Linear sinter cooler


Linear sinter coolers are designed for cooling of the sinter, grain size is not more than 150 mm, with initial bulk temperature not more than 750 °С up to the temperature not more than 100 °С, by means of forced air vent through sinter layer on the fire grate.
Advantages of linear coolers in contrast to ring and pan coolers, and etc.:
– more convenient for sinter plants arrangement;
– lift a sinter and transport it to sorting simultaneously, that make possible to reduce the sintering housing height;
– simple design allow to reduce maintenance and repair costs;
– simpler carrying out of uniform and qualitative sinter laying, as well as spillage remove;
– equipment operation within 20 years without replacement of base units and at minimum costs for repairs;
– efficient air rate of blowing for cooling ton of sinter –1800…2300 m3;
– short down time for equipment repair — up to 5%;
– lubrication process automation of bed chain articulating joints;
– possibility of waste-gas heat recycling, etc.
