TECHNICAL NOTES 5 CRUSHERS
d1 and d2 are parameters that are characteristic of the crusher. They are determined primarily by the setting of the crusher. Data from operating crusher machines indicate that both d1 and d2 are proportional to the closed side setting. d1 is the smallest size particle that can be retained in the crushing zone during the opening phase of the cycle.

Primary 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.
