Compression Crushing
Compression crushing involves the application of a compressive force to the material between two opposing surfaces. This force fractures the material by overcoming its compressive strength. Compression crushers are commonly used for fine crushing and can produce a more uniform particle size distribution.
Advantages:
- Lower energy consumption compared to impact crushing
- Produces a more uniform particle size
- Suitable for materials with low moisture content
Limitations:
- Lower reduction ratios compared to impact crushing
- May require multiple passes to achieve desired particle size
- Can be sensitive to the presence of foreign objects
Shear Crushing
Shear crushing involves the application of a shearing force to the material. This force causes the material to break along its planes of weakness. Shear crushers are commonly used for fine crushing and are particularly effective in producing a fine and uniform particle size distribution.
Advantages:
- Produces a fine and uniform particle size
- Can handle materials with high moisture content
- Suitable for materials with a high degree of hardness
Limitations:
- Lower reduction ratios compared to impact and compression crushing
- May require multiple passes to achieve desired particle size
- Can be sensitive to the presence of foreign objects
