1. Hammer crushers and impact crushers, primarily use impact.
2. Jaw crushers, cone crushers, and roller crushers, primarily use compression.
3. Roller mills and roller grinders, primarily use a combination of compression and grinding.
4. Ball mills, rod mills, vibratory mills, and jet mills, primarily use a combination of grinding and impact.
Generally, jaw crushers and cone crushers are used for coarse crushing, cone crushers, hammer crushers, and impact crushers for medium crushing, roller crushers for fine crushing, and ball mills, vibratory mills, and jet mills for grinding. However, this is not absolute; some machines are suitable for both coarse and medium crushing.
