An improved conveyer apparatus for processing and degassing a mixture of materials for forming solid surface end products, such as cultured marble and other polymer casting products. The conveyer includes a conveyer housing with an internal passageway having a conically shaped upstream section and a downstream section. A rotatable screw is located in the internal passageway and has a shape that corresponds to the shape of the internal passageway, so that an upstream section of the screw is conically shaped. The upstream section of the passageway has an inlet that connects to a source of materials, such as a mixer, and the downstream section has an outlet that permits the mixture of materials to exit the conveyer apparatus. A vacuum source is connected to the conveyer housing to remove gases from the mixture as it is being conveyed through the conveyer.

onvoyeur amélioré pour le traitement et le dégazage d'un mélange de matériaux et former des produits finaux présentant une surface solide, par exemple du marbre synthétique ou d'autres produis moulés à base de polymères. Le convoyeur comprend une enceinte avec passage interne avec section amont en forme de cône et avec section aval. Une vis pouvant être tournée se trouve dans le passage interne, de telle sorte qu'une section amont de cette vis présente une forme conique. La section amont du passage comporte une entrée jointe à une source de matériaux, par exemple un malaxeur, et la section aval comporte une sortie permettant au mélange de matériaux de quitter le convoyeur. Une source de vide est raccordée à l'enceinte du convoyeur et assure l'élimination des gaz du mélange lorsque celui-ci passe dans le convoyeur.
