Ultra-Fine Particle Sizes with CPR’s Jet Milling Capabilities:

Jet milling is a cutting-edge micronization process that utilizes high-velocity compressed air or gas to achieve exceptionally fine particle sizes, often ranging from 50 microns down to less than 10 microns, and even smaller in some applications. This method relies on high-energy collisions between particles to grind them down, offering significant advantages over traditional mechanical milling.


How Jet Milling Process Works:

At CPR our state-of-the-art jet mills, materials are accelerated through precisely engineered nozzles into a grinding chamber. Within this chamber, particle size reduction occurs through high-speed, particle-on-particle impact. An integrated classifier wheel ensures that only particles reaching the desired size are drawn off, resulting in a product with a tight and consistent particle size distribution. The absence of moving parts in jet mills minimizes the risk of contamination and eliminates heat generation from friction.

Custom Particle Reduction (CPR) Jet Milling FAQ

  1. What is jet milling?

Jet milling, also known as micronizing, is an advanced process used to reduce the size of particles to an ultra-fine level. It uses high-velocity compressed air or gas to create high-energy collisions between particles, grinding them down. Unlike traditional milling methods, jet milling doesn’t use moving parts, which minimizes contamination and prevents heat generation.

  1. What particle sizes can be achieved with CPR’s jet milling?

CPR’s jet milling capabilities can achieve exceptionally fine particle sizes, typically ranging from 50 microns down to less than 10 microns. In some specific applications, even smaller sizes are possible.

  1. How does the jet milling process work at CPR?

Materials are fed into our state-of-the-art jet mills, where they are accelerated through specially designed nozzles into a grinding chamber. Inside the chamber, the particles collide with each other at high speeds, breaking down into smaller pieces. An integrated classifier wheel ensures that only particles that have reached the target size are collected, resulting in a consistent and narrow particle size distribution.

  1. When should I consider jet milling over other grinding methods?

Jet milling is the ideal solution when:

  • Ultra-fine particles are essential: Your product requires particle sizes in the single to low double-digit micron range.
  • Your material is heat-sensitive: The cool grinding action prevents thermal degradation.
  • High purity is required: The lack of moving parts reduces the risk of contamination, making it suitable for pharmaceutical, food-grade, and cosmetic materials.
  • You need a precise particle size distribution: Our equipment ensures a consistent and narrow size range.
  • You have difficult-to-grind materials: Jet milling is effective for hard, brittle, and crystalline substances.
  1. What industries does CPR serve with its jet milling services?
