Process optimization
experience and innovation
Primary gyratory crushers form a critical transition between the mine
or quarry and the plant. Drilling and blasting produce material feed in a
broad range of fragmentation, whether it is iron ore, copper ore, limestone
or any other material. Most large operations depend on gyratory crushers
甲鱼相克的食物to reduce the material to a manageable size suitable for the crushing or
processing plant. As a key link in the process, the crushers must be chon
to meet capacity and performance requirements. Reliability and rvice
support for years to come are equally important. And with a commercial
life of veral decades, the technology should also be suitable for future
expansions, process changes or variations in feed material.
PROJECT EXPERTISE妻子你辛苦了
Investments in primary gyratory crushers are commonly part of bigger
expansion or upgrade projects. Sandvik has the credentials to design,
source, erect and commission the complete process surrounding a
crusher. This applies to turn-key stationary or mi-mobile installations,
including the growing application of in-pit crushing and conveying (IPCC).
PROVEN EXPERIENCE
Sandvik Mining and Construction offers a complete range of primary
gyratory crushers. Although Sandvik has long in-hou experience in the
design and manufacture of gyratory crushers, the CG ries is a result of
a co-operation with EarthTechnica Co., Ltd, Japan, a company owned by
Kawasaki Heavy Industries, Ltd. The mechanical designs of the machines
have been fi ne-tuned over many years and the crushers are well proven
in operations globally. Numerous successful installations have recently
been made throughout Africa, Asia and Australia. Their solid designmas
alone brings an assurance of long life which ts the CG ries apart in the
market.
PERFORMANCE INNOVATION
In traditional gyratory crushers, the hydraulic adjustment of the main
shaft is ud only to compensate for wear. By contrast, Sandvik applies
modern control systems to fi ne-tune throughput and size distribution. A
key benefi t of Sandvik’s renowned cone crushers, the ASRi™ (Automatic
Setting Regulation) system is now applied to all gyratory crushers in the

CG ries. This translates into greater effi ciency and fl exibility –now and
for the future. Having previously been fi tted to more than twenty primary
gyratory crushers, the benefi ts are well established. By combining leading
mechanical designs and control systems, Sandvik brings performance
innovation to gyratory crushing.

DURABILITY
The top bearing in gyratory crushers is subject to unbalanced
extreme loads. Traditionally, this is a high maintenance item
with resulting stoppages in production. The spherical design
of the Sandvik spider bearing has completely eliminated
the point loading causing such problems. The result – no
spherical top bearing has ever required replacement!
The shrink fi t mainshaft sleeve and threaded collar have
eliminated traditional threads prone to fatigue failures
on the mainshaft. Also, the metallic contact between the
upper mantle area and the mainshaft absorbs forces from
crushing big boulders, avoiding damage to the headnut
and mainshaft. Durability by design.
PERFORMANCE
Feed materials, from hard and abrasive to soft and sticky,
behave differently in the crushing chamber. By optimizing the
nip angle and eccentric movement for the actual application,
the capacity, output, energy consumption and wear life can
be optimized for each individual crusher in the CG ries.
A correctly designed crushing chamber minimizes slip-
ping or jumping of the main shaft, even with the hardest
feed material. Performance by design.
SERVICEABILITY
The concave liners, of mangane steel, literally take a
beating. Traditionally, deformation requires trimming
with blow torches as the concaves stretch, with total
replacement as they eventually come loo. Avoid the
costly and unsafe practices. The Sandvik crushers u
cured concaves, which are constrained and lf tightening
between through-bolts and grooves in the shell. Since they
are individually replaced and fastened, properly installed
concaves cannot detach during maintenance. Serviceability
by design.

A hydraulic cylinder adjusts the main shaft and determines
the crusher tting. To utilize the hydraulics beyond wear
compensation, Sandvik employs an intelligent control
system, ASRi™, which lets you fi ne-tune the crusher during
operation. Change the tting with the push of a button –

design.
