Evolution on proven grinding performance

How do you improve the industry standard for HPGRs? The HRCe HPGR has done it.

Using proven grinding technology with a customer-focused evolution in design, the HRCe HPGR brings maximum productivity and improved energy efficiency for superior grinding efficiency.

Check out the video to get a deeper look into the evolution of the industry standard for HPGRs.

Superior grinding and energy efficiency

Challenges for grinding are arising. Installation and energy costs are increasing, declining ore grades, stricter regulations and more. As grinding plays an essential role in minerals processing, the need for innovation in grinding is critical to circuit optimization. 

The Metso Outotec HRCe high pressure grinding rolls (HPGR) is combining proven technology with a customer-focused evolution for superior grinding and energy efficiency to help optimize your operations.

Maximum productivity

The HRC™e HPGR takes proven technology and enhances it. The high throughput comes from the elimination of the edge effect with the flange design, which will ultimately maximize the amount of crushed material. With the skew control system you will find faster restarts and minimize downtime from skewing events. 

The HRCe also comes with a large feed size acceptance and improved energy efficiency compared to similar HPGRs. Boosting the efficiency and cost savings. 

Ease of maintenance

The HRCe HPGR creates a safe and simple maintenance operation. The edge segments replacement process is simple due to the bolted design and flange integration. The dust enclosure separates the crushing zone from critical mechanical components within the machine.

The unique feed chute also comes with control gates for quick maintenance and reliable start up. These features and reduced tire wear life leads to low downtime.

Skew control system

The skew control system is a field-proven mechanical solution that balances the loads by the distributor device ensuring the tires remain parallel for maximum efficiency. The system is also is self monitoring and evaluates skewing, segregation and mechanical condition of the parts.

The skew control system increases availability and reliability of the machine by controlling skewing events and allows for flange rolls assembly.

Tire assembly flange rolls

Metso Outotec is the only OEM to successfully operate reliable flanges. The flange rolls eliminate the edge effect by evenly distributing the material, which also maximizes the amount of crushed material during the process. 

The HRC™e HPGR flange rolls bring improved energy efficiency, reduces the circulating load and increased tire life.
