Circuit boards or circuit boards as the core components of electronic and electrical equipment, is the foundation of the electronics industry. Waste circuit boards have attracted much attention in recent years because of their resourcefulness and hazardous nature. Dry circuit board recycling equipment to recover metals from waste circuit boards has become prevalent, so it is important to recover metals from circuit boards in an environmentally friendly and economical manner and dispose of the hazardous parts safely and properly. Circuit board recycling equipment such as crushing, sieving, gravity sorting, magnetic sorting or electrostatic sorting and other physical methods, crushing and metal enrichment of waste circuit boards is a necessary precursor to all recycling processes, compared to other methods are also more flexible and effective.
The new circuit board recycling equipment for recycling waste circuit boards, GreenJet environmental protection in the absorption of foreign advanced technology based on independent innovation environmental protection waste circuit board recycling equipment so that electronic waste into a renewable resource has become a reality. The complete set of equipment has three significant innovations:
1. the use of advanced physical recycling process, the whole set of process configuration is a domestic gap; the use of multi-layer combination of crushing and dissociation and ultra-micro classification technology, crushing and dissociation effect is ideal, high classification efficiency; the use of high-voltage electrostatic separation technology, high separation accuracy, to ensure that the metal recovery rate of 98%.
2. The special crushing and dissociation equipment for various kinds of used circuit boards is organically combined to achieve greater energy-saving effect in the production process, and achieve a high metal separation rate. Processing each ton of waste circuit board unit energy consumption is only about 1/2 of similar domestic products; sets of equipment can be processed up to 5 tons of high, the price is only 1/5 to 1/3 of similar foreign equipment, and copper recovery rate of 3% to 5% higher.
Circuit board recycling equipment can be widely used in all kinds of waste printed circuit boards, PCB processing waste, waste electrical appliances and other crushing treatment. At present, the product has been successfully used in many units of waste circuit board crushing, the user response is ideal, to solve the environmental pollution and waste of resources. Waste circuit board is a glass fiber reinforced resin and a variety of metal complexes, is a typical electronic waste, waste circuit board actually has a high recycling value. Circuit board recycling equipment from which the analysis of copper can be sent into the metal smelter as raw materials; other non-metallic powder such as glass fiber and resin can also be used as fiber reinforcing materials or fillers; its slag can also be used as raw materials for building materials.
