Self-Aspirated Mechanical Flotation Cells

Self-Aspirated Mechanical Flotation Cells are core mineral processing equipment of Qingdao EPIC Mining Equipment Co., Ltd., specifically designed for the separation of non-ferrous metals, ferrous metals, and non-metallic minerals. Without the need for external blowers, these cells can self-aspirate air and slurry, making them suitable for various mineral processing scenarios and serving as key equipment for efficient separation in mining operations.

1. What is Self-Aspirated Mechanical Flotation Cells?

This product This product are a type of mechanical flotation equipment that utilizes the vacuum generated by rotor rotation to aspirate air and slurry without relying on external blowers, and they are widely applied in mineral separation processes. As one of the core products of EPIC Mining Equipment, this category of equipment is compatible with a wide range of minerals, including non-ferrous metals such as copper, lead-zinc, gold, and molybdenum, ferrous metals like iron ore, and non-metallic minerals. Its core advantages lie in its compact structure, small footprint, and elimination of the need for additional aeration equipment, which effectively reduces infrastructure and operational costs. To address high-hardness slurry scenarios, We has also launched a derivative model—the Wear Resistant Self-Aspirating Mechanical Flotation Cell—with upgraded wear-resistant materials to further extend the equipment's service life.

2. How it works?

The working process of EPIC Self-Aspirated Mechanical Flotation Cells is clear and efficient, requiring no external auxiliary air supply equipment throughout. First, slurry enters the cell tank through the feed pipe. Then, the high-speed rotation of the rotor generates centrifugal force, forming a negative pressure zone. Air is automatically sucked in via the air intake pipe and fully mixed with the slurry. Under strong agitation, the impeller cuts the air into fine, uniform bubbles. Valuable mineral particles attach to the surface of these bubbles and rise to form a foam layer. Finally, the scraper device scrapes off the foam to complete the mineral separation. The entire process achieves self-aspiration and self-mixing through the equipment's own structural design, featuring simple operation and stable separation efficiency.

3. What technology is it made with?

3.1 Core Structural Technology

EPIC has integrated multiple patented technologies into the structural design of Self-Aspirated Mechanical Flotation Cells to ensure superior equipment performance. The tank body adopts an arc-bottom design optimized by fluid dynamics, which minimizes slurry deposition. The rotor-stator system is equipped with an open-type impeller with optimized blade angles, enhancing agitation efficiency. Wear-resistant components such as the impeller and cover plate are manufactured using precision casting of high manganese steel, improving wear resistance by 30%-50% compared to ordinary materials and effectively extending the equipment's operational cycle.

3.2 Manufacturing Standards and Certifications

To ensure product quality aligns with international standards, EPIC Self-Aspirated Mechanical Flotation Cells strictly adhere to industry standards and certification requirements. The product complies with the JB/T 14328-2021 industry standard and is certified by the ISO9001:2015 quality management system. Backed by 1 invention patent and 20 utility model patents, the equipment meets leading industry standards in design, production, inspection, and other key links.

3.3 Key Process Advantages

The precision manufacturing of the equipment relies on EPIC's strong production capabilities. It employs imported CNC equipment for precision machining, ensuring the rotor-stator gap accuracy is ≤6mm. This guarantees the stability and efficiency of the equipment during operation, reducing energy consumption and failure rates.
