Sifting · Model FSFJ-D
Double Bin Plansifter
Two independent bins, one frame — the small plant standard.
- 60+ years manufacturing
- 10–500 t/d capacity range
- 100+ patents
- Turnkey commissioning
What it does
Twin-bin sifters dominate the 15–40 t/d range because they deliver plansifter-grade grading on a frame that fits under a normal ceiling. Each bin runs independently, so you can sift two different streams without cross-contamination.
Technical parameters
Nominal values at standard conditions. Confirm final specification on the order drawing.
| Parameter | FSFJ double bin |
|---|---|
| Main shaft speed | 245 rpm |
| Gyration diameter | 45–50 mm |
| Sifting area | 5 m² per bin |
| Power | 1.1 kW |
| Dimensions | 2200 × 1450 × 2000 mm |
Selection guidance
Specify the number of bins and the sieve stack at order — the frame is standard but the internal stack is bespoke to your flow sheet. Changing it afterwards is possible but costs a rebuild.
Maintenance
Check the flexible connections between bins annually; a perished sleeve leaks flour into the wrong stream and is difficult to diagnose.
Selection cross-check
Plansifters: single bin vs double bin vs high square
Sifting is the second-largest power consumer and the constraint most flow sheets hit first. Bin configuration determines capacity per unit floor area.
This machine
Double Bin Plansifter
FSFJ-D
Choose it when
Plants of 40–100 t/d where floor area is limited and you need two independent sifting streams in one frame.
Watch out for
Two bins share one drive, so a drive failure stops both streams. Access to the inner bin is tighter for screen changes.
Alternative
Single Bin Plansifter
FSFJ
Choose it when
Small plants (under 40 t/d) with few passages, or as a dedicated machine for one product stream such as semolina or bran.
Watch out for
Lowest sifting area per square metre of floor. In a multi-passage flow sheet you would need several, each with its own drive and hangers.
Open Single Bin Plansifter →Alternative
High Square Plansifter
FSFG
Choose it when
Plants above 60 t/d, and the standard choice for any 4B5M1S1T flow sheet. Maximum sifting area per unit footprint, with each section independently fed.
Watch out for
Tall — needs 12.5 m or more of building height in a storey-typed plant. Section changes require working at height with proper access platforms.
Open High Square Plansifter →Decision rule
Sizing rule of thumb: 1 m² of sifting area per 0.8 t/d of capacity for a 4B5M flow sheet. Choose the configuration that delivers that area in the footprint you have.

Frequently asked questions
Straight answers to the questions engineers and mill owners actually ask us during plant sizing. If your case is not covered, send the wheat specification and your target tonnage.
Ask an engineer →- How many sifters does a 25 t/d plant need?
- Two twin-bin units, typically one for break and coarse reduction streams and one for the reduction and flour streams.
