To accommodate this uneven pressure, Enduron ® High Pressure Grinding Rolls utilise a unique springloaded lateral wall which reduces the edge effect (maintaining a gap of as little as 1 mm) and is specifically designed to facilitate roll skew. As shown above, an uneven feed will lead to high pressure on one side and not enough on the other.
High Pressure Grinding Rollers (HPGR) are comminution equipment that are primarily operated in cement and limestone plants. However, recently HPGR are also being used in mineral, iron ore and diamond treatment plants over the conventional technologies by semi .
The technology's working principle is that two counterrotating 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 grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface.
