E-waste recycling solutions
With the continuous use and upgrading of electronic products, more and more electronic waste needs to be recycled and reused. On the one hand, it can realize the reuse of resources, and on the other hand, it can also reduce the pollution of electronic waste to the environment. Among them, the more effective electronic waste recycling scheme is pure physical and mechanical crushing sorting and recycling.
The purpose of this scheme is to dissociate the metal in the waste circuit board from the organic matter as much as possible, so as to improve the sorting efficiency. The study found that when broken at 0.6mm, the metal can basically reach 100% dissociation. The recycling process of waste circuit boards has strong applicability/environmental protection. The physical method recycling process can effectively carry out mechanical crushing and recycling of various types of waste printed circuit boards, processing waste, and waste electrical appliances. The purity is as high as 96%. Secondly, the separated resin powder can also be reused.
Screening is to complete the separation by using the differences in chemical properties such as relative density, particle size distribution, electrical conductivity, magnetic conductivity and surface characteristics of raw materials. At this stage, a wide range of electrostatic separation and specific gravity separation techniques are used.
Advantages and Features:
1. The waste circuit board crushing and recycling production line is mainly used for the separation of metals and non-metals in waste circuit boards, copper clad laminates, circuit boards and scraps and other materials, with good comprehensive performance, recycling computer boards, computer board recycling, TV boards Recycling and other circuit board recycling have unique effects. It is also compatible with the recycling of various circuit boards containing capacitors.
2. Low noise, less labor, high automation procedures, improved efficiency, and smaller footprint. It is an ideal production line for recycling waste circuit boards to the present.
6. In order to prevent dust pollution during processing, a pulse dust removal device is added after the sorting process, which effectively solves the problem of dust pollution.
SUNY GROUP waste circuit board processing equipment rational sorting and production process: raw materials are shredded, roughly crushed, pulverized, air separation, vibration separation and sorting, environmental protection treatment and other processes, which can be recycled into copper-based metal mixtures. and non-metallic powder mixture; the dust and waste gas formed during the processing are collected in an orderly manner and uniformly subjected to dust removal and waste gas purification treatment, and are discharged to the air after the environmental protection standards are met. In addition, the collected primary waste circuit boards can be recycled by corresponding circuit dismantling machines, and the obtained electronic components and circuit board motherboards can be recycled and reused in the next step.
