E waste recycling plant setup cost
E-waste is also called e-waste, and the precious metal contained in it is tens or even hundreds of times that of natural mineral deposits, but the recycling cost is far lower than mining natural mineral deposits. Therefore, e-waste is often compared to an urban mine with abundant resources. Fully recycling e-waste not only has huge commercial value, but also promotes the sustainable development of society, economy and environment. TOMRA's photoelectric sorting equipment can recover various non-ferrous metals, stainless steel, wires, etc. from the broken materials of electronic waste.
E-waste waste circuit board recycling
SUNY GROUP can provide customers with a complete set of environmentally friendly crushing, recycling and screening equipment, as well as the overall design and construction plan of the system, as well as recycling and crushing of circuit boards, lithium batteries, cables and wires, and aluminum-plastic products. The aggregate produced by the crushing system can be recycled and reused in many fields. Using physical recycling method, supplemented by "three wastes" disposal measures, has the characteristics of green and low carbon, energy saving and environmental protection, no secondary pollution, etc., and takes into account economic and environmental benefits, not only realizes the utilization of valuable components, but also can reduce harmful components Harmless treatment, the mechanical physical method does not require the use of chemical reagents, and has lower energy consumption, which is an environmentally friendly method.
Previously, the methods of recycling electronic waste could only be processed by pyro-smelting and wet leaching. This time, SUNY GROUP proposed a new idea and produced circuit board recycling equipment, which uses dry physical Recycling technology can mechanically crush and recycle all kinds of waste circuit boards, computer boards, TV boards, aluminum-plastic boards, attached copper boards, printed circuit boards and processing waste, waste electrical appliances, etc. The metal recovery rate of circuit board recycling equipment is high , the purity of recovered metals is as high as 99%. No pollution to the air, no waste gas emission, compared with the chemical treatment method, the main advantage of the physical method is that the secondary pollution is small The comprehensive recycling rate of various components is high, realizing the recycling of electronic waste.
Circuit board recycling equipment is used to separate metal and non-metal in waste circuit boards, copper clad laminates, circuit boards and scraps, and reuse the copper and resin powder in them.
Circuit board recycling equipment, also known as waste circuit board crushing and sorting equipment, adopts high-voltage electrostatic separation technology to make the sorting more precise and efficient, and effectively control the loss of non-ferrous metals. The separation rate of the airflow separation equipment is as high as 97%.
E-waste precious metal extraction
Chips, north-south bridges, memory chips, integrated circuits, and plastic-encapsulated field effects that cannot be returned after dismantling are all collective materials with high gold and silver content in the components that meet the requirements of unified treatment. They can be roasted with ozone (ozone can completely destroy the components formed by combustion) Harmful fumes), the roasting slag is leached with solvent carrier, leached copper, lead and tin, and hydrochloric acid medium to leach gold, platinum and palladium, and extract gold, platinum and palladium. For SMD capacitors with high silver and palladium content, the acid method is used to independently extract silver and palladium. For gold-plated circuit boards and plug-ins, it is recommended to use a cyanide-free environmental protection gold stripper to quickly strip and extract gold. For silver and palladium-containing acoustic surfaces, metal-encapsulated triodes, and integrated circuits, use a special pin cutter to cut off the metal shell and punch out the chip, and then extract valuable metals according to the chip and integrated circuit scheme. For high-aluminum electrolytic capacitors, they are dry-rolled. Metal aluminum is smelted directly after being crushed. For Zener diodes, some varactor diodes, and other glass-encapsulated components and plastic-encapsulated light-emitting tubes, valuable metals are extracted after being crushed. Circuit boards are leached with organic acids and subjected to liquid electrolysis. Electrolytic copper is produced, and palladium-containing circuit boards (double-sided circuit boards basically contain palladium, and palladium is contained in the guide holes as copper-plated substrates) are then leached with acid, and then palladium is extracted and extracted. There are many equipments in the whole refining process, which will not be described in detail here.
E waste recycling plant cost
The recycling of electronic waste is mainly divided into two aspects, one is the crushing and sorting of waste circuit boards, resin powder and metal powder can be obtained, the other is precious metal refining and extraction of electronic components, gold and other precious metals can be obtained, as for the whole set of equipment The cost needs to be calculated according to the needs of customers. SUNY GROUP has rich experience and perfect technical equipment in the field of electronic waste recycling. If you need it, please contact us immediately.
