CHAP-03 BRIEF SYSTEM DESCRIPTION Page 15 of 20
vibro feeder (6nos.) and fed to flux screens (6 nos.) for screening -3mm
size fraction. The under size (-3 mm) from each of the six screens is fed
to a common conveyor L120 which conveys the material onward to
storage and proportioning bin building. The oversize (+3mm) is fed to a
common conveyor L115 and recycled back to flux crushing building for
further crushing.
03.04.02.03 PROPOSED Fuel and Flux Crushing and Screening Facility
In order to cater to increased requirement of fuel and flux for the new
sinter machine, following three facilities have been envisaged under this
package which shall form part of scope of this Contract:
• Up gradation / Addition of coke crushing and screening facilities.
• Up gradation / Addition of Coke Grinding facilities
• Up gradation/Addition of Flux crushing & screening facilities.
The existing facilities also need to be modified/ extended so as to
integrate the existing with proposed facilities.
03.04.02.03.A UP gradation / Addition of coke crushing and screening and
grinding facilities
A similar facility for coke breeze crushing, screening & grinding with
related facilities shall be added adjacent to the existing one.
As described earlier that the coke breeze is being received from the
existing track hopper via belt conveyors C101, C102, C103, C104 to the
coke storage yard. It is now proposed that Coke breeze & BF return
fines shall also be received by conveyor C-102 for further transportation
to coke storage yard. Belt conveyor C-104 shall be suitably modified &
extended and discharge onto new reversible conveyor RC 106. RC 106
shall be able to discharge either onto existing conveyor C106 or onto
new conveyor C106A in a new Junction house CK-1. Conveyor C-106A
shall carry the material to feed over a hopper of capacity 200m3
(effective volume) with suitable gate at proposed New Coke crushing
house CK-2. A reversible belt conveyor RC-CK2 will receive the material
