With the continuous development of electronic and electrical industries, a variety of waste circuit boards produced in large quantities, endangering the environment. In this serious contrast is China's waste electronic products processing industry has not formed a scale, its recycling value has gradually attracted attention, environmental protection circuit board recycling equipment crushing separation of waste circuit board copper resources recovery and reuse of an efficient, environmentally friendly and economically viable process method, but also for the recycling of electronic waste to provide technical support. Circuit board recycling equipment processing technology and mechanical separation technology introduction.
1. Crushing technology: electronic waste components are mainly composed of various metals, reinforced resin plates and attached to its copper wire, components and plating on a variety of metals, etc., high hardness, toughness, need to use shear crushing process technology to break it, that is, with the shear effect of the crushing equipment can achieve a better dissociation effect.
2. Hydraulic drive technology, for the first two poles of the crushing shaft using hydraulic drive, in the cutting process will not occur overload plugging phenomenon, online detection, through the control valve can be bi-directional rotation.
3. Sorting technology: magnetic separation, density sorting, electrostatic sorting technology, through the joint sorting application, the different particle sizes, different stages of iron, non-ferrous copper and non-metal sorting out, so that can greatly improve the recovery rate.
4. Noise control technology: In order to reduce noise in the crushing equipment shield and interface to use special design, and the addition of shock-absorbing materials.
5. Dust removal airflow cooling control technology: In order to cool and remove dust, set up air jets in the drop side of the two-pole crushing equipment, and set up air outlets in the crushing cavity to loosen the material, so as to facilitate crushing, cooling and dust removal. External dust removal equipment can effectively collect the powder containing metal, while environmental protection.
Environmental protection circuit board recycling equipment production process using dry physical crushing and sorting, completely dry physical system; its advanced technology, the production process does not generate new problems, such as pollution of the environment, etc.. No waste gas and sewage generation, no noise pollution, the main core equipment using noise shielding room, workshop production noise to meet production standards, dust through the filtering system to meet emission standards, safety protection and other process design.
