JC Series Jaw Crusher
Model No.: | JC |
Place of Origin: | China |
Brand: | Sanme |
Product Description
As a new generation product of our company, JC Series jaw crusher it is based on years' expertise in designing and conception and absorbs top crushing technology and research fruit in the world. It's birth thanks to finite element analysis method.
Wroking Principle:
The motor drives belt and pulley. The movable jaw swings up and down
before and after through the eccentric shaft. When the movable pushes
the movable jaw plate to the fixed jaw plate, the material is crushed or
split into pieces. When the movable jaw and movable jaw plate springs
back in the effect of eccentric shaft, the material previously have been
crushed discharges from the discharge opening of the lower part. With
the motor continuously rotating, the movable jaw breaks and discharges
material periodically to achieve mass production.
Compared with traditional jaw crusher, JC series jaw crusher pays more
attention on details in the process of design and manufacture. It uses
high-strength materials, advanced manufacturing technology, which
contributes to the stronger structure, higher reliability, larger
crushing ratio, higher productivity, lower cost.
Features and benefits:
1.Robust structure
There are two types of machine frame: welded model and assembled
model. The former is for small and middle size, and the latter is for
big size.
The welded type adopts large arc fillet and low stress welding
method, greatly reduces the concentration stress which ensures rack
equal strength in all directions, high impact resistance, even force,
low failure rate.
Assembled uses advanced modularization and non-welded frame
structure design of high fatigue strength and high reliability.
Meanwhile machine assembly design makes transportation, and installation
more convenient, especially suitable for installation in narrow and
small places like undermine and high altitude mining.
2.Optimized cavity structure
Symmetrical V formed design, toggle of large obliquity, long stroke,
reasonable rotor speed, allow larger materiel block in feeding, higher
productivity, homogeneous output granule, less attrition for jaw plate.
3.The whole set of heavy movable jaw plate is durable.
The whole set of heavy movable jaw plate integrates forged heavy
eccentric shaft, high quality bearing of heavy loading, the design of
movable jaw plate optimized by finite element analysis. These features
assure the stroke resistance and stability. Labyrinth seal and
centralized lubricating system prevent the greese of bearing not to be
contaminated, and assure the easy lubrication which results in longer
function and more stability.
4.Protective planch of movable jaw plate
Heavy protective planch installed above the movable jaw plate protects
internal bearing from damage caused by material falling down in feeding
moment.
5.One piece cast of bearing seat
One piece cast of bearing seat assures good match with frame, and avoids
unnecessary radio direction pression for bearing in fastening process
which occurs usually to composed bearing seat. Therefore, bearing can
function more stably.
6.Fast and easy adjustment of output granularity
Jaw PE,PEX jaw crusher adopt mechanic or hydraulic device to adjust
discharge opening. Compared with shim, adjustment by double block is
simpler, saver, faster, and reduces downtime.
7.Installation integrating motor & crusher
Integrative installation of motor chassis and crusher frame not only
saves installation space of jaw crusher but also reduces the length of
Vee belt. Thanks to synchronous movement of crusher frame, motor chassis
and motor. Adjustable motor chassis can realize the adjustment of
Vee-belt's tensile force to make the Vee-belt more durable.
8.Shock absorber installation
The crusher is fixed by the device of special rubber shock absorber,
which absorbs effectively the its vibration at the peak point and
meanwhile, allows crusher to displace in vertical and horizontal
direction. In this way, the shock to foundation would be reduced.
