Circuit board crushing, sorting and recycling equipment
Circuit board crushing, sorting and recycling equipment is an important tool for processing waste circuit boards and separating metals from non-metals. This type of equipment combines advanced physical and chemical recycling processes, and has the characteristics of high efficiency, environmental protection, and high resource utilization. The following is a detailed introduction to circuit board crushing, sorting and recycling equipment:
1. Equipment composition
Circuit board crushing, sorting and recycling equipment mainly consists of the following parts:
Crusher: Preliminary crushing of waste circuit boards to make them into smaller particles or powder.
Pulverizer: Further refine the crushed circuit boards to increase the degree of dissociation between metals and non-metals.
Separator: Uses high-voltage electrostatic separation, airflow sorting and other technologies to effectively separate metals (such as copper, aluminum, etc.) from non-metals (such as resin, glass fiber, etc.).
Dust collector: Used to collect and process dust in the production process to prevent environmental pollution.
Other auxiliary equipment: such as feeders, silos, air pressure conveyors, air locks, storage rooms, etc., to ensure the smooth operation of the entire production line.
II. Working Principle
The working principle of circuit board crushing and sorting recycling equipment is mainly based on the difference in material conductivity and relative density. In a high-voltage electrostatic field or a composite electrostatic field, the materials are separated by the action of power engineering and mechanical equipment. The specific process is as follows:
Crushing and pulverization: The waste circuit boards are first processed by a crusher and a pulverizer to form a mixture of metal and resin fiber powder.
Separation: After the mixture enters the separator, it is separated according to the conductivity and relative density of the material using high-voltage electrostatic separation technology or airflow sorting technology. Metals with good conductivity (such as copper) will be attracted by static electricity and separated, while non-metals will remain on the other side.
Collection and treatment: The separated metals and non-metals are collected and sent to subsequent treatment links. At the same time, the dust collector collects and treats dust in the production process.
III. Equipment Features
High Efficiency: Using advanced physical and chemical recycling processes, the metal recovery rate is high and the purity can reach more than 98%.
Environmental Protection: Equipped with environmental protection equipment such as dust collectors, dust pollution and secondary pollution are effectively prevented.
Energy Saving: Achieve greater energy saving effects during the production process, and low unit energy consumption.
Flexibility: The equipment is flexible in placement and can be configured and adjusted according to actual production needs.
Compatibility: It has good treatment effects on various types of waste circuit boards, computer boards, TV boards, etc.
IV. Application Fields
Circuit board crushing, sorting and recycling equipment is widely used in the fields of electronic waste treatment, resource recycling and reuse. Through the treatment of this equipment, the metals in the waste circuit boards are effectively recovered, and the non-metals can be used to produce floor tiles, decorative materials, insulation materials and other composite materials or plates.
Circuit board crushing, sorting and recycling equipment is an efficient, environmentally friendly and energy-saving waste circuit board processing equipment. It is of great significance to promote resource recycling and reduce environmental pollution.
