The Application of Rotary Vibrating Screen in Magnesium Powder Screening

July 24, 2025

The Characteristics and Applications of Magnesium

Magnesium is a light, silvery-white alkaline earth metal with the chemical symbol Mg and atomic number 12. As the eighth most abundant element in the Earth's crust, magnesium plays a crucial role in various industrial fields due to its unique physical and chemical properties.

In industrial production, magnesium is typically in the form of powder or granules, for instance. Different applications have strict requirements for the particle size distribution of magnesium powder, which makes efficient screening equipment an indispensable part of the magnesium powder processing process.

The Working Principle and Advantages of the Circular Vibrating Screen

The rotary vibrating screen is a highly efficient and precise screening equipment, especially suitable for the screening treatment of fine powder materials like magnesium powder. To elaborate, its working principle is based on the three-dimensional vibration principle:

  1. Vibration source: The excitation force is generated by the vibration motor at the top.
  2. Movement trajectory: The material performs a three-dimensional spiral movement on the screen surface - a combination of horizontal circular motion and vertical throwing motion.
  3. Screening process: The material spirals from the center to the outer edge, and the fine particles pass through the mesh holes and fall, while the coarse particles move along the screen surface to the discharge port.

Unique advantages of rotary vibrating screen in magnesium powder screening:

High-efficiency screening: Large processing capacity, with screening efficiency reaching 90-95%.

Fine grading: Can precisely separate magnesium powder particles ranging from 20μm to 5mm.

Sealed design: Fully enclosed structure effectively prevents magnesium powder oxidation and dust overflow.

No contamination: Made of stainless steel or special coating to avoid metal contamination.

Customizable: Parameters such as the number of screen layers and inclination angle can be adjusted according to the characteristics of magnesium powder.

Full-line solution capability

Our company not only offers individual rotary vibrating screen equipment, but also has the capability to provide complete production lines for magnesium powder processing. For example, take the magnesium powder production line we designed and implemented for a Japanese client. This production line includes:

  1. Vacuum feeding system: Ensures safe and dust-free transportation of magnesium powder.igh-efficiency screening system: Multi-level rotary vibrating screens ensure precise particle size control.
  2. Buffer silo: Equipped with nitrogen protection device to prevent magnesium powder oxidation.
  3. Ton bag packaging machine: Automatic weighing and packaging to improve packaging efficiency.
  4. Central control system: Achieves full-line automated operation and monitoring.
