Durchgangs zwischen den Abquetschwalzen eine schräge Richtung ein, die derjenigen der Kanäle 2 entspricht.Passage between the squeegee rollers in an inclined direction, that of that of the channels 2 is equivalent to.
Das in F i g. 3 dargestellte Filterband besteht aus nebeneinanderliegenden schrägen, undurchlässigen Lamellen 11 und schrägen, porösen Lamellen 12. Diese Lamellen 12 können aus porösem Tuch bestehen. The in Fig. 3 filter tape shown consists of adjacent, inclined, impermeable Lamellae 11 and inclined, porous lamellae 12. These lamellae 12 can consist of porous cloth.
Die Abmessungen, Winkel, Verteilungen der Kanäle, Dicke des Bandes, Deformierbarkeit usw. werden natürlich den zu behandelnden Produkten, den Geschwindigkeiten und anderen Bedingungen des Abquetschens angepaßt. Insbesondere kann es in gewissen Fällen vorteilhaft sein, an der Oberseite ein Filtertuch einzufügen, um eine Verschmutzung des Bandes zu begrenzen oder seine Abdrücke auf das zu konzentrierende Material zu verringern.The dimensions, angles, distributions of the channels, thickness of the tape, deformability etc. of course the products to be treated, the speeds and other conditions of the Squeezing adapted. In particular, it can be advantageous in certain cases to have a Insert filter cloth to limit contamination of the belt or its marks on it reducing concentrating material.
Ferner können gleichzeitig zwei gleiche endlose Bänder verwendet werden, die beiderseits der Schicht des zu behandelnden Materials angeordnet sind.Furthermore, two identical endless belts can be used at the same time, on both sides of the layer of the material to be treated are arranged.
