Producing Fine Particles for Multiple Applications
Similar to dry milling, these processes can be easily scaled up, but they do not necessarily deliver the throughputs and ultra-fine particle distribution required by some processes. The plastics industry continues to explore cryogenic grinding as the demand for size reduction increases to particles sizes of less than 45 µm (325 mesh).
