The HPGR model, combined with powerful computers and larger sample masses for simulation, can be used as a procedure to size and select an industrial HPGR unit and to analyze the equipment behavior under various operating conditions and feed characteristics. iii Preface This project work is a part of the UBC HPGR research program that took ...
HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming increasingly popular. The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific ...
Cerro Verde actual data shows that the HPGR circuit energy consumption was 3 kWh/t less than the SAG/Ball mill circuit that was considered in the trade off studies. The initial trade off studies were expecting to have 4.2 kWH/t of less energy consumption. (unknown) 7 years ago.
Resumen. La actual práctica de la industria para la evaluación y el dimensionamiento de las prensas de rodillos de alta presión (HPGR, por sus siglas en inglés) se basa en la realización de una serie de pruebas usando máquinas a escala piloto con diámetros de rodillos de 700 mm a 1.000 mm.

For grinding to a P80 of 160 μm, the HPGR-ball mill circuit required 21% less energy than the SABC circuit. The main savings result from the lower energy required by the HPGR as compared to the SAG mill. However, an additional secondary crusher and conveyer system were required to facilitate the HPGR circuit.

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 is typically used in a third-stage or fourth-stage crushing application ahead of grinding. You could always try to build a circuit doing 45 µm classification, but I suspect your circulating load would be overwhelming. Most HPGR applications in hard rock mining achieve 3000 µm to 7000 µm product
2. Description of a HPGR A HPGR is principally a horizontally mounted double-roll mill, equipped with hydraulic pistons on one side, pressing against the floating roll - the other roll being fixed in the frame. The main components of the machine are of course the rolls, the bearings, frame, pressure beams, hydrau-
