Description

1. Technical field

[0001] The patent of the present invention relates to a method for mechanically crushing and recycling waste electronic circuit boards at normal temperature, specifically a method for recycling and processing metal and waste metal materials in waste electronic circuit boards through mechanical crushing and electrostatic separation . 2. Background technology

[0002] Printed circuit boards (PCBs) are the foundation of the electronics industry. With the rapid development of the information industry, the production of printed circuit boards is increasing rapidly. The average annual growth rate of the world's printed circuit board industry is 8.7%, of which China's growth rate is 14.4%. By 1995, the total output value of my country's printed circuit boards had accounted for 50% of the world's total output value of printed circuit boards. At present, China has become a major producer and consumer of home appliances and electronic products. Since 2003, my coun...
