DP Pulverizers® Cryogenic Grinding Mills

Advanced Low-Temperature Grinding Systems for Heat-Sensitive Materials

Cryogenic Milling Solutions by DP Pulveriser UK

Many materials become difficult—or even impossible—to grind efficiently at ambient temperatures. Products containing oils, fats, waxes, elastomers, plastics, polymers, adhesives, and certain pharmaceutical compounds can soften, smear, agglomerate, or degrade during conventional milling processes.

Cryogenic milling solves these challenges by cooling materials to extremely low temperatures prior to and during size reduction, allowing products to become brittle and easier to grind while preserving their physical and chemical properties.

At DP Pulveriser UK, we design and supply advanced cryogenic milling systems engineered for precision particle size reduction of heat-sensitive materials across the food, pharmaceutical, nutraceutical, chemical, polymer, battery, and advanced materials industries throughout the United Kingdom and Europe.

Trusted by industry leaders worldwide.

What Is Cryogenic Milling?

Cryogenic milling is a particle size reduction process that utilises extremely low temperatures—typically generated by liquid nitrogen—to cool materials before and during grinding.

By reducing product temperatures well below ambient conditions, many materials that are difficult to process become brittle and fracture more efficiently during milling.

Cryogenic grinding offers significant advantages when processing:

  • Plastics
  • Rubber
  • Elastomers
  • Adhesives
  • Waxes
  • Food ingredients
  • Spices
  • Pharmaceutical compounds
  • Battery materials
  • Specialty chemicals

The result is improved grinding efficiency, finer particle sizes, enhanced product quality, and reduced thermal degradation.

How Does a Cryogenic Mill Work?

The process begins by introducing material into a cooling zone where liquid nitrogen rapidly lowers the product temperature.

Once the desired temperature is achieved:

  1. Material enters the grinding chamber.
  2. The brittle product is subjected to impact, shear, or attrition forces.
  3. Particle size reduction occurs efficiently with minimal heat generation.
  4. Fine particles are discharged and collected.
  5. Nitrogen gas is safely exhausted or recovered depending on system configuration.

The combination of low temperatures and high-energy grinding enables particle sizes that may be impossible to achieve through conventional milling methods.

Why Use Cryogenic Milling?

Process Heat-Sensitive Materials

Many products lose quality when exposed to heat generated during conventional grinding.

Cryogenic milling preserves:

  • Flavours
  • Aromas
  • Active ingredients
  • Nutritional value
  • Functional properties
  • Chemical stability

Produce Finer Particle Sizes

Cooling materials below their brittle point often enables significantly finer particle size reduction.

This can improve:

  • Dissolution rates
  • Product performance
  • Surface area
  • Blending efficiency
  • Product uniformity

Prevent Product Smearing

Materials such as plastics, waxes, rubber, and oily products often smear during ambient-temperature grinding.

Cryogenic processing prevents:

  • Product build-up
  • Screen blockage
  • Agglomeration
  • Melting
  • Material degradation

Improve Production Efficiency

By improving brittleness and grindability, cryogenic milling often increases throughput while reducing energy consumption.
