In a method for producing mixtures of thermoplastic synthetic materials and mineral or organic charge materials, the materials are vacuum mixed and compressed. According to the invention, the mixtures of synthetic materials and charge materials are already homogeneous in a powder state. They are also resistant without granulation to disaggregation, they are stable and can be shaped as products. Moreover, the rigidity must be obviously high but without fragility. The values of the resistance must approach those of the pure synthetic material. Finally, commercial advantages must be attained. To these purposes, the charge materials must be electrically or electrostatically charged before and/or during the mixing with the synthetic materials. As an alternative, this can also be achieved with the synthetic material and even, for instance, through a continuous stirring within an electric field. The charge remains stable during a long period allowing a previous treatment and a storage of the charge material separated from the mixing operation. A combined loading and mixing reactor, together with an installation (57) for producing a strong grinding of the content, is also part of the invention. |
