Primary cleaning · Model TQLM
Plane Rotary Sifter
Gentle, enclosed and dust-free — the polite screen.
- 60+ years manufacturing
- 10–500 t/d capacity range
- 100+ patents
- Turnkey commissioning
What it does
The TQLM separates large and small impurities through a slow planar rotary motion inside a fully enclosed sieve boat. Because there is no vertical throwing action, it damages grain far less than a vibrating screen — which is why it is preferred for seed cleaning and malting barley.

Selection guidance
Use this where grain damage matters — seed stock, malting barley, specialty wheat with a premium on kernel integrity. For bulk commercial wheat, the cheaper vibrating screen is adequate.
Maintenance
The eccentric drive runs in an oil bath; change oil every 2,000 hours and check the flexible coupling for fatigue every quarter.
Selection cross-check
Primary screens: self-balancing vs plane rotary
Once coarse impurities are out, the wheat needs efficient size grading. Both machines do it; they differ in how the motion is generated and what that costs.
This machine
Plane Rotary Sifter
TQLM
Choose it when
Smaller mills and pre-cleaning duties where gentle action matters, or where the wheat is fragile and you want to minimise breakage.
Watch out for
Lower capacity per unit area. The eccentric drive is simple but imposes a reaction force on the structure, so it needs a heavier support frame.
Alternative
Self-Balancing Vibrating Screen
TQLZ
Choose it when
The default choice for any plant above 10 t/d. The counterweight system cancels the reaction force, so it can be mounted high in a frame without transmitting vibration into the structure.
Watch out for
More bearings and a more complex drive than a plane rotary sifter, so maintenance skill matters. Rubber mounts need replacing on a 2–3 year cycle.
Open Self-Balancing Vibrating Screen →Decision rule
Self-balancing for capacity and structural freedom; plane rotary for gentleness and simplicity at small scale.
Answers
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 →- Can the TQLM replace a vibrating screen entirely?
- In capacity terms no — it is a lower-throughput machine. It is usually installed as a second-stage screen or where kernel integrity is a commercial requirement.
