AKSA MAGNET Fluid Bed Separator - Verimli ve Hassas Ayırma Çözümleri

Aksa Fluid Bed Separator

DESCRIPTION

The AKSA FLUID-BED SEPARATOR utilizes fundamental physical principles—fluidization, ultrasonication, and electromagnetism—to classify and separate materials.

With rising mineral prices and increasing costs of magnetic equipment, many industries have begun investing in separation technologies capable of performing magnetic and non-magnetic classification. These advanced separators have become widely preferred across multiple sectors due to their high-tech capabilities.

Supported by advanced control software, the AKSA FLUID-BED offers effective pre-concentration by exploiting density differences and magnetic susceptibility characteristics of materials.

WORKING PRINCIPLE

The AKSA FLUID-BED SEPARATOR (AFB) is an innovative technology that enables the separation of materials into three different products. It is a hydraulic classifier that uniquely combines the core principles of ultrasonication, electromagnetism, and gravitation with fluidized-bed technology.

A schematic diagram of the AFB is shown in Figure 1. The feed material is suspended in a separate tank and, together with water, flows into the upper body of the AFB through a cyclone at a predetermined velocity. The material then moves downward through the system until it encounters an upward water flow.

The upward water velocity is adjusted to fluidize the lighter particles, allowing heavy particles to settle downward while lighter particles rise. Ultrasonication prevents fine light particles from settling and prevents agglomeration. Material with high magnetic susceptibility is pulled downward again by an adjustable electromagnetic force.

To achieve optimal separation and classification, water flow pressure is adjusted so that heavy particles are discharged from the bottom of the machine. Lighter particles overflow from the first section and move into the second chamber, where they again encounter upward water flow. Heavy (finer) particles in the second chamber discharge through valves at the bottom, while lighter material moves into the third chamber. Since water pressure in the second chamber is lower than in the first, the lightest material remains fluidized and flows over into the final chamber.

A periodically activated valve system allows material to exit from the bottom of the machine.
AFB is used for classification and density-based separation in iron ore, coal, industrial minerals, chromite, and slag processing industries. The unit offers a capacity range of 100 t/h to 800 t/h.
