grinded in a ball mill. The fine powder/ash generated from the mill is sieved to separate chunks of metals. The left over ash from sieving is washed in the Ramganga River, where the ash flows and small quantities of copper are recovered. The CSE team saw many units with ball mills where brass work is also carried out.

According to the United National Environmental Programme, about 50 million tonnes of e-waste is generated annually across the world. The new approach is based on the idea of crushing e-waste into nanosize particles using a ball mill at very low temperature ranging from -50 to -150 degree C.

Ball Mill. Mills whose grinding medium consists of steel balls are called "ball mills". They are used in 35 mesh (425 micron) and finer grinding. Generally, they are used in the final stage of milling. In these mills, which produce a thinner product compared to rod mills, the ratio of neck to diameter varies between 1 and 1,5.
