Secondary Jaw Crusher

Secondary Jaw Crusher and Functions

Secondary jaw crushers are crushing equipment used in the second stage of crushing plants, designed to further reduce materials pre-crushed by primary crushers.

Secondary jaw crushers receive material that has been pre-crushed by primary crushers and reduce it to even smaller sizes. These crushers work with the same operating principle as primary jaw crushers, but are designed for finer crushing and higher production capacities. They are an important part of multi-stage crushing systems.

Operating Principle

Secondary jaw crushers work with the same compression principle as primary crushers. The movable jaw moves with an eccentric shaft and crushes the material between the fixed and movable jaws. However, secondary crushers have a smaller feed size and can produce finer output compared to primary crushers.

Main Components

Fixed Jaw: The stationary crushing surface made of wear-resistant materials.
Movable Jaw: The jaw that moves back and forth and performs the crushing action.
Eccentric Shaft: The shaft that provides the reciprocating motion.
Flywheel: The component that stores kinetic energy for smooth operation.
Toggle Plates: Safety components that protect against overload.
Frame: The robust structure that houses all components.
