1. Introduction. Currently, in the primary crushing stage, commonly used crushers include jaw crushers and gyratory crushers. Recently, FL (2022) has introduced an eccentric roll crusher, which has gained favor in the crushing industry due to its high efficiency and energy-saving advantages. They are widely used for primary …
