F-δc curve was introduced into the calculation of radial pressure in barrel of screw press. Based on the principle that the cage bars would bent by the pressure in barrel when the press work, the F-δc curves of certain cage bars were drawn by experiments, and the δc values of certain cage bars in actual work were detected by micrometer, then the F value could be obtained by the F-δc curves, and the actual radial pressure in the barrel could be calculated. The method could be used widely in the pressure calculation in barrel...
