High Pressure Grinding Roll Operating Platform

HPGR orhigh-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. We provide a large number of solutions for customers in more than 160 countries/regions around the world, and are committed to creating the most suitable solutions for customers. We welcome your inquiry 7/24 hours.

Though long established in the cement industry, penetration to the hard-rock mining industry was slow , and hampered by high maintenance requirements both for wear surfaces in general, and in particular, high wear on the edge of rolls. HPGRs first made inroads into diamond processing where rock fracture along grain lines favored a reduction in diamond breakage during comminution, and in the iron-ore industry. Over the course of the past 20 years. HPGR based circuits have become a circuit commonly evaluated, and there are now many circuits in operation.

The most common HPGRbased 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. In hard-rock metals mining applications, HPGRs are currently in use in tertiary and quaternary crushing applications, as well as in secondary pebble crushing. In many respects, HPGRs replace crushers as a unit operation.

However, from a process standpoint. HPGRs produce a product with substantially more lines for a given P80 than a crushing circuit. In this regard, the size distribution of an HPGR circuit is much more similar to the product of an SAG circuit than a conventional crushing circuit, reducing the amount of pow8217er in the ball-mill circuit required relative to a crushing circuit.

Newmont Mining Companys Boddington gold project followed on the heels of the Cerro Verde project and, after considerable care and study, selected HPGR comminution, with circuit commissioning in 2009 Hart et al 2011. Using Boddington as a reference for comparing an SAG-based circuit to the selected HPGR-based circuit was widely documented in the literature. The project was commissioned with a similar comminution flowsheet to the Cerro Verde and also employing four 2.4 x 1.7-m units.

In summary8217, and relative to an SAG mill primary circuit, HPGRs appear to be most attractive with hard and abrasive ores, and in environments with high power costs. Availabilities are now8217 such that aside from rolls change-outs, which are akin to a mill liner change, the unit rarely controls circuit availability. Overall single-line availabilities comparable to SAG milling can be attained.

Summary In this paper, the performance of a closed circuit HPGR operation was evaluated by the data obtained from six measurements in a cement grinding circuit operating in Turkey. Flowrates of the streams and classifier performance were evaluated after mass balancing. The average specific energy consumption of the HPGR for six measurements was 9.62 kWht for grinding from 17.9 mm to 57 181m.

HPGR roll diameters typically range from 0.5 m to 2.8 m, depending on the supplies, and roll widths vary from 0.2 m to 1.8 m. The aspect ratio of the rolls also varies as a function of manufacturer. Typical HPGR throughput rates range from 20 to 3,000 tph, with installed motor power as high as 3,000 kW per roll. The roll surface is protected with wear-resistant materials, and it has been these that have traditionally stymied HPGR acceptance, but solutions are now in place.
