(i) STORAGE AND RECLAMATION OF ORE

From the Wagon Tipplers WT-B1 and the Track Hopper TH-B1, the raw material

may sometimes be fed directly to the consuming plant in case of emergency.

However, this shall not happen under normal circumstances, when the three

Twin-boom stackers over conveyors Z4B-C1, Z5B-C1 & Z6B-C1 store the raw

material in the designated place of the yard in bed nos. 1 to 6. Flexibility shall

be in built in the Jn Houses Z4, Z5, & Z6 to ensure stacking is trouble free.

Bed blending system shall be possible with the stacker running to and fro on

the length of the pile -or- on a length between two defined position in case

more than one material is stored in a bed marked by travel limit switches,

which through a relay sequencing circuit, with time control-reverses the

traveling gear after the travel in each direction covering the desired length of

the pile. After a layer of some pre -determined amount is deposited in one

traveling direction of the stacker, probes fitted on the stacker boom gives it a

“raise” signal as soon as a net height of material is formed. The next layer is

then formed.

Iron ore may require stockpile formation as described above for blending and

uniformity. However, the emphasis on blending shall be for iron ore fines which

shall be blended while stacking.

Four nos Bucket-wheel reclaimers have been envisaged for bed no. 1 to 6.

All stacking line conveyors feeders and stackers etc. shall have a rated capacity

of 1500 tph & a designed capacity of 1800 tph.

All reclaim line equipment shall have a rated capacity of 1500 tph and a

designed capacity of 1800 tph in the ore handling area.

Reclamation takes place by the conveyors Z7-C3 (Bed no. 1), Z4A-C1 (Bed 2or

3), Z5A-C1 (Bed no.4 or 5) and Z6A-C1 (Bed no. 6) and the reclaimed material

via Jn House Z4A, B, Z5A, B, Z6A and Z6B shall reach Jn House Z7. Two

reclaim conveyors Z7-C1 and Z7-C2 between Z6A to Z7 will receive all the

materials from yard for further transportation.

Reclamation from OHP takes place for the following circumstances:-

Feeding of iron ore lump, dolomite, limestone, manganese, quartzite,

pellet etc. to BF#8 stock house.

Transporting Limestone/ Dolomite (SP grade) and iron-ore fines to fuel &

flux crushing area for Sinter Plant-III.

Two streams of belt conveyors shall reclaim the material from new OHP-B yard

to above places. Belt conveyor Z7-C1 & C2 shall carry the material and

transport thru Z8-C1, C2, Z9-C1, C2, Z10-C1, C2 to Z11-C1& C2 to Junction

house JH-Z11. Junction House-Z11 can discharge the material either to existing

conveyors R103/ R104 of Sinter Plant-III or proposed conveyor Z12-C1/ C2 of

BF#8, with the help of reversible conveyors. To receive the material from Z11-

C1 & C2, suitable modification in existing gallery of R103 & R104 is required.

Also a junction house JH-Z11 with two reversible conveyors & tail end of belt


conveyors Z12-C1 & C2 shall be erected above these conveyors. Further,

conveyor Z12-C1 & C2 and then Z13-C1 & C2 shall move towards stock house

of BF#8 and discharge at JH-Z15 onto reversible shuttle conveyors J15RSC1/2.

The gallery from JH-Z14 to JH-Z15 shall have provision for installation of three

identical conveyors i.e. Z15-C1, Z15-C2 and future conveyor Z15-C3. Suitable

insert plate/ foundation bolts shall be provided for future conveyor Z15-C3.

However, future conveyor Z15-C3 is not in scope of contractor.

Specification of future conveyor:

Length - ~ 35 m: Lift 0.0 m: Capacity 1200 tph: Belt width – 1400mm

Centre to centre distance from Z15C2 – 3010 mm

A junction house JH-Z14 shall be provided in between the junction houses JH-

Z13 & JH-Z15. Two series of belt conveyors shall discharge the Sinter at the

Junction House Z14 over belt conveyor Z15-C1 & C2. Junction House JH-Z14

and conveyors Z14-C1/C2 shall be in the scope of Employer i.e. BSP.

Suitable Junction houses with RCC floors, diverter gates & galleries shall be

provided to transfer the material from one conveyor to another. The scope of

contractor shall finish at JH-Z15 with complete drive and discharge (including

reversible shuttle conveyor) facilities. The receiving belt conveyor below Z15-

C1 & C2 shall be in the scope of Employer i.e. BSP. However, JH-Z15 shall have

a provision (inserts/ foundation bolts) to erect outgoing conveyors to Stock

House.
