TYPES OF MATERIAL HANDLED
Ports – Ship Loading & Unloading of Materials
Steel Plants – Ore, Coal, Limestone etc.
Cement Plants – Limestone, gypsum, clinkers etc
Power Plant – Coal
Mines – Excavation, Mining & Handling of Minerals & Materials
Food Industry – Grains ( pneumatic conveying)

CONCEPT OF COAL HANDLING
Receipt of Coal
Trucks/dumpers Open Wagons Box N, Box C etc. Bottom discharge wagons Ships Long belt conveyors ( From Ports & Mines)
Unloading
Truck tipplers / Self Unloading dumpers Wagon tipplers / Manual unloading by opening of side doors Track Hopper Ship unloaders / Geared ship / Self unloading ships Surge hopper and feeders
CONCEPT OF COAL HANDLING
Conveying
Feeders (Apron, Vibrating, Belt, Paddle Feeders) Bucket Elevators Steep angle conveyors Troughed Belt conveyors (unidirectional / Reversible) Shuttle Conveyors Pipe Conveyors Chutes & Skirt boards, Hoppers Flap gates, Rod gates, Rack & Pinion gates, Flow dividers, Shuttle heads. Magnetic Separators ( Inline / Cross Belt), Suspended Magnet Belt Weighs Metal Detectors Chute Block Switches Sampling system
CONCEPT OF COAL HANDLING
Crushers
– Ring Granulators
– Double / Four Roll crusher
– Hammer mill
– Rotary Breakers
– Feeder Breakers
Screens
– Vibrating Screens
– Vibrating Grizzly Feeder
– Roller Screen
– Wobbler Screen
– Flip Flop Screen
– Banana Screen

COAL PRODUCTION IN INDIA
1900 – 6.12 MT
1920 – 18 MT
1942 – 29 MT
1946 – 30 MT
33 MT – Beg. Of 1St 5 year plan
Now approx. 400 MT/annum

UN LOADING FACILITY - CHP
• 1950’s-60’s – Plant 37 MW max emerged
Unloading – Over ground hopper (Truck tippling)
• 1960’s-70’s – Plant of 120 MW max emerged
Unloading – Wagon tippler complex(12-15 Tips/H)
• 1970’s-80’s – Plant of 210 MW max came with pit head concept
Unloading – Through Track hopper, wagon owned by power plant
• Early 90’s Railways started supplying Wagons
Opted to have both Track hopper & Wagon tippler (20 tips/hr)
• After 2000 – Higher Capacity plants started
Wagon tippler (20 – 25 tips/hr) & Track hopper of higher rate emerged
• Recently government is going towards Ultra mega Power plant (4000 MW)
Pit head or Port based unloading
POWER GENERATION IN MAIN STATES
Maharashtra – 14000 MW
Gujarat – 9500 MW
A.P – 8100 MW
Tamil Nadu & U.P - 7000 MW
W.B – 6500 MW
Bihar – 1900 MW

CONCEPT OF PORT
Port is basically a Service Provider
Comprises Ship Loader & Un loader Conveyor Stacker, Reclaimer or Stacker cum Reclaimer Wagon Loaders, Flood loading system.
Lower loading & unloading rates leads high penalty Unloading & loading rate is typically higher in ports
