MOBISCREEN MS EVO screening plants hit the mark at Orissa Mining’s iron ore site

Wirtgen Group’s Kleemann MOBISCREEN MS EVO screening plants have been helping Kalina Commercial Corp and Orissa Mining hit their goals at the Keonjhar iron ore mine in Orissa, India, classifying material into the desired grain sizes.

Kalinga, which is responsible for iron ore extraction on behalf of the state-owned company Orissa Mining, has been using six MOBISCREEN EVO mobile screening plants from Kleemann to classify the iron ore in up to four fractions.

More than 20 excavators are deployed for extraction, handling and loading of the ore, with 140 large dump trucks transporting the material from the mines for further processing by the screening plants.

Five double-deck screening plants MOBISCREEN MS 952 EVO 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, Kalinga has achieved a continuous daily production target of 30,000 t in two shifts and the desired final grain sizes of 0-10 mm and 10-40 mm.

The MOBISCREEN MS EVO screening plants are able to operate precisely and efficiently under extreme conditions: in the open-pit mining site in Keonjhar, they process feed material with a moisture content of 6-7% without issue.

Dr SR Samal, Managing Director, Kalinga Commercial Corp, said: “We have been using Kleemann screening plants for more than two years. These plants have proved their value with regard to product quality and output. Over the years, they have become an indispensable element of our operation. The service, above all, is exemplary. The co-operation with the Wirtgen Group was crowned with success.”

The classifying screens in the EVO series provide high productivity, good transport properties and first-class screen results, according to Wirtgen. The product series includes the two double-deck classifying screens MS 702 EVO and MS 952 EVO, as well as the triple-deck classifying screens MS 703 EVO and MS 953 EVO. Thanks to the particularly large screening surfaces of 7 sq.m or 9.5 sq.m, high production outputs, combined with effective screening of up to four first-class final products, can be achieved, the company says. Depending on the application case, throughputs of up to 350 t/h (MS 702 and MS 703 EVO) or 500 t/h (MS 952 and MS 953 EVO) are possible.

With the MOBISCREEN EVO screening plants, Kleemann has also considered safety. The plants can be operated with an intuitive control system via a mobile control panel that can be attached at three different points of the plant. This increases work and operational safety.

Easily accessible work platforms mean service activities can be carried out quickly and screen surfaces can be replaced without any problems, the company says. All other service components can be accessed from the ground so maintenance tasks can be executed without complications.
