A stone crusher product line refers to a complete set of equipment and processes designed to crush large stones or rocks into smaller sizes for various construction, mining, and industrial applications. Here’s an overview of a typical stone crusher production line:
—
1. Main Components of a Stone Crusher Production Line
# (1) Primary Crushing Equipment
– Jaw Crusher: Breaks large rocks into smaller pieces (150–350 mm).
– Gyratory Crusher: Used in high-capacity mining operations.
# (2) Secondary Crushing Equipment
– Cone Crusher: Produces finer aggregates (20–60 mm).
– Impact Crusher: Suitable for softer rocks (limestone, recycled concrete).
# (3) Tertiary & Fine Crushing (Optional)
– Vertical Shaft Impact (VSI) Crusher: Produces sand and fine aggregates (<10 mm).
– Hammer Crusher: For brittle materials like coal and limestone.
# (4) Screening & Classification
– Vibrating Screen: Separates crushed stones into different sizes (e.g., 0–5mm, 5–10mm, 10–20mm).
# (5) Conveying System
– Belt conveyors transport materials between stages.
# (6) Auxiliary Equipment
– Dust control systems (bag filters, water sprayers).
– Storage bins and silos.

2. Typical Production Process
1. Feeding – Large rocks are fed into the primary crusher via a vibrating feeder.
2. Primary Crushing – Jaw/gyratory crushers reduce size to ~150–350mm.
3. Secondary Crushing – Cone/impact crushers further break down to ~20–60mm.
4. Screening – Vibrating screens classify materials by size; oversized stones are recirculated.
5. Tertiary Crushing (if needed) – VSI or hammer mills produce fine aggregates/sand.
6. Final Products – Stockpiled for use in construction, road building, or concrete production.

3. Common Applications of Crushed Stone
– Construction Aggregates: Concrete, asphalt, road base layers.
– Railway Ballast: Supports train tracks with durable crushed rock.
– Landscaping &
