| Feed Hopper: The Feed hopper has a nominal volume of 7m3 and
the hopper has hydraulic foldable sidewalls, for ease
of transportation. The hydraulic system enables the
operator to control the feed rate, by changing the
speed of the vibration motor. This feature is especially
useful in order to obtain maximum output from the
whole installation; also an ultrasonic level system will
automatically start & stop of feeder depending on the
level of material above the crusher.

Feeder:
The feeder is a vibrating grizzly unit (4.2m x 1.04m) including 1600 mm long grizzly section.
This feeder has been specially designed for operation with coarse material and high impact load. The feeder has cassette type grizzly bars and is fitted with Hardox 400 liner plates. This feeder has two unbalanced shafts located under the vibrating structure. They rotate in opposite directions, resulting in straight-line motion due to the self-synchronizing effect. The vibrators are oil lubricated and have adjustable counterweights.

Swing and Stationary Jaw Plates:
These are cast of austenitic manganese steel, with various
profiles, specific for each material to be crushed. The
dimensions are the same for the stationary and the moving
jaw plates. This makes it possible to freely change the
position of the jaw plates. The jaw plates are fixed to the
crusher's swing jaw and frame by means of wedges and tie
bars.
Swing Jaw:
This is a heavily ribbed one piece steel casting. Its eccentric
movement (throw) causes the jaw plates to crush the material
as it is forced down trough the crushing chamber.
Shaft:
The eccentric shaft for the J11 crushers
is a low-alloy steel
forging. The
eccentric part of the shaft provides the
throw
of the swing jaw. Precision
machined and of ample diameter, it
ensures that the bearings have a long
useful service life. For
extra heavy
duty service the roller bearings are of
the
self-aligning type, protected by
labyrinth seals and
are grease lubricated.
Cheek Plates (Side Liners):
These plates are made of austenitic manganese steel, and
protect the frame against abrasive wear in the region of the
crushing chamber. They are bolted to the crusher side plates.
Note that the left and right hand cheek plates are identical,
and thus reduce the number of different spare part items that
have to be stocked. |
Toggle Plate and Seat:
This is a nodular iron casting. Its ends rest in the "lubrication-free rolling-contact" toggle seats, thus maintaining the lower part of the swing jaw in the correct position. It takes up most of the compression force generated in the crushing chamber by the swinging movement of the swing jaw. The wear parts of the toggle seat, which support the toggle plate, are made of medium carbon steel, and machined in order to ensure the correct dry rolling contact.
Setting Adjustment:
Fully hydraulic adjustment, wedge type.
1 ½” – 5” CSS
3” – 7” CSS
The 2 different CCS setting ranges are
obtained by changing toggle plates.
Flywheels:
Made of cast steel, their geometry provides a high moment of inertia, thus reducing the dynamic load variations transmitted to the motor. They are fixed to the shaft in a manner that facilitates disassembly, even after a long time in service. Each flywheel is also fitted, with a counter-weight that balances the crusher in the best way possible, reducing horizontal forces to a minimum.
Crusher Load Sensing:
a) Ultrasonic level system, above crusher, controls the feed from the feeder into the crusher to obtain constant material flow and maximum output.
b) Speed sensor on drive flywheel, observes
crusher speed, max 270 rpm and min 235 rpm,
to control crusher feed and avoid overloading of
crusher unit.

Conveyor & Crusher Outlet:
The
discharge

conveyor
is
with
the
tail

fitted
underneath
the
jaw

and
crusher
by-pass

To
give

is
automatically
lowered

depending
on
if
the

Frame:
Rigid one piece welded construction consisting of steel plates and cast carbon steel parts, heat-treated after welding (for internal stress relief), and then precision machined. The simultaneous use of both plate and castings makes it possible to position the weldments in regions of lower mechanical stress. This feature considerably increases the fatigue resistance of the welded frame assembly. |
