A Study On Energy Conservation In Textile Industry

aug 31, 2013 In textile mill, electricity consumption is in increasing trend, due to modernised machines and continuous usage of the equipments in inefficient operating parameters. the energy cost is around to over the production cost and it stands next to raw material cost. hence now a days area of focus is towards energy consumption at load end and by optimizing the efficiency of the motor.below microns, the advantages of a horizontal stirred mill become dramatic and below a certain point, the horizontal stirred mill is the only choice as a ball mill cannot produce a micron product at any practical power consumption.
