A sand and gravel crusher is a machine designed to break down large rocks, boulders, or gravel into smaller pieces for use in construction, landscaping, and other applications. These crushers are essential in aggregate production for making sand, crushed stone, and gravel used in concrete, asphalt, and road base materials.
Types of Crushers Used for Sand and Gravel Production
1. Jaw Crusher
– Primary crushing stage
– Breaks large rocks into smaller chunks
– Good for hard and abrasive materials
2. Cone Crusher
– Secondary or tertiary crushing
– Produces finer, more uniform material
– Ideal for medium-hard to hard rock
3. Impact Crusher (HSI/VSI)
– Horizontal Shaft Impact (HSI) Crusher: Good for softer materials like limestone
– Vertical Shaft Impact (VSI) Crusher: Produces high-quality sand (artificial sand) by crushing rocks into fine particles
4. Gyratory Crusher
– Used in large-scale operations (quarries)
– High-capacity primary crushing
5. Roll Crusher
– Used for fine crushing of softer materials like coal or clay
Applications of Crushed Sand and Gravel
– Concrete production (fine & coarse aggregates)
– Asphalt mixtures
– Road base & sub-base layers

ainage systems (filter material)
– Landscaping & decorative stone
Key Considerations When Choosing a Crusher
– Material hardness & abrasiveness (granite vs. limestone)
– Desired output size (sand vs. gravel)
– Production capacity needs (small vs. large-scale operations)
– Mobility requirement (stationary vs. portable crushers)
