Granite And Limestone Crushing Jaw Crusher Machine Crushing Uniform
Particle Size
Jaw Crusher: The Primary Workhorse for Hard Rock Crushing. A jaw crusher is a robust, heavy-duty machine used as the primary
crusher in most crushing circuits. Its powerful design is
engineered to handle the largest and hardest rocks and ores,
reducing them to a size suitable for secondary crushing. It's the
cornerstone of mining, quarrying, and aggregate production
operations worldwide.
How It Works: The Power of Compression
The working principle of a jaw crusher is straightforward and
highly effective, based on compressive force:
Feed Material: Large rocks are fed into the top of the crushing chamber from a
vibrating feeder.
Fixed & Movable Jaws: The chamber consists of two jaw dies: a fixed jaw and a movable jaw.
Reciprocating Motion: The movable jaw moves in an elliptical orbit, driven by an
eccentric shaft. It periodically presses the rock against the fixed
jaw.
Crushing Action: The rock is crushed by the immense compressive force generated
between the two jaw plates.
Gravity Discharge: The crushed material becomes smaller and moves down the chamber
by gravity until it is small enough to escape through the opening
at the bottom (the discharge gap).
