KIOCL Limited at its Port Facilities department has iron ore grinding unit, filtering unit and loading system for handling the panamax vessels for cargo loading at a draft depth of 13 mtrs. The iron ore fines received by rail and ship are subjected to grinding after primary screening. Through three nos. of Ball mills, the ore is ground by way of wet grinding process.
The ore thus ground is subjected to screening and then filtration. Highly efficient screens are used for screening the ground iron ore with size separation. For filtration of the ground slurry, vacuum disc High Pressure filters are used. The filtered material will have a moisture of around 8.5-11%. This is then carried to a closed storage shed of 2 lakh tonnes capacity. From the storage shed, the ore is fed to the Pellet Plant using a bridge reclaimer.
The Company has another shed for storage of Pellets. About 2.5 lakh tonnes of pellets can be stockpiled there. A bucket-wheel reclaimer is used to load the pellets to conveyors to further carry the pellets to ship, anchored in the berth dedicated to KIOCL Ltd. This can load 5000 tonnes per hour.
Silo and Related Conveyor System:
A storage silo of 8000 tons capacity for storing iron ore fine with connected conveyors is integrated with the grinding and filtration plant. With this system iron ore fines will be stored in the silo and fed to ball mills through an apron feeder, grizzly screen and feed conveyors.
