FAQs for Raymond Mills and Other Grinding Mills-Page 2

The vibrating feeder is suitable for conveying granular and lump materials; the belt feeder is suitable for conveying granular, powdery, and lump materials; and the screw feeder is suitable for conveying powdery and small granular materials. For large lump materials and high-moisture materials, the use of a screw feeder is strictly prohibited.

Jaw crusher is mainly used for primary crushing; impact crusher, hammer crusher and cone crusher are commonly used for secondary crushing; tertiary crushing mainly uses cone crusher and sand making machine. For high-moisture materials, select jaw crusher; for high-hardness materials, select cone crusher; for particle shape optimization, select impact crusher and sand making machine.

Magnetic separators are the key equipment for efficient iron removal in Raymond mills. For front-end separation, use overhead self-cleaning magnetic separators or magnetic pulleys. For mid-end separation, use pipeline permanent magnetic separators. For back-end purification, use high-gradient electromagnetic separators.
