Jaw crusher AAC Block Plant Machinery
The JC series jaw crusher machine is a new type of jaw crusher with
optimized and developed design on structure, material selection,
manufacture process and assembly, which is based on absorbing the
international advanced technology and applying our company's
decades design concept and technology of jaw crusher. With the
feature of smart structure and excellent performance, the machine
is suitable for crushing all kinds of hard and abrasive rock and
mineral ore. In order to meet the needs of different working
conditions from the customers, this machine can apply modular bolt
connecting frame without welding.
There are two types of frame for JC Jaw Crusher: welded frame and
modular bolt connecting frame. Generally we apply the welded frame
for the small and medium-sized jaw crusher and the modular bolt
connecting frame for the large-sized jaw crusher. The welding
method for the welded frame greatly reduces the stress
concentration to ensure the equal strength of the frame in
different directions. They have the features of impact resistance,
even force and low failure rate, etc. The modular bolt connecting
frame has the features of fatigue strength and high reliability.
The non-welded method for the modular bolt connecting frame is very
convenient for transportation and installation, especially suitable
for the underground mine, high altitude mine and other places which
are narrow or difficult for transportation.
OPTIMAL DESIGN OF CRUSHING CHAMBER:
Applying the V-type symmetrical design of crushing chamber, the
actual width of the feeding opening is consistent with its nominal
width. Also with the deep crushing chamer, tight nip angle and long
stroke, the machine has lower energy consumption and better
processing capacity and crushing performance.
SWING JAW ASSEMBLY:
The swing jaw assembly consists of forged eccentric shaft,
high-duty rolling bearings and the swing jaw optimized by FEM
analysis, which ensure the impact resistance and stability of swing
jaw assembly. By using the labyrinth seal and centrailized
lubrication system, there ensure no pollution to the bearing grease
and convenient lubrication, also ensure long operating time and
PROTECTOR PLATE OF SWING JAW:
The protector plate installed on the swing jaw reduces the impact
force from materials, which effectively protect the swing jaw and
QUICK AND CONVENIENT CSS ADJUSTMENT:
The JC Series Jaw Crusher applies mechanical or hydraulic discharge
asjusting device for CSS. Compared with gasket adjustment, its
double wedge adjustment is simple, safe and fast. It can also
reduce the downtime.
The special bearing design ensures the big loading capacity, long
service life and reliable operating.
ROD SPRING OR HYDRAULIC CYLINDER:
Eigher the hydraulic cylinder or rod spring will be used for swing
jaw tension device. The rod spring applies advanced friction
reducing devices which can make easy and qucik adjustment.
INTEGRAL BEARING HOUSE:
The integral casting bearing structure ensures the perfect match
with the main frame, which avoids the unnecessary radial load to
the bearings during the fastening process of integral bearing
house. This makes bearing running more smoothly.
INTEGRATED MOTOR DESIGN:
The integrated design of the motor base together with the main
frame not only saves the installation space of jaw crusher, but
also reduce the length of the V-belt. As a result of synchronized
motion of the frame, motor base and motor, adjustable motor base
realize V-belt tension adjustment, increase the life time of the
RUBBER DAMPING DEVICE:
The special rubber damping device effectively absorbs the equipment
vibration. Meanwhile it allows crusher vertical and longitudinal
displacement, which reduces the impact to the foundation base.
