Heavy Duty Jaw Crusher for Mining

⚙️ Description of Jaw Crushers

NHI heavy duty jaw crusher is one of the main equipment for coarse and medium crushing of ores or rocks. It has the advantages of simple structure, reliable performance, easy operation, convenient maintenance and safe use. Jaw crusher can be divided into PEF compound swing jaw crusher (single toggle jaw crusher) and PEJ simple swing jaw crusher (double toggle jaw crusher) according to its structural characteristics.

Dual-series versatility: PEJ (double toggle) for heavy-duty operations, PEF (single toggle) for compact efficiency.

Innovative structure: Non-welded frames eliminate stress cracks, while wear-resistant tooth plates extend service life by 40%.

Energy-saving design: Rolling bearings reduce friction loss, achieving 20% higher productivity than traditional models.

⚙️ Benefits of Jaw Crushers

Replaceable components (e.g., jaw plates, bearings) reduce downtime by 30%.

Standardized modules enable quick customization for specific materials (hard rock, limestone, etc.).

Forged high-strength alloy steel frames resist fatigue under heavy loads, ensuring 99% operational stability.

Heat-treated eccentric shafts with balanced flywheels minimize vibration and noise.

Support fixed-base, mobile chassis, or integrated plant configurations.

Adapt to diverse terrains (mountainous mines, coastal plants) with anti-corrosion coatings.

Shock-absorbing Foundation

Design of floating shock absorption foundation. Strong practicality of the foundation and seamless replacement with the original foundation.

⚙️ FAQ of Jaw Crushers

1. How do jaw crushers work?

heavy duty jaw crushers work by using two jaws—one fixed and one movable—to crush material. As the movable jaw moves back and forth, it compresses the material against the fixed jaw, breaking it into smaller pieces.

2. What is a jaw crusher used for?

A heavy duty jaw crusher is mainly used for primary crushing of hard materials like stone, ore, and concrete. It prepares raw materials for further processing in mining, construction, and recycling industries.

3. What is the jaw crusher system in the mines?

In mining operations, the jaw crusher system is typically used at the front end of the crushing process. It reduces large mined rocks into manageable sizes for secondary crushers or grinding mills.
