【 摘 要 】

This paper defines the boundaries of changing the screw turn pitch to ensure maximum productivity in transporting a viscous-plastic fluid. A technique is proposed to determine the capacity of screw conduits of oil presses using Bingham viscous-plastic model of extrusion. The numerical modeling has shown a possibility for a significant increase in productivity of the FP oil press by means of optimizing the geometry of the press screw by changing its pitch to the optimal value.
