New-type ring sintering machine is the major equipment of the middle and small smelting enterprises’ smelting factories for sinter production before iron smelting. After sintering in sintering machine, the mixed materials containing various contents generate hot sinters to be used in blast furnace or electric furnace ; after crushing and cooling. The quality sintering ore are the important guarantee for electric furnace and blast furnace smelting indicators. 


1. The integrated operation of automatic proportioning, mixture, sintering, crushing and air cooling features compact process, continuous production, sufficient output meeting the standard, thus saving labor cost and reduced energy consumption.


2. During proportioning, the disc machine blends the materials in proportion to meet requirement of the blast furnace on the alkalinity.


3. The mixing process is a combination of the primary mixing and the secondary mixing. Through scientific calculation, the reasonable rotate speed can make the mixed materials mixed evenly; the formed granules have well ventilation function during sintering and speed up the sintering. 


4 This sintering machine is ring-shaped one featuring advantages such as small volume, compact structure, continuing operating, high output. Above all, it sues coal gas ignition combustion, realizing energy recycle and reducing production cost. 


5. The close combination of material crusher and sintering machine saves time, cost and other expenses during operation. 


6. Save about 50% of investment, 50 % consumptive cost, 10 kwh/t power consumption and 50% maintenance cost .

7   successfully used in the nickel ore sintering, chromes ore sintering, manganese ore sintering and iron ore sintering.
