INTRODUCTION
 This plant is located in DALLI RAJHARA, BALOD
(CHHATISGARH).
 This plant is Eleven - times winner of Prime Minister’s Trophy for
best Integrated Steel Plant in the country, Bhilai Steel Plant (BSP).
 This plant is India's largest producer of rails and heavy steel plates
and major producer of structural, TMT bars and rods.
 The Dalli rajhara plant is also called home of iron ore captive mines
for this Bhilai Steel Plant.
 Iron ore mined from the area are hematite and magnetite variety.

Machine and vehicle
SHOVEL (BE1000-10)
 It is a hydraulic excavator
 it is used to excavate the materials
and loading it to the dumpers
 It's bucket capacities is 3.1-5.55
cu. meter and 4.5-7.0 cu. meter.
 ENGINE : 4 stroke, Six cylinders
diesel engine of 170 mm bore x
170 mm stroke .

5.
Crawler Dozer
 Crawler dozers are continuous
tracked machines fitted with
front-mounted blades to move or
push large quantities of material
such as soil, sand and rubble.
 Attached to the back of a crawler
dozer is a ripper to break and
loosen compacted materials.
 Crawler dozers have engines
from 45 to over 700 horsepower.
 6 inline, Diesel 4 stroke, water
cooled, turbo charged

6.
Dumper (BH60M)
 It is a vehicle designed for
carrying bulk materials
 its capacity is 60 tons
 It is used to shift material from
quarry to crushing plant.
 Maximum payload 54,500 kg

7.
Crushing and
Conveying facility
 A crusher is a machine designed to reduce
large rocks into smaller rocks, gravel, sand
or rock dust
 The degree to which material is reduced
through stages of primary and secondary
crushing can depend on the type of material
Bunker
 Bunker is basically a storage unit where we
dump the extracted raw iron it.
 This plant contain three bunkers first one
main bunker, other is new and old bunker.
 The capacity of one bunker is 2100 tones
and other both bunkers are 750 tonnes.

8.
Conveyor Belts

9.
Gyratory crushers
 Gyratory crushers are characterized by a
gyrating mantle mounted within a deep bowl.
 Gyratory crushers provide continuous crushing
action and are used for both primary and
secondary crushing of hard, tough, abrasive
rock.
 This produces a higher crushing capacity than
others. Gyratory crushers also tend to be easier
to operate.

10.
Jaw Crusher
(Primary crusher)
 From the canveyor iron ore directly
fall into the jaw crusher.
 The jaw crushers in Rajhara plant is
having a capacity of 750T/ hr.
 The basic details of jaw crusher :
Feed Input size is– 0 - 1200mm .
Crushed output size is - 0 to
220mm .

11.
Cone crusher
(Secondary crusher)
 Secondary crushing accepts the material
from the primary crushing stage i.e jaw
crusher and reduces it even further.
 The output of jaw crusher conveying
through the conveyor, the ore is allowed
to feed cone crusher.
 The baic details of cone crusher is: feed
input size- 0 to 220mm. Crushed output
size - 0 to 90mm . Capacity of cone
crusher - 1000T / hr

12.
Electromechanical
vibrator screens
 For screening of crushed ore there are total 7
vibrator screens are available .
 The output of cone crusher is conveyed through
conveyor2 and finally the crushed ore is feed
into mid bunker of capacity 600 tonne
 The screens of these vibrator screens are
slightly inclined or nearly horizontal , because
of which it requires less head room than
inclined screens
 The accuracy of particle sizing on horizontal
screens is superior to that on inclined screens
 Horizontal screens are used in sizing
applications where screening efficiency is
critical

13.
Apron feeder
 The apron feeder is used for handling
course ore especially jaw crusher
feed
 It is ruggedly constructed , consisting
of a series of high carbon or
manganese steel pans, bolted to
strands of heavy duty chain ,which
nun on steel spockets
 In Rajhara C.S.P. the width of the
apron feeder is usually 6 feet

14.
Diesel engine
Diesel engine, any internal
combustion engine in which
air is compressed to a
sufficiently high temperature
to ignite diesel fuel.
It converts the chemical
energy stored in the fuel into
mechanical energy

15.
Four stroke diesel engine
 Intake: Air (light blue) is drawn into the
cylinder through the open green air inlet
valve on the right as the piston moves down.
 Compression: The inlet valve closes, the
piston moves up, and compresses the air
mixture, heating it up. Fuel (dark blue) is
injected into the hot gas through the central
fuel injection valve and spontaneously
ignites. Unlike with a gas engine, no
sparking plug is needed to make this happen.
 Power: As the air-fuel mixture ignites and
burns, it pushes the piston down, driving the
crankshaft (red wheel at bottom) that sends
power to the wheels.
 Exhaust: The green outlet valve on the left
opens to let out the exhaust gases, pushed out
by the returning piston.

Important
components
1. Fuel system
2. Lubrication system
3. Cooling system
 Fuel system
In an engine, fuel reaches the cylinder bore
through the following path:
Fuel tank -> Water separator -> Feed pump ->
Filter -> Injection pump -> Injector nozzle ->
Cylinder

17.
 Lubrication system
The engine lubrication system is to distribute oil to the moving parts
to reduce friction between surfaces.
Purposes of lubrication include
i. Reduces the wear and prevents seizure of rubbing surfaces
ii. Reduces the power needed to overcome frictional resistance
 Cooling system
 To avoid excess heat and to protect engine components including
cylinders, cylinder head, pistons, and valves
 There are two types of cooling:
1) Air Cooling 2) Water Cooling

18.
Conclusion
 The Vocational training designed by IOC, Dalli
Rajhara, Bhilai Steel Plant (SAIL). Gave us a
pronounced opportunity to gain industrial
experience and exposure to the practical world.
 SAIL is an integrated mining steel plant which
deals with extraction, processing (beneficiation)
and manufacturing.
 The the ore is collected in the field is sent to
processing plant To be processed as per
specification of the clients.
 During this training we learnt how to categorize
ore.
 This vocational training has given us new
insights and motivation to pursue a career In
steel industry.
