Complete recycling unit for e waste
Before talking about e-waste recycling equipment, let’s talk about e-waste first. E-waste is very extensive. Before it becomes garbage, it can be said to include all aspects of our life and work. Just name a few products. They are all in use or are currently in use. In terms of life, there are mobile phones, TVs, washing machines, refrigerators, air conditioners, and even electric toys that children like. In terms of work, there are desktop computers, notebook computers, tablet computers, projectors, walkie-talkies, digital equipment, numerical control equipment, communication equipment, etc. I won’t give you examples of industrial grades, there are too many.
After talking about the generation of e-waste, let’s talk about the recycling and separation of e-waste by e-waste recycling equipment and the process of resource utilization. The recycling of e-waste is common to all of us on a daily basis. These are the first-line recycling practitioners who ride a tricycle through the streets and play on the loudspeaker to recycle old mobile phones and household appliances. After recycling, these people send them to several nearby recycling bins. , Some in the recycling bin are directly dismantled violently, and the circuit boards are classified together, and the plastic shells of these old appliances are smashed and classified into bags, which are convenient for transportation and do not take up space! Classification in the recycling bin After finishing, these e-waste will arrive at the home of these recycle bins, where they are basically all kinds of materials that have been sorted. After arriving here, we need our e-waste recycling equipment to process them! To contain all kinds of metal The circuit board of the material is further subdivided until there is only one kind of material in each material bag.
Next, let's talk about the crushing, separation and sorting of electronic waste recycling equipment. The whole line structure and process flow of circuit board recycling equipment: The circuit board processing and recycling production line is mainly composed of shredders, crushers, pulverizers, air flow specific gravity separators, high-voltage electrostatic separators and other auxiliary equipment.
Put the waste circuit boards into the first crusher, and use the roller crusher (first-stage crushing) to roughly crush the waste circuit boards, so that the circuit boards are broken into materials with a size of about 4 cm, and then enter the belt conveyor. The magnetic separator on the conveyor separates the iron in the material, and the remaining material will be sent to the secondary pulverizer by the conveyor for pulverization, making it a powdery mixture of metal and resin fiber powder; the pulverized material is in the Under the action of the negative pressure fan, it enters the No. 1 cyclone separator, and settles on the vibrating screen of the air flow separator through the external cyclone airflow of the cyclone separator. The light resin powder will enter the cyclone separator's internal cyclone airflow In the pulse dust collector. The materials entering the airflow separator are separated from metal powder and resin powder under the action of wind and vibration to obtain copper, resin powder and semi-finished products. The purity of the obtained copper can reach more than 85%, which can be sold directly.
The resin powder obtained therein will enter the No. 2 cyclone separator under the action of the fan, and the resin powder will settle into the screw conveyor along with the external swirling airflow, and then sent out, bagged and collected by the screw conveyor. The internal swirling airflow will bring light dust into the pulse dust collector. Under the filter of the dust bag, the dust settles to the bottom, and is sent out by the screw conveyor, bagged and collected. The filtered clean air is discharged from the top of the pulse dust collector. Among them, the semi-finished products obtained enter the electrostatic sorting machine through the closed screw conveyor, and are sorted again. The semi-finished products obtained by electrostatic sorting are basically materials that are not completely crushed and peeled off. The materials will enter through the screw conveyor. Go to the secondary pulverizer to pulverize again, and at the same time, electrostatic separation will get higher purity copper and resin products.
Waste circuit boards apply circuit board recycling equipment to the industrialized treatment of electronic waste. The circuit board recycling equipment crushing and separating device can crush and sort electronic waste such as waste circuit boards and copper clad laminates. For complex raw materials and different metal content The raw materials can be processed, the recovery rate is high, there is no waste water and smoke discharge, and it is not suitable for soaking in chemicals. It is green and environmentally friendly and sustainable! The prospect of using circuit board recycling equipment to recycle electronic waste is very broad!
