lime ore jaw crusher

A lime ore jaw crusher is a primary crushing machine used to break down limestone (lime ore) into smaller, manageable sizes for further processing. Here’s a detailed breakdown of its features, working principle, and applications:

Key Features of Lime Ore Jaw Crusher

1. Robust Construction
– Made of high-quality materials (e.g., manganese steel jaws) to withstand abrasion from limestone.
– Heavy-duty frame ensures durability in harsh mining or quarry environments.

2. Adjustable Discharge Size
– The gap between the fixed and movable jaws can be adjusted to control the output size (typically 10–350 mm).

3. High Crushing Efficiency
– Optimized crushing chamber design ensures effective reduction of lime ore with minimal energy consumption.

4. Low Maintenance
– Simple structure with fewer wear parts compared to other crushers.

5. Versatility
– Can handle both soft and moderately hard limestone varieties.

Working Principle

• The motor drives the eccentric shaft, causing the movable jaw to move back and forth.
• Limestone is fed into the crushing chamber and compressed between the fixed and moving jaws.
• Crushed material exits through the discharge opening at the bottom.

Applications

• Primary crushing in limestone quarries, cement plants, and construction sites.
• Preparation of lime ore for rotary kilns or further grinding mills.
• Production of aggregates for road construction and concrete.

Advantages Over Other Crushers

✔ Higher reduction ratio compared to gyratory or cone crushers.
✔ Lower operational costs due to simple mechanics.
✔ Suitable for both stationary and mobile crushing plants.

Common Models & Specifications

Maintenance Tips

• Regularly check jaw plates for wear and replace them when necessary.
• Lubricate bearings frequently to prevent overheating.
• Ensure proper alignment of belts/pulleys for smooth operation.
