Product Overview: CJ125 Modular Primary Jaw Crusher
The CJ125 Jaw Crusher combines advanced modular design, hydraulic adjustment, and optimized kinematics to maximize productivity and uptime. Designed to process feed sizes up to 900×1250 mm with throughput ranging from 290 to 845 t/h, it offers durable performance and low operating costs, ideal for hard rock processing and high-volume aggregate production.
Key Features of the CJ125 Jaw Crusher
1. Modular Welding-Free Structure for Enhanced Durability
The non-welded modular frame eliminates stress concentration points, increases structural integrity, and simplifies transportation and assembly, reducing long-term maintenance costs and downtime.
2. Hydraulic Toggle & Discharge Adjustment System
Equipped with a fully hydraulic toggle plate and discharge opening adjustment (70–250 mm), enabling quick, precise setting changes without manual intervention, optimizing output size and throughput.
3. Large Toggle Plate Inclination for Higher Crushing Force
The optimized toggle plate angle increases crushing impact in the lower chamber, improving reduction efficiency and boosting capacity, especially for medium-hard to hard materials.
4. High Crushing Ratio with Reliable Compression Action
Utilizes a robust eccentric shaft and moving jaw mechanism to deliver consistent high compression crushing, effectively reducing large feed into uniform, specification-ready product.
5. Wear-Resistant Components for Extended Service Life
Constructed with high-strength alloy jaw plates, durable liners, and heavy-duty bearings, the CJ125 withstands abrasive conditions and continuous operation with minimal wear and easy part replacement.
Applications of the CJ125 Jaw Crusher
1. Mining Primary Crushing for Metallic Ores
Handles iron, copper, gold, and other ores in medium to large mining operations, providing reliable size reduction before further processing.
2. Quarry & Hard Rock Aggregate Production
Processes granite, basalt, limestone, and other hard stones into primary crushed aggregates for construction, road base, and rail ballast.
3. Large-Scale Construction & Infrastructure Projects
Supplies consistent, high-volume crushed stone for highways, dams, ports, and commercial building foundations.
4. Recycling of Demolition & Concrete Waste
Capable of crushing reinforced concrete, masonry, and C&D debris into reusable aggregates for sustainable construction and landfill reduction.
5. Industrial Mineral & Slag Processing
Crushes industrial minerals, furnace slag, and synthetic aggregates for use in cement, ceramics, and construction materials.
