5XFZ-25S Air Screen Cleaner + Gravity Table + 5XFJ-10C Vibration Grader

In seed plants and flour mills, the quiet star of uptime is a good grading machine for wheat. I’ve toured enough lines to know: when the cleaner is dialed in, everything downstream just behaves. This integrated setup from Shijiazhuang, Hebei—an area that’s become a bit of a northern hub for grain equipment—packs elevator, air screen, gravity separation, and vibration grading into one line. To be honest, the all-in-one trend is accelerating for a reason: fewer handoffs, sharper yields.

What it does, in plain terms

Model: 5XFZ-25S with 5XFJ-10C. It cleans sesame and beans too, but most folks I meet run wheat first. The line delivers about 8 tons/hour and pushes purity above 99.5%—that’s in published specs and echoed by operators I talked to. The elevator feeds consistently, the air screen knocks out chaff and dust, the gravity table lifts out stones and light shriveled kernels, and the vibration grader finishes by sizing for uniformity (milling loves that).

Process flow and testing

• Material: wheat, sesame, beans; moisture ideally 12–13.5% before cleaning.
• Methods: pre-aspiration, multi-deck screening (per EN ISO 5223 sieve sizes), gravity separation, final grading.
• Testing standards: impurity rate and dockage by USDA FGIS methods; moisture by ISO 712; sieve selection aligned to ISO 5223.
• Verification: FAT at factory and SAT onsite; particle size distribution charts help lock settings.

Where it fits

Seed processing plants, flour mills, farm cooperatives, even contract cleaners. Many customers say the integrated footprint saves two operators per shift. And yes, dust control matters—ask for enclosed aspiration if you can.

Customization and upkeep

• Screens: slot/round hole sets for local wheat varieties; quick-change frames help.
• Air system: adjustable shutters, frequency control for fans.
• PLC add-on: recipe presets for wheat vs. sesame (handy, actually).
• Wear parts: elevator buckets, sieves, vibration springs—budget annual replacements.

Field note (mini case)

A mid-size flour mill in Punjab ran the line at 7.5 t/h on hard wheat, moisture 12.8%. Post-cleaning purity averaged 99.6% by FGIS dockage method; broken kernels dropped ~15% after tuning the gravity table. Operator feedback? “Less babysitting than our old two-machine setup.”

Final picks and a small reminder

If you’re speccing a grading machine for wheat, ask for sieve lists per ISO 5223, a FAT checklist, dust emission figures, and after-sales response times. Also confirm ISO 9001 scope and CE DoC—paperwork matters. For higher-protein wheat, a grading machine for wheat with tighter air control pays for itself in fewer downgrades. For mixed-crop plants (sesame/beans), modular screens will save your weekend.
