industries, the application of HPGR ranges from coarse grinding, e.g. the grinding of 65mm (2.5") size excess pebbles in AG circulation loops, to final grinding of <100μm material to high Blaine values in the preparation of pellet feed. KHD has a history of successfully installed HPGR units which have demonstrated long term reliability and
Thyssenkrupp and Enter Engineering have signed an Agreement of Intent worth €50 million (US$58.5 million) on building an integrated mining metallurgical complex at Tebinbulak. The HPGR plant will be used to help process up to 60 million tons of iron ore per year, said the companies. The Tebinbulak deposit is located in the Karauzyak district ...
CRITICAL HPGR PARAMETERS. 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.
Outotec's HRC with flanges has been proven to enhance HPGR circuit operation with overall finer product size gradation and the resulting reduction of circulating loads and energy consumption. The flanges enhance the draw-in of material into the roll gap, resulting in a wider operating gap, reducing specific energy consumption and allowing ...
The material is fed to the HPGR by gravity and dragged into a compression zone between the rolls. The nip angle (α) represents the point in which the roller force starts acting on the material, thus starting the packed bed compression.The nip angle is dependent on the roller diameter and several material properties such as particle size and shape, moisture, elastic properties, and …
HPGR feed increases and hence, results in a finer product. Because the total throughput of the grinding systems remains equal the size of the HPGR has to be increased to be able to handle both fresh feed and recycle. The fineness along the roll axis follows a certain gradient according to Figure 9. Reasons for
HPGR application is also being considered for bauxites or alumina, given the potential benefits of a high unit capacity (up to 2500 TPH …
High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.

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 high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the leaching liquid. Also, flotation efficiency is further enhanced through ...

HPGR—FAQ There are several unusual terms that seem predomi-nantly to relate only to HPGRs—what do they all mean? These terms relate to the performance of the HPGR and were formulated largely to assist in the process of scale-up from laboratory or pilot tests to full-scale machines. Specific press force (N/mm²)—the applied force divided
More energy-efficient and longer-lasting rolls. The HPGR Pro fulfills the most demanding requirements for economical operation – above all through enhanced energy efficiency, improved product quality, and up to 30 % longer-lasting rolls due to reduced wear and tear.
This forces the rocks against each other and compresses the feed's density to 80% of its solid volume, exceeding its compressive strength with equal pressure being applied to particles of all sizes. Why HPGR? Decrease your energy consumption by up to 40% Reduce recirculation and wear within your crushing circuits
If the HPGR is open at the axial ends of rolls then particles are relatively free to move which can be expected to limit the development of high pressures and therefore the breakage performance. In this HPGR design, cheek plates are included which constrain the axial movement of particles near the ends of the rolls. These are shown in Fig. 2 ...
