MOLINOS HPGR - Encuentro Metalurgia

HISTORIA DE LOS HPGR • El origen de la tecnología HPGR, se remonta a los inicios del siglo XX, donde se utilizó en la briquetización de carbón. • En el año 1985 la tecnología fue introducida en la industria del cemento. Actualmente, éste es el sector industrial que utiliza mayor cantidad de molinos HPGR en el mundo.

High pressure grinding rolls (HPGR) - Outotec

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.

Perfecting Hard-Rock High Pressure Grinding Performance - E & MJ

The uptake of HPGR technology by metallic mineral processors has involved a number of suppliers but primarily KHD Humboldt Wedag and Polysius for the HPGR machines and ABB for the drive systems. Normally, it is the HPGR supplier's prerogative to choose the drive supplier; the end user normally buys the HPGR with the drive systems included.

A methodology to predict the HPGR operational gap by

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 …
