The Stress relief process of the beam and the ring (red arrow indicates tensile stress; blue arrow indicates compressive stress). (a) Process of feed roller pressed down for the three-roller bending beam; (b) Process of feed roller lifting for the three-roller bending beam; (c) Process of feed roller pressed down for the ring; and (d) Process of feed roller lifting for the ring.

Sketch diagram of melt spinning of CNTs/PLA composite filaments. 1—screw machine, 2—main feed throat, 3—side feed throat, 4—four heating zones, 5—single screw, 6—elbow pipe, 7—spinning box, 8—metering pump, 9—spinning pack, 10—annealing device, 11—cooling device, 12—oil roller, 13—the first hot roller, 14—the second hot roller, 15—the third hot roller, and 16—winding device.

Milling scheme for the roller milling system (PRM). All extracted flour fractions (B1–B6, C1–C6, R1–R3, fine, and coarse bran fraction as well as animal feed) were collected separately.

Comparison between intended and observed particle sizes. (A) Intended particle sizes are 0.8, 1.2 and 1.6 mm. (B) The particle sizes observed after sampling in the feeder, using wet-sieve analyses, representing the compound feed offered to the birds. Each line corresponds to all of the processing steps. HM: hammer mill; RM: roller mill; Exp: expander; Pel: pelleting.
