Wheat Seed Cleaning Line with Gravity Separator China

Wheat Seed Cleaning Line with Gravity Separator China

Shijiazhuang Xinlu Technology Co., Ltd. introduces the Wheat Seed Cleaning Line with Gravity Separator, an integrated system that combines mechanical sieving, aspirating airflow, and density stratification to deliver consistently cleaned seed batches. This specialized configuration addresses both coarse and fine impurities in a compact footprint.

Cleaning Sequence

1. Intake & Pre‑Cleaning

• Wheat enters a vibratory screener that removes large contaminants—straw pieces, clods, and oversize particles—while an aspirator fan draws off light debris such as dust and chaff.

2. Magnetic Separation

• A magnetic drum eliminates metal fragments, safeguarding the gravity separator and downstream equipment.

3. Gravity Separation

• The heart of the line features a gravity table where deck vibration and adjustable airflow stratify kernels by density. Denser, healthy wheat sinks and advances toward the clean‑seed outlet; lighter debris and damaged kernels are removed via the airflow stream.

4. Final Dedusting

• A secondary aspirator module polishes the cleaned seed, lifting residual fine particles before transfer to packaging or further processing.

Design Highlights

• Dual‑Stage Air Handling: Independent aspirators for pre‑cleaning and final dedusting ensure precise control over particle removal.

• Adjustable Separation Parameters: Operators can modify deck angle (0–10°), stroke amplitude (3–7 mm), and airflow rate (1–4 m³/min) to match seasonal variations in seed moisture and impurity levels.

• Robust Construction: Abrasion‑resistant steel decks and wear‑resistant linings ensure long service life, even under continuous operation.

• Compact Layout: Integrated modules occupy minimal floor space, making this line suitable for retrofit into existing facilities.

Performance and Benefits

• Impurity removal rates above 90% for common contaminants such as broken kernels and weed seeds.

• Throughput capacities ranging from 10 t/h to 25 t/h, depending on seed condition.

• Minimal kernel breakage due to gentle deck oscillation and airflow control.
