CRYOGENIC MILL

The solution for specific applications: cryogenic milling

In cryogenic milling, temperature-sensitive and lubricating products, including polymers, but also resins, foods, seeds and fine chemicals, are ground in our Cryogenic Mill.

The advantage of this method is that it prevents thermal damage and corresponding grinding losses.

We use innovative grinding systems with vortex screw cooler and liquid nitrogen cooling systems.

By using liquid nitrogen, the fracture behavior of elastic plastics can be completely changed. The cooling process causes a temperature drop below the glass transition temperature. This reduces the material’s ability to withstand high mechanical stresses due to its elastic properties. The result is cold embrittlement of the material – it breaks like glass.

With the grinding tool and the corresponding temperature, the shape, surface and size of the particles can be influenced

Advantages of this procedure:

• Higher output
• Preservation of essential oils and vitamins
• Prevents material sticking to the mill’s insides

Adding liquid nitrogen also contributes to fire and explosion prevention, microbial protection and protecting active ingredients.

Perfectly equipped for any application.
