What is circuit board recycling equipment? Circuit board recycling equipment is environmental protection equipment for processing and processing waste electronic waste, solid waste, waste circuit boards, waste copper clad laminates and other electronic waste recycling and processing, and complete equipment for waste circuit boards and circuit boards. Circuit board recycling equipment Material method environmental protection technology is the development trend of electronic waste disposal.

The process of SUNY GROUP environmental circuit board recycling equipment adopts dry physical crushing and sorting. Completely dry separation system; its technology is advanced, and there are no new problems in the production process, such as environmental pollution. No waste gas or sewage is produced, no noise pollution, the main core equipment adopts a noise shielding room, the production noise of the workshop meets the safety production standard, and the dust passes through the filter system to meet the environmental protection standard, safety protection and other technological design.

The first-level crusher of the circuit board recycling equipment uses a double-roll or three-roll electrostatic and shear crushing method to cut large pieces of discarded circuit boards, and the second-level crusher (fine crusher) is used for materials with a particle size of 20mm. For crushing, the technology used is a mixed crushing method of rotary shearing and hammering to perform secondary crushing of materials of a certain size. To ensure that the particle size after crushing meets the technological requirements, it is equipped with a variety of vibrating feeders suitable for uniform feeding of thin layers of different materials.

The density screening process of the circuit board recycling equipment: In the case of the same material size, the materials with different density in the mixture can be separated by the vibration and air separation process. The sorting is carried out in a closed cavity, so there is little environmental pollution, and the technology is mature, and the sorting effect is good.

Circuit board recycling equipment crushing process: The crusher crushes materials with a particle size of about 5mm into fine particles of about 2 mm, so that the multi-layer machine board can be separated from the pot, in order to effectively remove the colored in the waste circuit board Metal copper is sorted out to lay a good foundation for the early stage. The process is similar to that of the =-grade crusher, except that the screen is more dense. The number and durability of movable knives and static knives are better than those of secondary crushers; waste cables are disassembled and separated.

Circuit board recycling equipment sorting technology: using magnetic separation, density sorting, electrostatic sorting technology, through the application of combined sorting, different particle size, different stages of iron, non-ferrous metal copper and non-metal sorting out, so that Greatly improve the recycling rate; in order to reduce noise, special design should be adopted at the guard plate and interface of the crushing equipment, and damping materials should be installed; for cooling and dust removal, air jets are set in the blanking side of the two-pole crushing equipment, and the crushing The cavity is equipped with an air outlet to loosen the material to facilitate crushing, cooling and dust removal. The addition of dust removal equipment can effectively collect the powder of poultry precious metals and is environmentally friendly.
