Intake / pre-cleaning · Model SCQY
Drum Sieve Pre-Cleaner
First line of defence: straw, string and dust out before anything else sees the wheat.

What it does
The SCQY rotary drum is the cheapest tonne of cleaning you will ever buy. It removes coarse straw, rope, cob and dust before the wheat reaches any precision equipment, which is what keeps the fine screens downstream from blinding.
Technical parameters
Nominal values at standard conditions. Confirm final specification on the order drawing.
| Model | Capacity | Power | Dimensions (mm) | Weight |
|---|---|---|---|---|
| SCQY80 | 8–10 t/h | 1.1 kW | 1650 × 1000 × 1500 | 460 kg |
| SCQY100 | 10–15 t/h | 1.5 kW | 1700 × 1250 × 2100 | 580 kg |
| SCQY125 | 15–20 t/h | 2.2 kW | 2740 × 1600 × 2490 | 900 kg |
| SCQY150 | 20–30 t/h | 3 kW | 2950 × 1860 × 2490 | 1,100 kg |
Selection guidance
Size to 1.3× your peak intake rate — pre-cleaners are often bypassed during harvest rush and you do not want to be the reason a truck waits.
Maintenance
Inspect the drum screen every 200 hours; replace when hole deformation exceeds 15%. Bearing grease every 500 hours.
Selection cross-check
Pre-cleaning screens: drum vs rotary vibrating
Both remove coarse impurities before the main cleaning house. The choice is about capacity, footprint and how dirty the wheat arrives.
This machine
Drum Sieve Pre-Cleaner
SCQY
Choose it when
High-throughput intake where wheat arrives with straw, sticks and large foreign matter. Best when you need to take 30–80 t/h out of a truck pit without a tall building.
Watch out for
Poor at fine separation — it is a scalper, not a grader. Needs a screen change for different grain sizes and cannot handle damp wheat.
Alternative
Rotary Vibrating Screen
HZXZ
Choose it when
Smaller plants (under 20 t/h) where a single compact machine must do coarse and medium separation, and where the building height is limited.
Watch out for
Lower capacity per unit width than a drum sieve. The rotary motion is harder on the screen cloth, so expect more frequent replacement.
Open Rotary Vibrating Screen →Decision rule
Above 25 t/h intake, use a drum sieve. Below that, a rotary vibrating screen is cheaper for the same duty and takes less headroom.
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 →- Does the drum sieve replace a vibrating screen?
- No. It removes only coarse and large impurities. Size grading of small impurities requires a vibrating screen downstream.
