A time dynamic model of a high pressure grinding rolls crusher
The crusher was then retrofitted with hydraulic cylinders to increase the pressure between the rollers. This was the predecessor to the high-pressure grinding rolls (HPGR) crusher, which became popular in Europe for applications in the cement industry. The introduction of the HPGR in minerals processing sparked at the beginning …

Crusher
The cone crusher is a modified gyratory crusher. The essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone (Figure 8.2). Power is transmitted from the source to the countershaft to a V-belt or direct drive.
