Ginagamit ng Gravity Separator ang mga pagkakaiba sa density sa pagitan ng mga materyales upang makamit ang paghihiwalay. Malawakang ginagamit ito sa iba't ibang mga industriya, kabilang ang agrikultura, Pagmimina, pagproseso ng pagkain, at basura ng pag -recycle. Sa larangan ng e-waste recycling, Ang mga separator ng gravity ay gumaganap ng isang mahalagang papel sa pamamagitan ng mahusay na paghihiwalay ng mga metal mula sa mga hindi metal na materyales, sa gayon pagpapabuti ng mga rate ng pagbawi ng mapagkukunan at pagbabawas ng polusyon sa kapaligiran.
Ang prinsipyo ng pagtatrabaho ng gravity separator
Ang pangunahing prinsipyo ng isang gravity separator ay gagamitin gravity at Density ng materyal pagkakaiba para sa paghihiwalay. Kapag ang mga materyales ay pumasok sa separator, Ang mga ito ay pinoproseso ng mga puwersa tulad ng panginginig ng boses, Airflow, o daloy ng likido, nagiging sanhi ng mga particle ng iba't ibang mga density na naaayon nang naaayon. Ang mga particle ng Heavier ay tumira sa ilalim na layer, while lighter particles remain on the top layer. This layering effect enables efficient material separation.
The construction of a gravity separator is relatively simple and generally includes the following key components.
Application of Gravity Separator in E-Waste Recycling
E-waste contains a large amount of valuable metals such as gold, pilak, tanso, and rare metals, but also includes a lot of plastics, glass, and other non-metallic materials. Samakatuwid, efficient separation and recycling of e-basura are of great significance. Gravity separators play a key role in this process.
Separating Metals and Non-Metals
E-waste often contains a mix of various metals and non-metallic materials. Gravity separators can effectively separate high-density metals (such as copper, aluminyo, and gold) from low-density non-metals (such as plastics and glass). This process significantly increases the metal recovery rate and reduces the amount of non-metal waste to be processed.
Fine Separation
After the initial crushing and magnetic separation of e-waste, gravity separators can further perform fine separation. This step not only improves the purity of recovered metals but also reduces the complexity and cost of subsequent refining processes. Fine separation is particularly important for extracting rare metals, which typically have high economic value.
Circuit Board Recycling
Circuit boards are a very important part of e-waste, containing large amounts of precious metals and other valuable materials. Gravity separators can preliminarily separate the precious metal components in circuit boards, such as gold, pilak, and copper. These metals have high recovery value in the market, and effective separation can maximize resource utilization.
Cables and Wires
In the recycling process of cables and wires, gravity separators also play an important role. They can efficiently separate the metal cores from the external plastic sheathing. The recovered metal cores can be directly fed into the smelting process, while the external plastic can be further processed and reused.
SUNRISE has introduced an advanced gravity separation system for processing waste circuit boards. Through the efficient separation by gravity separators, the company successfully separates the metal components from the non-metallic substrates of the circuit boards. The separated metal components are further refined to recover a large amount of precious metals such as gold, pilak, and copper, significantly improving the company’s economic benefits. Meanwhile, the separated non-metallic substrates are further processed for the manufacture of new materials, realizing resource recycling.

Future Prospects
With the continuous update and replacement of electronic products, the amount of e-waste generated is also increasing. Efficient and environmentally friendly recycling technology is key to solving this problem. As an important separation device, gravity separators have broad application prospects in the field of e-waste recycling. In the future, with continuous technological advancements, the performance of gravity separators will further improve, and their applications will become more widespread and in-depth across various fields.
Gravity separators, by utilizing the density differences of materials, achieve an efficient and environmentally friendly separation process. In e-waste recycling, gravity separators not only improve the recovery rates of metals and non-metallic materials but also reduce environmental pollution, bringing significant economic and social benefits. With the continuous development of technology, the application prospects of gravity separators will become broader in the future, contributing more to the sustainable utilization of resources.
