Kawasaki Gyratory Crusher
(KG Series)
A Gyratory Crusher with a Crushing Chamber
designed to ensure optimum performance for the
particular application.
Kawasaki’s Gyratory crusher for primary crushing of iron ore, copper ore or other materials has
been designed and built on the basis of extensive crushing and manufacturing technology and
operational experience.
These state-of-the-art range of crushers feature quality and dependability as required for
the primary crushing operation of any major mine or material preparation operation.
In addition to a simple strong structure, the crushing chamber design
is optimised to meet the requirements of the specific crushing
application ranging from the processing of extremely hard and
abrasive material to soft sticky material.
Wet system primary crushing can also be done allowing crushing and scrubbing to happen simultaneously in the primary
crushing stage.
Metallurgical Features and Benefits:
Special attention has been paid to the crushing chamber design to ensure the correct nip, angle and
eccentric movement where it is required. Furthermore, the required discharge setting can be maintained
throughout the useful life of the mantle and concave liners. The result hereof is excellent metallurgical
performance.
The discharge setting is adjusted by the amount of oil in the hydraulic cylinder provided at the bottom of the
main shaft. While adjustment of the discharge setting is easily accomplished by means of this hydraulic
system, it also provides the capability to release uncrushable material fed into the crushing chamber. This
system also enables the crusher to be re-started under load.
Kawasaki Gyratory Crusher
(KG Series)
Mechanical Features
and Benefits:
1.As a result of Kawasaki’s patented
crushing chamber design, which
matches the feed material size distribution, slipping or jumping of the
main shaft rarely occurs, even during
the processing of very hard material.
2. The design of the machine and crushing chamber is such that the required
discharge setting can be maintained
throughout the useful life of the mantle and concave liners.

4.Dust sealing is of the dual system
type, consisting of a dust ring of a
special material and an over-pressure
air system.
7. A discharge set indicator is a standard
feature. Adjustment of the discharge
setting is carried out easily and within
a short time by means of the hydraulic
system.
SPIDER CAP
DUST COVER
Dust protection cover to prevent dust ingress.
SCRAPER AND SEAL
Scraper to prevent dust or mud on main shaft from entering
double seal design with oil seal installed.
3.Mounting of the concave is of a
patented self-tightening design. The
concave liners cannot come loose
during operation and can be replaced
by one row at a time.
6.The seal for the spider bearing has
a scraper on its outside to remove
mud or dust, with an oil seal installed
inside for double seal construction.
The life of the spherical bearing is
thus extended.
SELSYN TRANSDUCER
for shaft position.
SPIDER BEARING
Spherical bearing with high load carrying capacity for longer life.
Inner sleeve design for easier service. (Patent)
LOWER AND UPPER TOP FRAME
Robust upper frame design.
5.A spherical bearing employed as a
spider bearing provides greater load
carrying capacity and extended service life. The inner race of the spherical bearing is of patented sleeve
construction for easier maintenance.

2.Actual capacity may vary according
to characteristics and conditions of
feed material (such as compressive
strength, size, etc).
3.For operations in brackets, consult
with supplier.
