An iron ore company milled ore at the rate of 150 t/h in a ball mill in closed circuit with a classifier.

Influence of Two Mass Variables on Inertia Cone Crusher …
Furthermore, at the same industrial scale, the mass of the inertia cone crusher is much heavier than other cone crushers, such as hydraulic crushers and spring crushers. The reason is that the eccentric vibrator leads to the violent vibration of the crusher and the increase of energy consumption. Znamenskll et al. [16], regarding the dynamic ...

While cone crushers are usually supported at the base, gyratory crushers are suspended. Impact crushers, sometimes called "hammer crushers," use mass and velocity to break up pieces with a blow bar or hammer that strikes a stationary plate. When the rock hits the plate or anvil, it breaks on natural stress lines to create a uniform product.
