Rhodax ®

Product catalog summary

Overview
The document provides detailed information about the Rhodax® inertial crusher, a technology developed by Fives FCB. It highlights the crusher's ability to control grinding force, achieve a high reduction ratio, and add value to products.

Key Technologies
The Rhodax® crusher utilizes interparticle in-bed compressive grinding instead of traditional impact grinding. This method allows for fully controlled grinding force transmission into a bed of particles, suitable for both dry and wet processes.

Components and Process

A bowl driven in a circular horizontal motion by unbalanced masses.
A choke-fed operation facilitated by a suspended feeding chute.
A cone sub-assembly suspended to the bowl with a free-rotating cone liner.
A high-tuned machine mounted on filtering rubber shoes.

The process involves material undergoing compressive grinding followed by a gravity drop phase, with 3 to 6 cycles per pass through the crushing chamber.

Performance and Flexibility
The Rhodax® offers a higher liberation ratio at larger mesh sizes, better ore liberation along natural grain boundaries, and a superior flakiness index. It produces high-density concrete sand, reducing cement demand by at least 10%. The production of fines is controlled and adaptable through grinding force control, ensuring a constant final product independent of liner wear. The system supports both closed and open circuit production for fine and coarse products.

Cost and Engineering Advantages

Up to 50% energy savings.
Long-lasting high chromium cast iron wear parts.
Significant reduction in crushing stages and installed components.
No civil works required.
No dust emission, low noise, and low sensitivity to tramp iron.
Reduction ratio up to 100/1.
Compact installation with underload start and shutdown capabilities.

Applications
The Rhodax® is suitable for processing materials such as platinum, alumina, diamonds, gold, abrasives, ceramics, slags, iron ore, aggregates, and ferroalloys.

Technical Specifications
The document includes a range of Rhodax® models with varying feed sizes, installed power, nominal capacities, and nominal gaps, catering to different production needs.

Conclusion
The Rhodax® inertial crusher by Fives FCB offers advanced technology for efficient and flexible crushing and grinding, providing significant cost savings and engineering advantages.
