Feb 01, 2007018332Two major reasons for dust and fines are dull or improperly gapped knives. The sharper the knives, the more efficiently the granulator will chop the scrap, especially with soft, energy-absorbing materials. Sharper knives will produce a cleaner cut without tearing, resulting in greater energy efficiency, higher throughput, and fewer fines.
