Disclosed is a process for continuously producing a material contacted by a treatment agent, which material has a bulk density of about 0.16 g / cm ** 3 or less. According to the invention, the material is contacted with a treating agent as it is transferred in dense phase from a storage container 10 to a container 30; the material can be heated after contact if necessary. The invention applies in particular to the production of fillers or reinforcing agents for improving the physical properties of compositions comprising rubbers, coatings, adhesives, paints and sealants. |
