| description | PCT No. PCT/AU93/00500 Sec. 371 Date May 3, 1995 Sec. 102(e) Date May 3, 1995 PCT Filed Sep. 30, 1993 PCT Pub. No. WO94/07595 PCT Pub. Date Apr. 14, 1994The specification describes a process for pelletising particles of an alkali metal ferrite with an aqueous binder such as a black liquor derived from pulping wood chips. The particles are ground and fed to a microgranulator in measured quantities together with measured quantities of aqueous binder. The particles are ground such that they have an even size distribution about a mean in the range from 25 to 50 microns. The particles are mixed with the binder in the microgranulator to form microgranules which are fed to a pelletising pan. The temperature of the microgranules on the pelletising pan is controlled by cooling either or both the alkali metal ferrite or aqueous binder prior to measuring them into the microgranulator. A pan temperature of less than 70 DEG C. is disclosed. |
