Energy saving solutions in the Erdenet Mining Corporation

Industrial processes are characterized by the necessity for variation and optimization of the process to achieve satisfactory products and to achieve the most efficient and economic method of production. This calls for the need to control the flow rates of materials throughout the plant so that the most satisfactory condition can be achieved against the many plant variables. During past 10 years Erdenet Mining Corporation has been considerable progress on the development of Variable Speed Electrical drives and these are now proven to be very reliable and economic. It is, therefore, now necessary to reassess the methods used to achieve the variable flow and optimization of industrial processes. This paper is aimed at explaining the energy and costs benefits which can be obtained by using AC induction motors and 3 tariff energy systems for this purpose. Also automatic control system influences on energy saving and reliablity.
