CRUSHER :- |
| |
|
The
working principal of Jaw Crusher is based on modern design "CRUCHING
WITHOUT RUBBING" The machine consists, two Jaws, one fixed
and the other moving . The opening between them is smaller at
the bottom and wider at the top. The pitman moving on an eccentric
shaft on bearing, swing lever (Moving Jaw) swing on center pin.
he Rock held in between two Jaws and crushed by mechanical pressure.
|
|
|
CRUSHER FRAME :- Crusher Frame is made of high welding.
As a welding structure, it has been designed with every care
so as to ensure that it is capable of resistant to bending stress
even when crushing materials of extremely hard.
|
|
JAW STOCK :- Jaw Stock is also completely welded and
has renewable bushes, Particular importance has been given to
jaw Stock of a design resistant to bending stresses. All jaw
stocks are provided with a renewable steel Alloy or manganese
steel toggle grooves.
|
| |
|
Pitman
is made of high quality steel plates and carefully stress
relived after welding. The Pitman is fitted with two renewable
steel Alloy or manganese steel toggle grooves housings for the
bearings are accurately bored and faced to gauge.
|
|
Eccentric
Shaft is machined out 'of Alloy Steel Fitted with anti-friction
bearings and is housed in pitman and dust proof housing.
|
| |
|
|
|
| |
|
Anti-Friction
Bearings are heavy duty double row self-aligned roller-bearings
mounted in the frame and pitman are properly protected against
the ingress of dust and any foreign matter by carefully machined
labyrinth seals.
|
|
Crushing
Jaws are castings of austenitic manganese steel conforming to
IS 276 grade I & II. The real faces of the crushing jaws
are levelled by surface grinding in order to ensure that they
fit snugly on the crusher frame and jaw stock. The crushing
jaws are reversible to ensure uniform wear and tear of grooves.

|
The
Wedge Setting is accessible and permits easy and reliable setting
of the width of the gap. The wedge block is fitted with a renewable
Alloy steel or manganese steel Toggle bearings.
|
|
Toggle
Plates are of special quality hard iron with chilled ends.
|
|
Side
Plates are of special quality manganese steel castings.
|
|
Lubrication
of bearings is by grease gun through suitable nipples.
|
|
Fly
Wheels are made of good quality cast iron. Robust design, machined
and balanced, suitable for either flat or vee belt drive.
