large rocks, to gravel-sized material. This translates to roughly 0 to 5 mesh.

Grinding

Grinding is generally considered reduction to table salt size, or about 5 to 25 mesh. 

Pulverizing

Pulverizing is generally considered to be reducing product to a fine powder. For instance, if you need coal, grain or other minerals to be in powder form, you would run them through a pulverizer or a roller mill. Pulverizing is typically defined as 25 mesh and beyond.

 

Williams Mill Types

We design and manufacture a variety of machines capable of handling the three main types of size reduction terms listed above. Our lineup of size reduction equipment include impact crushers, hammer mills, pulverizers, grinders and more. 

 

Hammer Mills

As you can see on the particle size conversion chart, hammer mills are usually used for crushing and in some cases, grinding.

Williams Patent Crusher’s hammer mills can crush and grind many different materials, such as limestone, glass, diatomaceous earth, coal, clay, shale, and a lot more.

Impact Dryer Mills

Impact Dryer Mills can perform a range of particle size reductions, including crushing, grinding, and pulverizing.

Impact Dryer Mills simultaneously grind dry and classify materials in one continuous, automated operation. There are many applications for these mills, including reducing clay to extreme fineness and grinding coal to proper fineness for burning in suspension.

Pulverizers & Roller Mills

Roller mills are used for grinding and pulverizing. Williams Patent Crusher’s roller mills will reduce materials like grain and ore to fine powders.
