About 500 high-pressure grinding rolls (HPGRs) are in use in the cement industry for the pre-treatment of ball mill feed. This technology enhances the capacity of the downstream ball mill and reduces the total energy consumption of the grinding process by up to 50 %.
Through historical co-operation with KHD in the manufacture of High Pressure Grinding Rolls (HPGR) CITIC HIC now designs and manufactures a full range of HPGR’s to suit the cement and mineral processing industries. With over 170 units sold CITIC HIC has the experience in supplied world class HPGR’s to the industry.
The High-Pressure Grinding Rolls technology is currently the most efficient method of crushing in hard ore industry, but the issue still needs extensive investigations in order to increase the...
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. Main features of the HRC™ HPGR are: Patented anti-skewing Arch-frame
High Pressure Grinding KHD Humboldt Wedag Roller Presses. With our Roller Presses, the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable, closed machine frame. A key feature is the mounting of the rollers in oil-lubricated cylindrical roller …
Our HPGR Rolls utilizes the principle of high pressure inter particle comminution to grind various types of ore, industrial minerals, or clinker for cement production. Using our proprietary edge, stud and roll design and unique state of-the-art wear technology, a CSP HPGR Roll consumes less energy resulting in reduced operational costs and exceptional long term reliability.
High pressure grinding rolls (HPGRs), also known as roller presses, are rapidly gaining acceptance in hard-rock processing, primarily due to their energy efficiency when reducing mineral ore to fragments.
The high-pressure interparticle comminu-tion in the POLYCOM® is based on the following principle: Brittle material particles are fed to the POLYCOM® through a feed bin. The grinding elements are two counter-rotating rolls, between which the material is crushed. One roll is designed as a fixed roll and the other one as a floating roll.
