Method of producing magnesium chloride granules
A method of producing magnesium chloride granules with a particle size in the range from 0.4 to 3.0 mm suitable for fluidization, air drying and chlorinating to anhydrous state, by preparing a feed solution of MgCl2 having a 30-55% by weight of MgCl2, feeding the solution and keeping it at high temp...

| description | A method of producing magnesium chloride granules with a particle size in the range from 0.4 to 3.0 mm suitable for fluidization, air drying and chlorinating to anhydrous state, by preparing a feed solution of MgCl2 having a 30-55% by weight of MgCl2, feeding the solution and keeping it at high temperatures from the feeding tank to the nozzles, atomisation of the feed solution into the bed of already dried particles by pressure or compressed air, passing preheated air upwardly through the bed, maintaining the particles in a fluidizing state and a bed temperature between 100-170° C., continuously recovering entrained particles in a cyclone, discharging magnesium chloride particles continuously, classifying discharged material and recycling of any undersized fraction and crushed oversize fraction together with fines from the cyclone to the fluid bed for further granulation. |
