HRC™High Pressure Grinding Rolls Expect results

The evolution of HPGR technology High pressure grinding rolls are preferred for their energy efficiency and flexibility in ore processing. Metso’s unique take on this technology, the HRC™ HPGR, delivers even bigger – as the most advanced high pressure grinding roll on the market. The technology HPGRs utilize two counter-rotating tires – one fixed and one floating – in order to effectively crush ore. Hydraulic cylinders apply very high pressure to the system, causing inter-particle comminution as the feed travels between the two tires. A focus on energy efficiency The basic operating principle...

Applications Common circuits When selecting an HRC model, mining operators should consider ore top size, capacity and overall circuit design. The HRC is best suited for crushing in high-tonnage, hard rock applications. Common circuits utilize high pressure grinding rolls in a number of ways: The HRC is ideal for crushing hard rock with relatively low moisture content and can provide superior results in the size reduction of a variety of minerals. Currently, HPGR technology is successfully operating in a number of applications, including diamonds, iron ore, copper, gold, platinum, molybdenum and...

Upgrade your approach to hard rock crushing When it comes to comminution technology, the demand for efficiency drives product development. Metso has committed its experts to engineering and manufacturing comminution equipment that is the most efficient on the market, and this was the goal in the creation of the HRC.

Innovative design – unique strengths The unique, conceptual design of the HRC enhances this technology to the fullest extent, optimizing the reliability, capacity and energy efficiency of the machine. The bottom line: Our design – supported by Metso’s service and expertise – works harder for you and your budget. Increased availability The patented Arch-frame in the HRC provides an even gap setting across the width of the tires. This is created by a torsion tube that connects both bearings, enabling the frame to pivot in its base and absorb any unbalanced loads caused by a segregated feed. The...

Superior maintenance and safety Metso equipment is designed to help you protect your investment. From wear parts that are designed for longevity to our industry-leading safety features, the HRC ensures quick, simple maintenance and superior operational safety. Increased component longevity and ease of maintenance Anti-skewing Arch-frame: The anti-skewing frame extends the wear life of the roller bearings and tire surface. It prevents misalignment, which typically causes damage to these wear parts. Safety you can count on Transporter: The transporter enables a safe and quick change-out of the...
