hand,the crushing degree of waste PCB is a basis,on the other hand,the percent recovery of metal materials is also very important.Sometimes, in order to achieve the recycling effect,we need to use several separators at the same time.

The essence of this method lies in the selective under-layer melting of powder material particles using electron beam in a vacuum environment (10-3 Pa), which is the most favorable environment for the machining of such highly reactive materials as titanium and titanium-based alloys.
