The vanadium titanium magnetite concentrate has some characteristics， such as low iron， low silica， high tatanium， high ferrous iron and so on. The magetite concentrate is used as sinter main raw material， which is easy to produce sinter with mineral structure of high melting point， and to make the sinter strength low. Aiming at these difficulties， Desheng sinter engineering adopted single fuel breaking， proportioning focusly， intensifying granula- tion， newly-wide belt and nine rolls distributor， implementation of low silica high basicity and deep bed sintering. The sinter machine applies intelligent integrated lubrication system，sealed slide spring， and soft magnetic seal to low leakage. When putting into operation， the sinter ore strength is increased to more than 72%. The sinter process energy consumption is 49.34 kg/t.
