| Jaw 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.
