Stone crushers and gravel equipment are essential in mining, construction, and road-building industries for processing raw materials into usable aggregates. Here’s an overview of the key equipment and their functions:
1. Types of Stone Crushers
Stone crushers break down large rocks into smaller gravel, sand, or dust for construction and industrial use. Common types include:
– Jaw Crusher – Primary crushing; reduces large rocks to medium-sized stones.
– Impact Crusher – Uses impact force to crush materials (good for softer rocks).
– Cone Crusher – Secondary/tertiary crushing; produces finer aggregates.
– Hammer Crusher – For brittle materials like limestone or coal.
– Roll Crusher – Compresses material between two rotating rollers.
– Mobile Crusher – Portable units for on-site crushing (tracked or wheeled).
2. Gravel Processing Equipment
After crushing, gravel undergoes further processing:
– Vibrating Screen – Separates crushed stone into different sizes (e.g., 0-5mm, 5-20mm).
– Sand Washer – Cleans dust and impurities from sand/gravel.
– Conveyor Belts – Transport materials between crushers, screens, and stockpiles.
– Feeders (Vibrating/Grizzly) – Regulates material flow into crushers.

3. Key Applications
– Road construction (base layers, asphalt mixes)
– Concrete production
– Railway ballast
– Landscaping and drainage systems
4. Leading Manufacturers
Top brands in stone crushing & gravel equipment include:
– Metso, Sandvik, Terex
– Kleemann, Eagle Crusher
– Liming Heavy Industry (China)
– SBM Machinery
5. Considerations When Choosing Equipment
– Material hardness (granite vs. limestone)
– Required output size & capacity
– Mobility needs (fixed plant vs. mobile crusher)
– Environmental regulations (dust/sound control)
