Title: SINGLE-SCREW PLASTICATOR AND SET OF A SERIES; METHOD FOR PLASTICATING A STARTING MATERIAL
Abstract:
To increase the output, the diameter of the screw is generally increased in accordance with the physical laws of similarity. The length-to-diameter ratio remains the same, or the extruder becomes longer. This has the effect that the engineer seeks to use an extruder with a small screw diameter. The invention addresses the problem of presenting a universal concept of a single-screw plasticator. The invention discloses a compact screw with a diameter of at least 150 mm and with an effective length L that has in relation to the screw diameter D a ratio L/D of 1 to 8.
