THE ENTIRE COAL HANDLING SYSTEM DIVIDED IN THREE SECTION. 1.CHP-1 situated inside plant boundary, capacity 1500 TPH
2. CHP -2 situated mine end, capacity 1000 TPH
3. CHP-3 Cross country conveyor which collect crushed coal from CHP Mine end at TP-5 and discharge the same at TP-3 of CHP inside plant, capacity 1500 TPH
DUMPER UNLOADING HOPPER DUMPER UNLOADING HOPPER RECEIVE COAL FROM OPEN COST COALMINES, TRANSPORTED BY TRUCKS AND WILL BE UNLOADED INTO HOPPER AMONG THREE SIDE AT A TIME. DEVIDED IN TWO SECTION EACH CAPACITY IS AROUND 120 MT.SIX DUMPER CAN BE DUMPED INTO HOPPER AT A TIME.MAXIMUM COAL SIZE 1000 MM.
CHAIN FEEDER- 2 NOS A conveyor comprising one or two endless linked chains with crossbars or flights at intervals to move the coal or mineral. The loaded side of the conveyor runs in a metal trough, while the empty side returns along guides underneath. The material is transported on the conveyor partly by riding on the chain and f lights and partly by being scraped along in the trough. MAKE: SWETHA ENGG TYPE: FLIGHT BAR TYPE CF-1/CF-2 CAPACITY: 1000 TPH
ABON SIZER Low Speed Sizing Technology is the employment of a combination of high torque / low roll speeds and tooth profiles to arrive at specified end product sizes with a minimum of fines production. ADVANTAGE: ROM feed size up to 1500 mm (60”) Capabilities in excess of 10,000 mtph Minimal fines creation Insensitive to clay and sticky materials Pre-scalping of undersize not required Exceptionally low headroom requirements Simple infrastructure requirements due to minimal dynamic loads placed on the supports and structure Ability to start up under a full load Long wear life of consumable components due to positive bite and minimal feed slip. TYPE & SIEZE: LOW SPEED SIZER/6492 X 2884 X 1100 MM MAKE: ABON CAPACITY :1000 TPH MANUFACTURER:ABON ENGG
COAL CRUSHER
Ring granulator crusher having nos. of ring hammers mounted to rotor disc in a suspension.Due to centrifugal action coal is being crushed between wear plate and hammer and coal sizes is maintained by adjusting the wear plate. Coal will crushed into two stage, in fist stage coal will crushed 250 mm to 50 mm and in second stage 50 mm to 20 mm. NOS OF RING GRANULATORTYPE CRUSHER – 04 Nos. Model: 1017U Capacity: 1000 TPH.

TRAVELLING TRIPPER 02 Nos. –
Type: Motorized Traveling type Capacity: 1000 TPH Travel speed:15 m/min Manufacturer: Domacls Engg. (P) ltd Plant Location: CHP MENE END,TAMNAR Industry: POWER Major Equipment: Material Handled: Coal Process: This 1400 wide tripper travels along a belt conveyor and discharges coal into a series of storage bunkers along the path or at the end of the conveyor Direct Bunker Loading: As the tripper moves along the conveyor, a position switch will stop it directly over a bunker. The tripper fills the bunker evenly on both sides until a level indicator inside the bunker tells the tripper the bunker is full. When the bunker is fill ed, the tripper moves on to the next bunker. Continuous Handling: As the tripper is moving and aligning over the bunkers, it does not stop moving coal on the conveyor. While in transit the tripper feeds coal through its center to a bunker at the end of the belt conveyor PLC Controlled: All movements of the tripper are automatically controlled. However manual control is available. Level indicators signal when the bunkers are empty or full
STAGES INVOLVING IN CHP Receiving coal at DUH & reclaiming from hopper & feeding in to primary crusher. Stage wise crushing i.e. primary, secondary, tertiary crushing. Pre screening & post crusher screening. Coal conveying on TP to next TP to meet process requirement. magnetic separation, metal detector, on line weighing, surge hopper, intermittent storage & blending as per process requirement.

Concept of Pipe Conveyor Open Type, Troughed Belt conveyor system has been conventional mode of materials transportation. In the recent years, Pipe conveyor system has revolutionized the concept by introducing an enclosed materials transfer principle. The steel cord belt take a shape of a pipe during forward and/ or return run and flattens itself at the loading and discharge. The idlers are typically arranged in hexagonal array with 3 roll on one side of module and the balance 3 rolls on the other side.
