Size Reduction - General Polymer Services

Jet milling uses high-speed mechanical mills to collide pieces of the resin pellets into each other. This method can produce grains as fine as 1 to 10 microns. Jet milling can also work with oxidizers or highly explosive materials, as it does not introduce any volatile agents to aid with the grinding process.
