How Does a Rock Crusher Work? | Sciencing
Gyratory and cone crushers work in pretty much the same way, although they have slightly different designs. The rock falls into the top of a chamber with a spinning grinder at the bottom. As the rock falls down, it is squeezed between the grinder and the walls of the chamber and crushed. As it continues to fall down the chamber, it is ...
Minerals | Free Full-Text | Torque Analysis of a Gyratory …
The ratio k m s in previous research works of gyratory and cone crushers is quite low, which means the smallest particle is close to the c s s. Most of them have k m s < 3, and the maximum value is 7.08, as presented in Table 4. For simulations where BPM was used, the d min is considered as the minimum size of the fraction particles.
