Circuit board recycling equipment workflow is what

Summary: circuit board recycling equipment consists of crushing system and high-voltage electrostatic separation system, the equipment can be all kinds of waste circuit boards, computer boards, TV boards, aluminum-plastic boards, copper boards, printed circuit boards and processing waste, waste electrical equipment, such as mechanical crushing and recycling treatment. So, what is the workflow of circuit board recycling equipment? What are the characteristics of circuit board recycling equipment? The next step is to come together with the editor to understand it. Circuit board recycling equipment is the end-of-life circuit board dismantling decomposition separation into metal and non-metal a set of process flow. Circuit boards with electronic components are de-tinned and disassembled to remove components (components are categorized and then processed separately). Circuit boards through the coarse crushing, iron removal, fine crushing to complete the dissociation of metals and non-metals, the formation of a mixture of metals and non-metals, into the air flow specific gravity screen, most of the metal extracted. The circuit board fiber powder from the air-flow specific gravity screen contains a small amount of fine metal (about 2-5% content), and then into the electrostatic separator to extract the remaining fine metal, to achieve the maximum metal recovery rate.

What is the workflow of circuit board recycling equipment

1, recovery of various types of chips, capacitors, tubes

(1) heating: the circuit board is placed on a coal stove and heated to soften;

(2) extraction: extraction of a variety of chips, as well as capacitors, tubes, and other electronic components;

(3) classification: a variety of chips and electronic components are Classification;

2, extraction of solder.

The circuit board that has been removed from various chips and electronic components is placed on the stove separated by an iron plate or pan to continue heating. The tin and other solder on it will melt and drip on the pan or iron plate, which will be collected and sold after melting.

3, extraction of gold

(1) acid bath: circuit boards on a variety of things have been removed, such as circuit boards on the gold-plated part, it will be put into a strong acid solution;

(2) Reduction: the gold in the strong acid is reduced to a low purity of gold;

(3) heating and refining: low purity of the gold to be further purified to make the purity of higher Some of the gold;

4, extraction of copper.

Collection of a variety of copper-containing circuit boards have been removed in addition to all the appendages, copper extraction.

Circuit board recycling equipment features

1, the use of advanced mechanical crushing, high-voltage electrostatic separation of new technology. After crushing and dissociation, the separation of metallic and non-metallic materials is carried out with high purity;

2, the key technology is to organically combine the special crushing and dissociation equipment for various waste circuit boards to achieve greater energy saving in the production process and realize a high metal separation rate;

3, the unit energy consumption for processing each ton of waste circuit boards is only about 1/2 of the similar products in China; The hourly processing capacity of the complete set of equipment is up to 1 ton.

4, its selling price is only 1/5-2/3 of similar equipment at home and abroad, and copper recovery rate is 3% -5% higher than similar manufacturers.

5, the comprehensive performance is good, on the computer board, computer boards, TV boards and other line control boards have a unique effect, but also on the capacitor-containing parts of a variety of circuit boards recycling the same compatibility.

6, this production line is the upgrading of wind-selective products, than wind-selective power consumption is reduced, and no noise, less artificial automation procedures, high efficiency, while occupying a smaller area, is the waste electrical (line) circuit board recycling to the current most ideal production line.

7, less labor, no pollution, no noise, equipment placement with flexibility.

7, less labor, no pollution, no noise, equipment placement has the flexibility.
