SUNY GROUP circuit board recycling equipment crushing and sorting circuit board process introduction:

ZY-BRB Circuit Board Recycling Line

1. SUNY GROUP environmental protection circuit board recycling equipment adopts shredding + multi-stage crushing + powder classifier + sorting vibration + cyclone separator + bag filter (exhaust gas purification equipment).

2. First remove the large components on the circuit board, and manually feed the circuit board to the belt conveyor line.

3. After the first-level shredding, the materials are transported to the second-level crusher through the belt for crushing, and the crushed materials are transported to the material storage room through the belt

4. The materials are uniformly transported to the three-stage pulverization through the sorting vibration, and the material particles reaching s2mm through the three-stage pulverization are then passed through the powder classifier for the material specific gravity separation, and the lighter resin and heavier resin are separated. The copper powder and copper powder are then separated by a vibrating separator for material particle separation.

5. After sorting, the copper powder that reaches 50.2-0.5m is sent out to the workers for packing, and the copper powder larger than 0.5m is returned to the three-stage crusher for crushing.

6. The sorting method of SUNY GROUP environmental protection circuit board recycling equipment is winnowing vibration or static electricity. After finely crushing, the coarse material has a particle size of 0.2-0.5mm, non-metallic fine powder 80-120 mesh, equipment working noise ≤ 85 decibels, metal recovery rate ( Weight ratio) 95-98%, loss rate ≤ 2%, metal separation rate ≥ 90%, metal content (weight) in metal powder ≥ 80% (the raw material contains copper ≥ 20%.

7. Increase the negative pressure at the discharge port of each main equipment and the crushing chamber to pull the dust to the cyclone for dust removal, and discharge it after reaching the standard after the pulse dust removal, cloth bag and exhaust gas purification equipment.

8. The dust collector layout of SUNY GROUP environmental protection circuit board recycling equipment is sorted and set with bag pulse dust collectors, and two sets of bag dust collectors are installed at dust points such as tearing machines, crushers, shredders and conveyors. The exhaust gas is filtered and discharged to the standard.

SUNY GROUP environmental protection circuit board recycling equipment electronic waste intelligent crushing system achieves automatic disassembly and separation of electronic waste through intelligent processes such as crushing, separation, sorting, and dust removal. It not only achieves effective crushing, but also greatly improves the efficiency of subsequent resource reuse. It has become a widely acclaimed electronic waste shredding solution on the market.
