What is HPGR • High Pressure Grinding Rolls (HPGR) • Similar to the typical fixed roll crusher • Force applied to push one roll towards the fixed roll and raise pressure between the rolls • Force on the material mainly compressive • Introduces micro cracking – favourable for further comminution
We deliver tough and reliable crushers that are designed to handle a wide range of crushing applications from primary, secondary, and tertiary hard rock crushing to mixed demolition debris, crushed or broken concrete and asphalt, sand, gravel and quarried stone.

Jul 13, 2016· The most common HPGR based circuit involves feeding primary crusher product to a secondary crushing circuit with of cone crushers in closed circuit with screens, followed by tertiary crushing with HPGRs, also operating in closed circuit with screens. The product of these two stages of crushing and screening then passes to secondary milling.
The Coalition for Energy Efficient Comminution (CEEC) has been established and is supported by a broad range of mining sector companies keen to accelerate awareness, knowledge transfer and, by implication, improve energy and cost outcomes in the substantive area of comminution.
Comminution in HPGR is a result of high inter-particle stresses generated when a bed of solids are compressed while moving down the gap between two pressurized rolls. The priority that HPGR can generate fine products followed by grinding in ball milling, puts a competitive pressure on the application in semi-autogenous (SAG) mills.
High Pressure Grinding Rolls (HPGR) ... which is an important distinction as compared to crushers, for example. ... Furthermore, they can also be used as tertiary and/or quaternary crushing stages or in the pebble-crushing stage to improve downstream milling performance. Value for Money .
of HPGR in the comminution circuit to reduce the feed size produced by the tertiary crushers, in order that the existing rod mills could be converted to ball mills; thus achieving the 30,000 tonnes per day production. The study was based on the Köppern test report (“High Pressure Comminution Testwork
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

a tertiary crusher (e.g. cone crusher) would produce. The reason is that the compressive force not only acts on the coarse end of the PSD, but throughout the particle bed on both coarse and fine particles, including the fine particles derived from the initially coarser fractions. A wide range of ores appear to generate products of a similar P80.
Our extensive range of crushers efficiently produce high-valued, shaped and sized material. Our tough and reliable crushers are designed to handle a wide range of crushing applications from primary, secondary, and tertiary hard rock crushing to mixed demolition debris, crushed or broken concrete and asphalt, sand, gravel and quarried stone.
HPGR was used to replace a conventional tertiary and quaternary crusher. At that time HPGR technology was considered new to this type of installation, and extensive test work and studies were conducted to support the plant design. The grinding circuit was designed to include primary gyratory crushing, secondary cone crushing, and a Humboldt

WEIR Minerals KHD crusher High Pressure Grinding Rolls – Crushing and grinding for ore and minerals processing. High Pressure Grinding Rolls (HPGR) were introduced as a new grinding technology in 1984. Since then, they have been successfully installed in a large number of plants throughout the world, mainly for cement and limestone.
The evolution of HPGR technology HRC™ HPGR 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, ... • Tertiary crusher, followed by a ball mill or
high heap gold leach recoveries, HPGR as a tertiary crusher has been shown to reduce overall capital and operating costs in addition to improving gold recovery. An excellent case of this is the Soledad Mountain described by Klingmann (2005) already referred to above. HPGR can …
An HPGR cannot replace a SAG mill. Also required to get the feed into the HPGR is a secondary crusher(s) and perhaps a tertiary crusher(s). The HPGR is often a quaternary crushing device which is the reason that the footprint for an HPGR plant is so large.
High pressure grinding rolls are an energy efficient grinding solution, and now has improved this technology even further. The HRC™, our innovative approach to HPGR technology, is like no other HPGR on the market.
