Sizers and Graders

Flat Screen Grader

Seed and grain kernel sizing/classifying is done to present a more uniform product either for human consumption or replanting (seed). Some commonly sized commodities are corn (maize), sunflower, cereals, nuts, rice, and snack food grains. These flat screen units provide good separation efficiency by means of slotted holes for cereal grains and a number of other perforation options are available. We have numerous screen sizes and multiple levels to accommodate your capacity requirements. We have aspiration options available to keep operate dust free or utilize aspiration columns for lifting light particles and light kernels.

Cylinder Sizer

Seed and grain kernel sizing is done to present a more uniform product either for human consumption or replanting (seed). Some commonly sized commodities are corn (maize), sunflower, cereals, nuts, rice, and snack food grains. These cylindrical cylinder units allow for a high degree of sizing accuracy, compared to our flat screen sizers, by means of slotted hole perforations (width separation of flat from round kernels) and round hole perforations (thickness separation of small from large kernels). This units can be stacked in parallel (all modules dressed with the same cylinder size for increased capacity) or series (for multiple separations). Modules can be made up in 1, 2, 4, or 6 cylinder units.

Model Capacity*, metric tons (bu.) per hour Power, kw (hp) No. 1 2 (80) 0.37 (0.5) No. 2 4 (160) 1.5 (2) No. 4 8 (320) 1.5 (2) No. 6 12 (480) 1.5 (2)

Note: Capacity* is based on sizing corn (maize), round from flat kernels, and will vary by crop and the percentage of particle size range.
