Model Dry-Separation -PCB Board Recycling Machine
Electronic components will be moved by electronic components dismantle machine ,and then bared PCB board will be fed into the hammer mill to crush the material into powder, then goes to analyzer to sort most resin powder from copper mixed with less resin powder, resin powder outcomes from cyclone. dust and fineness resin powder will be blew to impulse dust catching system. Less resin powder and copper powder goes to vibration table. for suitable separating material goes to electrostatic separator machine. big size material not suitable to separate goes to hammer mill by soft pipe. copper recycling rate surpass 99.8%.Step 1: Electronic components dismantling
Usually, the first step of circuit board recycling is to separate the electronic components from the circuit boards by using PCB dismantling machine. Then you will get naked circuit mother boards, which will get further processing to get copper powder and resin powder
Step 2: PCB boards shredding and crushing
Circuit board shredder is the very first machine to size reduce circuit board. Its infeed opening should be big enough to process tons of circuit board at the same time. During shearing and crushing of 2 rotors, circuit boards are broken down into irregular pieces. For the first shredding machine, we choose the double shaft shredder. After circuit board shredding, the particles are around 60mm by 60mm. Next, the second crushing machine is a granulator, resulting in 20mm particles. Then the shredded material is collected in a mesh box and processed further.
Step 3: Separate the metal and non-metal powder
The shredded PCB will be separated by the air separator and the electrostatic separator. Our PCB recycling machine adopts dry type and physical crushing, separation and dedusting methods, which can keep no pollution to the environment. And the high pressure electrostatic separation combined with air separation process, which can purify approximately 99% metal powder.
