NLC has also entered into an agreement with National Institute of Technology, Tiruchi for improving energy efficiency of conveyors.
The project tests use of Programme Logic Control Circuit in the conveyor systems which will permit all motors to work only while starting the conveyor and then depending on the load will operate just the required number of motors automatically.
Over two million units of electricity can be saved in each conveyor system. NLC uses 50 conveyor systems in its second mine and can save over 31 crore annually. The research project is estimated to cost about 1.22 crore with NLC contributing 58 lakh and the NIT 63 lakh.
