HRC™e high pressure grinding rolls (HPGR)

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 HRC™e 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 HRC™e 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 HRC™e 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.
