Roller Presses for Briquetting, Compaction and Grinding Köppern roller presses are centered around two counterrotating rollers, supported in the frame by spherical, selfaligning roller bearings In addition to radial loads, the bearings are able to accommodate axial loads acting in both directions, making them insensitive to shaftskewingThe comminution process of High Pressure Grinding Rolls (HPGR) was discovered in the 1980s by the research work of the German Professor Schönert Its main advantage is the high energy efficiency in comparison to ball mill grinding which has been the benchmark process in the cement industry by then (Schönert, 1988)Quantification of HPGR energy efficiency effects on downstream grinding
During recent years a worldwide trend towards comminution installations using High Pressure Grinding Rolls (HPGR) has been established [1] This comminution practice was made famous in the 1980s by the research work of the German Professor Schönert The technology has its foundations much deeper in the past [2]High Pressure Grinding Rolls have been used for the grinding of diamond and iron ores since about 1988 There are now about 40 machines operating worldwide in these industries This number is still small in comparison to the > 450 machines employed in the cement and raw materials industryHigh Pressure Grinding Rolls for Minerals AusIMM
compaction applications With the introduction of High Pressure Grinding Rolls (HPGRs) in the 1980s, Köppern successfully expanded into the cement industry, building a strong position through innovative press designs such as the C ‑ Frame® and Hinged‑Frame as well as the unique HEXADUR® wear protection systemThe MinasRio Project that is being implemented by Anglo Ferrous Brazil, foresees the use of HPGR (High Pressure Grinding Rolls) KHD Humboldt Wedag AG e Koppern, todas sediadas na Alemanha 3 Objetivos Os principais objetivos desse estudo foram: Validar a aplicação das prensas de rolos ao tipo de minérioAplicação de prensas de rolos em minério de ferro SciELO
