HRC™e grinding systems are pre-engineered to deliver rapid, safe and cost-effective solutions with readily scalable and configurable modules for both greenfield and brownfield projects. The range of solutions for HRC™e grinding systems include mobile, skid mounted and modular systems.
Scalable, configurable and sustainable HPGR grinding solutions.
Highly scalable
Pre-designed modules with flexible configuration for multiple HRC™e or GFF screens
Cost-effective
Reduced plant footprint with lower OPEX due to no grinding media required, reduced circulating load and energy demand
Reduced shutdown time and improved productivity
HRC™e Solutions enable faster commissioning, higher utilization, and more stable grinding
Driving the limits of grinding performance
Proven HPGR technology engineered for performance
The HRC™ and next-generation HRC™e set the benchmark for energy-efficient and high-throughput grinding. Designed to eliminate edge effect, improve availability and simplify maintenance, HRC™ and HRC™e bring unmatched performance advantages to the grinding circuit.

HRC™e grinding systems
HRCTMe Grinding systems extend far beyond the machine itself. Our solution can integrate conveying, tramp management, structural elements and service infrastructure, all delivered in a pre-engineered and configurable module.
Scope of supply:
HRC modules can include:
- HRC with feed chute, hopper and auxiliaries
- Feed system including stockpile, draw down feeder
- Conveyors, metal detector and tramp removal system
- Circuit surge bin for circulation load management and circuit recovery from emergency stop
- Overhead crane, service frame, or service trailer
- Optional enclosing building or housing structure available
Modular design:
- Configurable for single or multiple HRC units
- For greenfield and brownfield sites
- Mobile, skid-based, or relocatable versions available
- Supports future expansion without major redesign
- Open circuit, direct closed circuit and reverse closed circuit options
Execution advantages:
- Faster layout development
- Reduced site work through pre-assembly
- Higher consistency in operation and maintenance
- Enables circuit expansion through mobile/skid solution for relocation, reconfigurable for various flowsheets
Enhancing HRC Grinding System performance with Metso GFF Series™ screens
With over 100 units installed worldwide alongside HPGR systems, proven GFF screening technology operates reliably in both wet and dry conditions, enabling precise particle classification at high throughput and ensuring consistent performance even in challenging applications. This makes GFF screens an ideal partner for HRC.
- Improves overall classification efficiency by 20–30% compared to traditional banana screens
- Effective fine removal increases micro-void volume, enhancing rock breakage under compression
- Ensures better stratification, resulting in significantly more efficient fine screening
Proven operational excellence
- Able to make a separation as fine as 0.3 mm
- Unit capacity can reach up to 2500 tph while maintaining 85%–90% efficiency
- Features an ultra-low maintenance schedule, requiring approximately 2 to 4 hours of regular maintenance for an average of every 10,000 hours of exciter life
Screening modules
Metso MF and GFF screen technology complement HRC grinding systems to unveil the HPGR’s highest efficiency. Due to ore variability in terms of particle size distribution and hardness, the screen selection imposes a new challenge in terms of size and number of screens when incorporating the screens into the HRC grinding system. Metso HRC grinding systems are built on our solid HRC test data base and screening knowledge base — our screen module is scalable and configurable to accommodate this variable.
Scope of supply. Screen modules can include:
- Feed storage system with bins and dust control system
- Screen feed system with weigher, belt feeder or pan feeder and tramp removal magnet
- Screen with special pulping feed chute, oversize and undersize discharge chutes
- Oversize protection screen deck to remove oversize particles that can lead to HRC roller damage
- Undersize wet system using pump module (part of the Grinding Classification System)
Flowsheet integration:
- Seamlessly integrated with downstream milling circuit
- Suitable for both dry screening and wet screening circuits
- Enables fast layout development
- Allows for needed future expansion and enables process flexibility as the flow sheet changes
Technology comparison
HPGR technology is ideal for customers who
• have bottlenecks in pebble crushing
• need a high-tonnage, lowenergy flowsheet solution
• are transitioning to harder ores
• need debottlenecking for tertiary crushing
• are looking at reducing circulation load
• need to increase grinding capacity with more fines generation
