A jaw crushing machine is a type of equipment used to break down hard materials, such as rocks, minerals, and ores. It consists of a fixed jaw plate and a movable jaw plate that is positioned in a V-shaped configuration. As the movable jaw plate moves back and forth, it crushes the material against the fixed jaw plate.

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 …
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …
