I have experienced many problems due abnormal power draw behavior of the electric motor in a primary gyratory crusher in iron ore crushing, especially when the service life of the first row concave comes to an end. I suspect that the current eccentric throw of the mainshaft (52mm) is higher than is really necessary.

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.

The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesn't stay in the center of the chamber – it sweeps around moving closer and further away from the concave. This is what creates the crushing action. At a ...

However, as the eccentric angle and the pivot point control the degree of eccentric motion at any height in the crusher, the height of the pivot point is a key design decision. A cone crusher with a feed distributor (as shown in Fig. 2) often has the pivot point close to the center of the feed spreader plate.

A parameter that is difficult to change but is important for the operation of the jaw crusher is the throw. Fig. 16 shows the variation of power draw of the crusher under different CSS, when the throw is gradually increased. It can be observed that the power required to drive the crusher increases with increasing eccentric throw.
