SWIFT SCREENING SOLUTION
Mobile screening plants in a large-scale operation in India T
he red colour usually allows you to spot it from a distance: iron ore. Te volcanic rock is mainly used in the manufacture of steel. India
has vast reserves of iron ore and is the second biggest steel producer in the world. Mobile screening plants from Kleemann are used during the extraction of the important material. India’s total iron ore production for 2019 was 231 million tons, around 90% of which was used in domestic steel production. Hematite and magnetite are the iron ores mainly found in India. Tanks to its high quality and lumpy properties, hematite is the most sought- after iron ore for the local steel industry. Due to its fine grain properties, the processing method of the sedimentary rock usually demands a lot from the
screens. Tis is where the classifying screens called Mobiscreen MS Evo provide a valuable service. In an iron ore extraction site in Keonjhar in the federal state of Orissa, Kalinga Commercial Corporation (KCCL) is responsible for iron ore extraction on behalf of the state-owned company Orissa Mining Corporation.
IRON ORE CLASSIFIED INTO UP TO FOUR FRACTIONS Since January 2020, six Mobiscreen Evo mobile screening plants from Kleemann have been in use at the Keonjhar location screening material to the desired final grain sizes. More than 20 excavators are deployed for extraction, handling and loading of the ore. 140 large dumper trucks transport the material from the
mines for further processing by the screening plants. Five double-deck screening plants and a triple-deck screening plant (MS 953 Evo) make classification of the blasted and then crushed material into up to three or four (with the MS 953 EVO) fractions possible. With the use of these six mobile classifying screens, KCCL has achieved a continuous daily production target of 30,000 tons in two-shift operation. Te desired final grain sizes of 0-10mm and 10-40mm are thus produced.
SCREENING PLANTS ALSO IMPRESS UNDER EXTREME CONDITIONS Te screening plants also operate precisely and highly efficiently under extreme conditions: in the iron ore open pit
Iron ore can be spotted from a long distance due to its red colour
