Abstract

See full text

A method for manufacturing green or thermally treated briquettes which are made up of at least one quick calcium-magnesium compound that is an iron-based compound. The method includes the steps of supplying a homogeneous pulverulent mixture to a roller press, the press having pockets where the pulverulent mixture is compressed to form the green briquettes. The rollers of the roller press develop linear speeds at the periphery of the rollers between 10 and 100 cm/s and linear pressures between 60 and 160 kN/cm. The method can also include a thermal treatment of the green briquettes to produce fired briquettes containing calcium ferrite, the briquettes having a Shatter Test Index less than 8%, and a porosity value greater than or equal to 30%.
