||Gyratory Crushers are a primary crusher used in mining and ore processing
Similar in concept to a jaw crusher:
• Concave surface
The gap is opened and closed.
Material travels downward between the surfaces being crushed more and more until it is small enough to fall out of the gap.
Gyratory crushers are used for primary or secondary crushing.
Crushing is caused by closing the gap between the mantle line mounted on the central vertical spindle and the liners mounted on the main frame of the crusher.
