Product Specification

Higher Crushing Ratio CJ Series Jaw Crusher is Ideal for Soft to Hard Rock Crushing

Product Features

The CJ Series Jaw Crusher is globally recognized for its reliability, adaptability, and innovative design, making it a preferred choice across industries. 

1. High Reliability

Features a unique modular and non-welded frame construction where two hot-rolled steel side plates are securely bolted to high-quality cast steel frames using precision-machined pins. This design eliminates durability reduction caused by stress concentration points (such as welds) when handling impact loads.

2. High Performance

The CJ series jaw crusher incorporates large eccentric throw and optimized toggle plate angle design, delivering greater effective stroke at the crushing chamber bottom.

3. Wide Adaptability

Offers customized jaw plate options with continuously optimized geometries and thicknesses, combined with carefully selected manganese steel alloys. This solution not only enhances production capacity but also reduces operating costs.

Convenient Operation

Equipped with a dual-wedge hydraulic discharge setting adjustment system. The crusher's discharge opening can be:

• Manually adjusted within minutes using provided tools

• Remotely adjusted in seconds, even during idle operation
  This system proves particularly effective when needing to clear the chamber during power interruptions or system load shutdowns.

Smoother Operation

Incorporates rubber damping devices and limit blocks that:

• Absorb peak vibration loads

• Allow controlled vertical and longitudinal movement

• Significantly reduce dynamic forces transmitted to the foundation
  The innovative mounting system eliminates anchor bolts, preventing potential foundation damage common with traditional installations.
