particle size reduction for chemicals/rubber and plastics-2024欧洲杯官网

a cost effective way to achieve required particle sizes and production rates

air products’ polarfit® cryogenic grinding solutions can help you grind more effectively and efficiently, particularly for heat sensitive or tough-to-mill materials. our systems use liquid nitrogen to cool down a feed material prior to and/or during milling to either help prevent its melting or decomposition, and achieve embrittlement.

we have experience with many mill types and can provide or recommend a feed or conveying system. whether you have an existing cryogenic or ambient milling system that you need to upgrade, or plan to install a new system, we can help.

the fundamentals of cryogenic grinding

cryogenic grinding can help you cost-effectively achieve desired particle sizes or yield of particles in your target range; grind heat sensitive or tough-to-mill materials; as well as increase production, product quality and process safety. watch to learn about the fundamentals of cryogenic grinding, benefits and results of cryogenic grinding, safety considerations and precautions, and equipment requirements for cryogenics.

polarfit® cryogenic grinding solutions

watch how our polarfit® size reduction systems use the cooling power of liquid nitrogen to remove heat produced in the grinding process, allowing you to achieve higher yield of particles in your target range, more uniform particle size distribution, higher production rates, improved product quality and improved process safety due to the nitrogen inertness.

the major benefits of cryogenic grinding are:

  • higher yield of particles in your target range
  • more uniform particle size distribution
  • higher production rates
  • improved product quality
  • improved process safety due to the nitrogen inertness

from cryogenic services, industrial gas supply, to complete cryogenic systems, you can rely on air products experienced engineers to help you find the best solution for your process.

“what equipment do i need to set up a successful cryogenic milling operation?”

a cryogenic milling operation is very similar to a normal, ambient grinding operation. it can be set up in many different ways, but the basic components may include: the mill, a cryogenic conveyor, liquid nitrogen flow controls, a liquid nitrogen supply system, and then other supporting equipment common to normal, ambient grinding operations.
