E Waste Recycling Plant

1、Equipment Introduction

The waste circuit board crushing and recycling production line is mainly used to separate metals and non-metals in materials such as waste circuit boards, copper-clad laminates, circuit boards and scraps.

The successful development of this machine not only improves the quality of recovered copper, but also prevents secondary pollution.

This production line uses secondary crushing for recycling waste circuit boards, turning them into a mixture of metal and resin fiber powder;

The metal is then separated from the resin through air and electrostatic sorting.

In order to prevent dust pollution during processing, a pulse dust removal device is added after the air flow separation process, which effectively solves the dust pollution problem.

2、Product Introduction

The waste board crushing and recycling production line is mainly used to separate metals and non-metals in waste circuit boards, copper-clad laminates, circuit boards and scrap materials.

1. It has good comprehensive performance and has unique effects on computer board recycling, computer board recycling, TV board recycling and other circuit control board recycling. It is also compatible with the recycling of various circuit boards containing capacitor components.

2. This production line is an upgraded product based on the old equipment, with further reduced power consumption, no noise, less manual labor, high automation procedures, improved efficiency, and a small footprint.

3. The complete set of equipment adopts a new type of dust collector, and the three-in-one dust removal (cyclone dust removal + electrostatic dust removal + static dust removal) does not emit waste gas to the air.

4. The equipment has a clean appearance and no dust bag, which replaces the problems that traditional dust collectors cannot solve due to dust and odor.

5. In order to prevent dust pollution during processing, a pulse dust removal device is added after the air flow separation process, which effectively solves the problem of dust pollution.

3、Equipment Characteristics

1. A circuit board crusher is used for mechanical crushing and new high-voltage electrostatic separation processes. After dismantling, crushing and dissociation, metallic objects and non-metallic objects are sorted with high purity. The separation purity of the complete circuit board equipment reaches over 99.5%.

2. The key technology is to organically combine special crushing and dissociation equipment for various waste circuit boards.

It achieves greater energy saving effects during the production process and achieves a high metal separation rate.

3. The energy consumption per ton of waste circuit boards processed by circuit board equipment is only about 3/5 of that of similar domestic products;

4. The selling price of circuit board equipment is only 1/5-1/3 of similar equipment at home and abroad, and the copper recovery rate is 3%-5% higher than that of similar manufacturers.

5. It has good comprehensive performance and has unique effects on computer boards, computer boards, TV boards and other circuit control boards. It is also compatible with the recycling of various circuit boards containing capacitor components.

6. Less labor and no noise, and the placement of circuit board equipment is flexible.

6、Process Flow Description

1. Shredder: Shred the bare board to 2-3 cm.

2. Circuit board crusher: crush the crushed circuit boards to about 20 mesh.

3. Analytical machine: The crushed materials are winnowed to separate the resin, copper, dust and fibers. The dust and fibers are sucked into the collector by the induced draft fan, and the resin and copper enter the classification screen.

4. Collector: collects dust and fibers, and discharges the collected fibers.

5. Pulse purifier: collects dust and ultrafine fibers generated during the crushing process.

6. Grading screen: Screen the resin and copper. The unseparated resin and copper are returned to the host machine for crushing. The separated resin and copper enter the specific gravity separator for sorting.

7. Specific gravity sorting: The resin powder and copper are sorted by specific gravity. Since the weight of copper is greater than the weight of resin, copper will be sorted to one side and resin to the other side. In this way, metals and non-metals are separated. This is currently a better technology in China, which can achieve a metal sorting effect of more than 99%.

8. High-voltage electrostatic separation: The tailings that have passed through the specific gravity separator are then subjected to high-voltage electrostatic separation to separate the small copper powder and resin contained in the tailings.

The principle is: adjust the input power supply to a high voltage of 100,000 volts through a transformer to form a high-voltage magnetic field, which has an adsorption effect on conductive metals, thus achieving the separation of metals and non-metals.
