The CS840i stationary cone crusher represents a revolutionary advancement in crushing technology, combining a double-chamber design with robust engineering to deliver unmatched efficiency and versatility. Designed for heavy-duty applications, this crusher is ideal for mining, quarrying, and aggregate production. Its innovative architecture ensures high productivity, reduced downtime, and adaptability to diverse material types.
Working Principle of the CS840i Double-Chamber Cone Crusher
Dual Crushing Zones for Enhanced Efficiency
The CS840i stationary cone crusher employs a unique double-chamber design that divides the crushing process into two distinct stages: primary and secondary. The upper chamber handles coarse crushing, breaking large feed materials into manageable sizes. The lower chamber then refines these particles to the desired final product specifications.
This dual-zone approach minimizes recirculation loads and reduces energy consumption by 15–20% compared to traditional single-chamber crushers. The hydraulic adjustment system allows operators to fine-tune the discharge setting dynamically, ensuring consistent output quality even with fluctuating feed conditions.
Key Technical Parameters of the CS840i Cone Crusher
Engineered for Performance
The CS840i stationary cone crusher is built to handle demanding workloads. Below are its core technical specifications:
Max Feed Size 450 mm (17.7 in)
Capacity 500–1,200 t/h
Motor Power 315 kW (422 hp)
Crusher Weight 24,200 kg (53,350 lbs)
Discharge Range 19–51 mm (0.75–2.0 in)
Chamber Options Coarse, Medium, Fine, Extra-Fine
These parameters make the CS840i double-chamber crusher suitable for processing hard and abrasive materials like granite, basalt, and iron ore, while maintaining high throughput and low operational costs.
Application Scenarios for the CS840i Double-Chamber Crusher
Mining and Quarrying Operations
The CS840i stationary cone crusher excels in large-scale mining and quarrying environments. Its double-chamber design allows for continuous processing of oversized rocks, reducing the need for primary jaw crushers in certain configurations. For example, in copper mines, the crusher’s ability to handle high-pressure crushing ensures efficient liberation of valuable minerals.
Aggregate Production for Construction
In aggregate plants, the CS840i cone crusher delivers uniformly shaped end products critical for road construction and concrete manufacturing. The dual chambers enable precise control over particle size distribution, meeting strict industry standards such as ASTM and EN.
Recycling and Secondary Crushing
The crusher’s adaptability extends to recycling applications, where it processes demolition waste, concrete, and asphalt. The hydraulic tramp release system protects the machine from uncrushable materials, making it ideal for urban recycling facilities with variable feed composition.
Advantages of the Double-Chamber Design in the CS840i
Operational Efficiency and Cost Savings
The CS840i’s double-chamber configuration optimizes energy use by distributing wear evenly across both crushing zones. This extends component lifespan and reduces maintenance frequency. Additionally, the crusher’s automated control system monitors performance in real time, adjusting settings to maximize output while minimizing downtime.
Flexibility Across Material Types
Whether processing soft limestone or hard quartzite, the CS840i stationary cone crusher adapts seamlessly. Operators can switch between chamber profiles (coarse to extra-fine) within minutes, making it a versatile solution for multi-product operations.
Case Study: CS840i Crusher in a Granite Quarry
