Description

Technical Field

[0001] This utility model relates to the field of particle steel production technology, and in particular to a metal particle screening device. Background Technology

[0002] The particle size distribution of particle steel has a significant impact on its performance. Screening can control the particle size range of metal particles, ensuring that the product meets specific application requirements, such as flowability and bulk density. Screening can also reduce unnecessary energy consumption during production. For example, using metal particles with uniform particle size can accelerate the melting process and reduce energy consumption during smelting.

[0003] Common metal particle screening devices typically use oscillation to screen metal particles, accelerating their fall. For example, Chinese patent CN218573830U, "A Metal Particle Screening Device," uses rotating shredders to further process lead waste, ensuring its size. Simultaneously, the up-and-down oscillation of the filter screen effectively accelerates the fall of waste from the screen, preventing clogging. However, metal particles are prone to agglomeration due to transportation and environmental factors, prolonging the material's residence time in the screening machine and increasing the total screening time. This not only reduces production efficiency but may also increase energy consumption and production costs. Therefore, this paper proposes a metal particle screening device to address these issues.
