The principle of separation of metal and plastic in circuit board recycling equipment

Pubdate: 2023-12-29

Many people may not understand the principle of separation of metal and plastic by circuit board recycling equipment. In order to answer your questions, today we will share some relevant knowledge, hoping to help you better understand the use of circuit board recycling equipment. and value.

Waste circuit board recycling equipment and its recycling process:

A set of processes that dismantle and separate scrap circuit boards into metals and non-metals. For circuit boards with electronic components, remove the components after desoldering and disassembly (the components are classified and processed separately). The circuit board completes the dissociation of metals and non-metals through coarse crushing, iron removal, and fine crushing, forming a mixture of metals and non-metals, which enters the air flow specific gravity screen to extract most of the metals. The circuit board fiber powder screened out by air flow specific gravity contains a small amount of fine metals (about 2-5% content), and then enters the electrostatic separator to extract the remaining fine metals to achieve a high metal recovery rate.

Composition and working principle of circuit board recycling equipment

The circuit board recycling and processing production line is composed of the following equipment, crusher, special crusher, classifier, silo, dust collector, high-voltage electrostatic sorting equipment, etc. The waste circuit boards are crushed, dusted and then to high-voltage electrostatic sorting equipment. Materials are separated by conductive and non-conductive characteristics. The high-voltage electrostatic sorting equipment has three outlets at the front and rear. The front outlet is metal, the rear outlet is mixture, and the outlet on the left is PCB material. Circuit board recycling equipment uses the different physical properties of materials to separate metals from non-metals so that materials can be placed in their proper places. The recycling of effective materials helps society increase resources. Environmentally friendly circuit board recycling equipment enables the sustainable utilization of rare resources, including precious metals, copper and other high-content metals

The circuit board recycling equipment combines excellent domestic and foreign technologies to mechanically crush and recycle all types of waste circuit boards, computer boards, TV boards, aluminum-plastic panels, attached copper boards, waste electrical appliances, etc., and physically separate them. The metal recovery rate is high, and the recycled metal The purity is as high as 98% (under experimental environment). And it has the advantages of high purity, high separation rate, low energy consumption, excellent price, good recovery rate, good comprehensive performance, environmental protection and no noise.
