Metso High pressure grinding rolls (HPGR)
Product Feature
Features
High pressure grinding rolls are an energy efficient grinding solution, and now Metso has improved this technology even further. The HRC™, our innovative approach to HPGR technology, is like no other HPGR on the market.
Main features of the HRC™ HPGR are:
- Patented anti-skewing Metso Arch-frame
- Tungsten carbide studded tires with patent pending HRC™ HPGR flanges
- Feed hopper with guide plates to direct the feed into the crushing zone
- Hydraulic cylinders can be adjusted to provide the optimal crushing force
- Variable speed drive train suitable to run between 110% to 30%* full speed (*select sizes run between 110% to 50% full speed)
- Dust enclosure to provide a dust and noise barrier while also offering added protection for the main bearings
Benefits
- Increased circuit efficiency and capacity - flanges direct material to the crushing zone, maximizing the amount of ore crushed. In a closed circuit pilot scale operation, this amounted to over a 20% increase in circuit capacity and over a 10% decrease in circuit specific energy
- Improved availability – patented Arch-frame eliminates downtime associated with skewing
- Increased reliability – anti-skewing Arch-frame prevents bearings from being damaged due to misalignment
- Reduced operating costs – energy efficiency, longevity of wear components including the studded tires and no use of grinding media all contribute to low operating costs
- Flexible operating parameters – speed and pressure can be adjusted for changing ore conditions and downstream circuit demands
