Method for producing hematite pellet

The invention relates to a hematite ball group's production method. It is take hematite carries on the ingredient as the main raw material, after matches the good material mix even, enters makes the ball machine to make the fresh ball, then the use chain fire grate machine will live the ball to be dry, preheating, the preheating after ball group enters in the rotation cellar to roast to 1100deg.C~~1350deg.C, the fuel which the roasting will use for the solid fuel (for powdered coal or coke powder), after the roasting ball group will enter in the cooling system to cool, forms the end product. Hematite accounts for the hard powdered ore total quantity which the ball group ingredient uses 80%~100%. Compares had technical this invention to have the following merit: 1st, take hematite as the main material production ball group, the resources origin is widespread. 2nd, (by powdered coal or coke powder) makes the fuel by the solid fuel, compared to gaseous fuel price low, the resources is rich, is advantageous for the promotion.
