Iron ore crushing and screening process
2. Iron ore screening process: Iron ore screening equipment generally uses a circular vibrating screen to screen the materials after the second crushing. Generally, materials with a size of 10mm or less can be screened for dry selection. After screening, materials with a size of 10-40mm enter the fine crusher for fine crushing.
