| Abstract: | Based on the idea that volume become smaller gradually in the screw expeller, a mathematical model of the screw is deduced. The pitch of the screw can continuously change in the forward direction with the increment of a polynomial expression to the third power. A design calculation method based on the volume press ratio is also presented. All the design calculation and drawing process are completed with an aid of computer. |
