Thyssenkrupp wins semi-mobile-crushing-plant contract in India coal hub

The plants will be used for a new 15 Mt/y coal handling plant (CHP) operated by a subsidiary of India’s largest public sector coal mining company, thyssenkrupp said.

Looking to boost production from 10 Mt/y to 25 Mt/y, the miner is implementing an in-pit crushing and conveying system utilising the in-pit SMCP for the CHP, which will, thyssenkrupp says, make the production process more efficient and stable.

thyssenkrupp won the contract from an India-based engineering procurement and construction contractor. It involves the complete design, engineering, manufacturing and supply, and “TAG services” for the three semi-mobile crushing plants.

The plants consist out of three separate modules.

The receiving hopper module comes with a 2.2 m wide and 10.5 m long, heavy-duty apron feeder, which can be fed by trucks and has a capacity of around 150 tons (136 t).

The heart of each plant is the crusher module, which uses a RollSizer DRS 1,000 x 2,250 (centre distance x length of the roller) for a maximum feed capacity of 1,900 t/h.

The third module is the electrical building with the operator room. By separating this module from the crusher module, the operators and electrical equipment are not exposed to any vibrations from the crushing process. This ensures the plants meet all requirements from a health and safety perspective, while guaranteeing a long life of the electrical equipment, thyssenkrupp said.

“Compared to stationary crushing plants, SMCPs are more flexible and can be relocated when the distance between the mining area and the crushing plant increases and, thereby, can reduce the cost for transport of the run of mine material significantly,” thyssenkrupp said.

“thyssenkrupp can look back on a long history of supplying fully-mobile, semi-mobile, and stationary crushing plants, which makes the company a leading partner for the engineering, construction and service of industrial plants and systems for the coal industry.”
