Soaring ewaste affects the health of millions of children,

Effective and binding action is urgently required to protect the millions of children, adolescents and expectant mothers worldwide whose health is jeopardized by the informal processing of discarded electrical or electronic devices according to a new groundbreaking report from the World Health Organization: Children and Digital Dumpsites. How to Minimize Material Waste in Milling Operations,1: Recycling Metal Swarf. One of the first ways to minimize waste production from milling operations is to collect and recycle the metal chips/debris produced by the milling process. In most manufacturing centers, this is done via a third party. However, some companies have already begun using specialized equipment to recycle Hammer Mills / Shredders for EScrap ,The dual stage EDestroyer Hammer Mill offers superfine electronic scrap grinding, under 2MM, at very high production rates.
