# New Crushing & Grinding Technologies
## Emerging Innovations in Mineral Processing
Recent advancements in crushing and grinding technologies are transforming mineral processing operations with improved efficiency, energy savings, and environmental benefits.
Key Developments:
1. High Pressure Grinding Rolls (HPGR)
– Energy savings of 20-50% compared to conventional circuits
– Produces more favorable particle shapes for downstream processes
– Increasingly used in hard rock mining applications
2. Vertical Roller Mills (VRM)
– Lower energy consumption than ball mills
– Compact footprint and reduced noise levels
– Growing adoption in cement and industrial minerals sectors
3. Stirred Media Mills
– Ultra-fine grinding capabilities
– Higher energy efficiency for fine particle production
– Used in specialty minerals and hydrometallurgical applications
4. Sensor-Based Sorting
– Pre-concentration before grinding reduces energy waste
– Uses XRT, laser, or other sensors to reject waste rock early
– Can reduce grinding circuit feed by 30-50%
5. Digital & Automation Technologies
– Advanced process control systems optimize grinding performance
– AI-powered predictive maintenance reduces downtime
– Real-time particle size monitoring with smart sensors
6. Eco-Efficient Comminution
– Microwave-assisted breakage showing promise in lab tests
– Electropulse fragmentation technology under development
– Biomimetic approaches inspired by natural crushing mechanisms
These technologies are helping mining operations reduce their energy footprint (comminution typically consumes 3-5% of global electricity) while improving recovery rates and operational flexibility.
