Iron ore mining in India
India is bestowed with large reserves of Iron Ore and is the 2nd largest producer of Steel across the globe. India’s total Iron Ore production for the year CY19 was 231 Million MTs, which enabled 90% (111 million MTs) of steel production. Hematite and Magnetite are the most prominent of the Iron ores found in India, of which, Hematite is considered to be the most important because of its high-grade quality and lumpy nature; it is consumed by a large number of steel and sponge iron industries in the country.
Odisha and KCCL
Odisha is a significant contributor to India’s total Iron ore production. Odisha Mining Corporation (OMC), a state-owned entity, has awarded its Iron ore mining contract to Kalinga Commercial Corporation Limited (KCCL) for its Gandamardhan Hill Top mine located at Keonjhar, which is 200 kms from Bhubaneswar, the capital city of Odisha.
KCCL uses the open pit mining technique by developing benches from top to bottom to extract the ore. Run of mines (ROM) excavation is done by drilling and blasting. More than 20 Excavators having bucket capacity ranging from 2.1 cubic meter to 4 cubic meter are used for excavation, handling and loading of the ore, followed by approx 140 mining and dumping trucks with capacities ranging from 19.5 cubic meter to 24 cubic meter to help transport the material from the mines to screening plants to get the output in the required sizes.
Kleemann Mobile Screening Plants
6 Kleemann Mobile Screening plants are deployed on the Keonjhar site since Jan 2020 to systematically screen the final output of the required sizes. Five of the mobile screens are of double deck configuration (MS 952 EVO) with three outputs and one Screen is of triple deck (MS 953 EVO) with four outputs. With the deployment of these 6 Mobile Screens, KCCL has continuously met a daily production target of 30,000 MTs by operating in two shifts.
KCCL’s output requirement is of 0-10 mm (Fines) and 10-40 mm (Lumps). Kleemann MS 952 with its two-deck design and large screening area of 9.5 sqm is able to effectively segregate the lumps and Fines to meet the quality demand.
Dr. S. R. Samal, Managing Director, KCCL, informs, “We have been using Kleemann screen plants for more than two years. These screen plants have shown good performance and production. Over the years, they have become an inseparable part of our operations. The service provided by the customer support team has been exemplary. Our association with the Wirtgen Group has been very fruit- ful. The Screening Plants have passed the test of time and conditions with flying colors and are worth the money spent on them as we have achieved our targets well within the stipulated time, and are pleased to be associated with the Wirtgen Group.”
Kleemann mobile screens are offered with 2 and 3 deck configuration and screening areas of 7 sq.m and 9.5 sq. m. These machines can operate at 4 different inclination angles that can be adjusted from 20 degrees to 31 degrees, based on application requirements.
The Screens come with 1200 mm and higher width discharge conveyors, capable of accumulating bigger stockpiles of material under its conveyors, resulting in less frequent use of loaders to shift the stockpiles.
The Screening plants are powered by a highly efficient power pack with an option of external power supply for cost-effective and environment friendly operation in case of availability of power supply on job sites.
Kleemann intuitive touch screen control panel offers intuitive and user-friendly operation. This makes the machine set-up a one-person job. The control panel with its 25 m cable can be connected at three different positions, which ensures that the executed functions are clearly visible and high work and operation safety can be guaranteed. To prevent any manual errors, the screening plants are equipped with proportionate valve control for safe and precise movements.
As an optional component, Kleemann offers wireless remote to provide more flexibility in operation of the machine and also an optional water sprinkling system for dust suppression.
Kleemann screening plants are equipped with Wirtgen Telematics system which provides remote access to the customer for monitoring the machine parameters like hour meter reading, location, fuel consumption data, availability, service, and maintenance schedule.
The “Made in India” Kleeman screen is a global product being exported worldwide. Wirtgen India is the largest exporter of these screening plants from India.
