1.Working priciple. The processing is crushing --pulvering --separating , form whic the mixture of metal and non-metal is gained. Besides, separator combine with dust removl syesetm , due to different secifice gravity of materalis , non-metal such as dust , and grains which bears smaller graviry are taken away by dust removal sysetm, at the same time, the metal with lager gravity go into finished product recovery zone, thus the separation of metal and non-metal materials is achieved. 2.Advantage of pcb assembly 1).High recovery percent of metal , of which , the purity is up to 98%. 2).The price is only 1/5-1/3of that of the simaller product 3).The recovery rate of copper is about 3%-5% higher than other manufacturers of the sort 4).The unit consumption of energy to trest one ton of waste and unused pcb boards is only about 3/5 of that of domestic product alike 5).Easy operation, no polluction and noise, flexible for layout.
