The invention concerns a method consisting in disintegrating clay in the form of particles of not more than 70 mu m wide in diameter, in preparing a slip by adding water and a deflocculant, in spray drying the slip to obtain spherical granules with wetness ranging between 0,5 and 10 %, and in pressing the granules inside a mould under pressure higher than 300 kg/cm<2> (1 kg/cm<2> = 101 300 Pa). |
