Small jaw crushers are compact, portable machines designed for crushing smaller quantities of hard and abrasive materials, such as rocks, ore, concrete, and demolition debris. They are commonly used in laboratories, construction sites, recycling applications, and small-scale mining operations.
Key Features of Small Jaw Crushers:
1. Compact Size – Easy to transport and operate in tight spaces.
2. Lower Power Consumption – Suitable for use with small electric motors or diesel engines.
3. Adjustable Output Size – Many models allow adjustment of the discharge opening to control the final product size.
4. Durable Construction – Made with hardened steel jaws or manganese liners for long-lasting performance.
5. Simple Operation – Minimal setup required compared to larger crushers.
Common Applications:
- Crushing samples in laboratories (geology, metallurgy).
- Recycling concrete and bricks for reuse.
- Processing small batches of minerals or ores.
- On-site demolition waste reduction.
- Feed size capacity (typically 2–6 inches).
- Required output size (fine or coarse aggregate).
- Power source (electric vs. diesel).
- Mobility needs (fixed vs. portable/track-mounted).
