Cryo-Grind Cryogenic Fine Grinding Technology for Rubber, Plastic and Pigment Size Reduction

Air Products Cryo-Grind technology performs the most efficient particle size reduction for all types of rubber, plastics and pigments. Cryo-Grind can undertake fine grinding of tough thermoplastic materials, polypropylene, nylon and rubber materials to particle sizes down to below 50 micron at controlled temperatures using liquid nitrogen.

Cryo-Grind for fine grinding plastics and pigments

Air Products Cryo-Grind systems perform three essential tasks in the efficient particle size reduction of all types of plastics and pigments.

   
Cryogenic Grinding - Grinding tough, thermoplastic materials at cryogenic temperatures means that plastics are brittle enough to be ground to very fine particles sizes.
   
Temperature Control - Cryo-Grind systems inject controlled amounts of liquid nitrogen to regulate the heat of the grinding mill and allow higher material throughputs at any time of year.
   
Inert Grinding - Organic materials have an increased risk of explosion when very fine particles combine. The use of nitrogen to make the atmosphere inert reduces the possibility of this occurance.
   
 

Benefits of Cryo-Grind for Plastics & Pigments
   
Smaller particles
Regular particle size
Efficient process
Effective temperature control
Inert atmosphere
Trial Facilities

Cryo-Grind for recycling rubber materials

Air Products Cryo-Grind systems enable rubber scrap materials to be ground into fine particles for reuse in compounding for new rubber and plastic products.
   
Benefits of Cryo-Grind for Rubber
   
Smaller rubber particles down to 100 micron
Regular particle size
Efficient process by introducing minimum nitrogen and maximum throughput
Improved surface Morphology
