grinding rolls enable improved material feed and up to 20% more throughput than conventional HPGRs. What's more, the machine's specific energy consumption is reduced by around 15%. At the same time, the uniform pressure profile in the milling gap results in better grinding and more even roller wear. This prolongs the service

HRC™3000 is a new generation high-pressure grinding roll that eliminates issues found in traditional HPGRs, allowing the mining industry to reach a new level of energy efficiency. The world's largest HPGR was installed at Freeport-McMoRan's Morenci site in Arizona, USA.
Combining a polycom ® high-pressure grinding roll and a static-dynamic sepol ® separator in a finish grinding plant for raw material increases energy efficiency significantly. Each polysius ® grinding plant is custom-engineered based on the raw material properties, production requirements and local conditions.
Polysius polycom roller press high-pressure grinding roll one of the principal reasons for the outstanding success of the high-pressure grinding roll …
The bearing units are mounted on concrete foundations. The hydraulic system is located directly at the floating bearing of each grinding roller. The bearing block of the floating bearing was adopted from the well-tried design of the high-pressure grinding roll and the profile of the grinding elements was adopted from the proven Polysius roller ...
By adding a Polycom high-pressure grinding roll, the throughput of existing plants can be increased by as much as 150% while simultaneously reducing the power consumption by up to 20%. Large Polycom units provide a high throughput potential (600 to 1200 mt/h).
High pressure comminutionThe economic and gentle processing solution. 60 % of the highpressure grinding rolls installed in the minerals industry are from Polysius: the POLYCOM ® operates convincingly all around the world, comminuting copper ore, gold ore, iron ore, diamond ore, platinum ore, coal, granulated blast furnace slag, limestone ...
It's here, then, where Polysius is pushing the benefits of HPGR—or high pressure grinding rolls—as an alternative to other forms of crushing and grinding. But while the Polysius empire was finding ready customers for its new technology in the cement world, finding takers in the minerals business was proving frustratingly slow.
A grinding roll for use in a material bed roll mill for the comminution of brittle material has a cylindrical body in the periphery of which are alternating grooves and lands. To the exterior of each land is secured a wear strip. The grooves of the confronting rolls may be directly opposite one another or the grooves may be offset axially so that the grooves in one roll confront a land …

Polysius offers: xforged, hardfaced rolls, xchill cast tyres made of bainite, xchill cast tyres of compound casting. The profiles welded onto the grinding rolls provide optimum draw-in conditions for the feed material and minimise the relative movement between the comminuted material and the roll surface.
The Polysius high pressure grinding roll POLYCOM has very impressive credentials from its many years of application in production plants of the minerals industry. Gold ore is an extremely hard material that causes severe grinding element wear. It is therefore a significant advance that a new roll tyre concept introduced by Polysius has ...
Anglo Platinum's Chris Rule and colleagues stated that the Polysius Polycom HPGR has come of age, offering appropriate roll wear-abatement technology and proving itself as an alternative comminution device for hard-rock applications. The Polycom can be specified as to roll diameter, roll width, roll speed, hydraulic pressure and bearing size.
