Duration: 2014 - 2015

Scope: the complete sintering line from raw material input to sinter feed output and auxiliary facilities, including fuel crushing, proportioning, primary mixing, secondary mixing, sintering, circular cooler, machine head deduster, main draft fan house, main chimney, finished product screening shop, transfer station, belt conveyor gallery, together with power supply & distribution, water supply & drainage, ventilation & dedusting facilities, gas, steam and compressed air supply, communication, roads, comprehensive pipeline, main control building for Stage I & II, all high and low voltage distribution rooms of 35kV, 10kV and 0.4kV within battery limit of sintering.

Project features: stable and proven practical process and equipments were used. Advanced and economic PLC system was equipped to ensure smooth production process and product quality. To meet the requirement of energy saving and environment protection, thick bed sintering (side place height 850mm) and mixed material preheating process were used. Utilization of new-type circular cooler reduced operation cost and air leak rate, in which way the efficiency of waste gas heat was improved.
