This single screen design cannot comprehensively and accurately screen particles of different particle size ranges when facing reduced iron powder with complex particle size distribution. At the same time, the screening mechanisms used by these screening devices are often extremely complex. The complex structure not only increases the manufacturing and maintenance costs of the equipment, but also makes the equipment prone to failure during operation. UTILITY MODEL CONTENT
