C jaw crusher and basic concepts
The jaw crusher is a compression
type crusher. Feed material is
crushed between fixed and mov-
able jaw dies. Large particles are
crushed in a single layer, referred
to as single-layer crushing.
Smaller particles are crushed rock
on rock, referred to as multi-layer
crushing.
Feed opening
Feed opening (depth of the cavity) defines
the maximum feed size of the crusher. In the
C jaw crusher, the feed opening is measured
from the top of the tooth of the fixed jaw to
the bottom of the tooth of the movable jaw
in a straight line perpendicular to the center
line of the crushing cavity.
The maximum feed size is approximately
80% of the feed opening.

Open side setting (OSS)
The open side setting is measured when the
crusher is at rest. The setting is measured
either top to top, or bottom to top, depend-
ing on the tooth profile of the jaw dies.
Closed side setting (CSS)
The closed side setting can be calculated by
deducting the stroke from the OSS. CSS is
the most important crusher parameter since
it defines the maximum product size and
has significant bearing on capacity, product
gradation, power draw, and wear. Check the
instruction manual for the permitted mini-
mum CSS.
