Gravity Sorter Manufacture China

Gravity Sorter

Hebei Julite Sorting Technology Co., Ltd. introduces its Gravity Sorter, a specialized machine that separates particles—seeds, grains, or small mineral fragments—based on minute density and shape differences. The gravity sorter complements conventional sieving by refining batches to meet strict quality or purity standards.

Operating Principle
Inside the gravity sorter, material flows over a slightly inclined, oscillating deck. The deck’s motion and angle, combined with a calibrated airflow beneath, cause particles to stratify according to density and size. Heavier particles remain near the deck surface, migrating in one direction, while lighter or broken particles ride the airflow closer to the deck’s upper layer and migrate differently. Diverter plates at the deck’s end collect separated streams.

Key Adjustable Parameters

• Deck Inclination and Frequency: Control the speed and separation gradient.

• Airflow Underneath Deck: Calibrates lift for different particle densities.

• Feed Rate: Optimizes stratification and minimizes mixing.

Design Highlights

• Modular Frame: Rack‑and‑pinion mounting simplifies height and angle adjustments.

• Air Distribution System: Evenly spaced air nozzles prevent dead zones and ensure consistent performance across the deck.

• Robust Construction: Heavy‑duty steel frame and stainless‑steel deck plate support continuous operation under heavy loads.

• User Interface: Simple controls allow operators to fine‑tune deck motion, angle, and airflow for different materials.

Operational Benefits

• High Separation Accuracy: Capable of distinguishing small density differences (as low as 0.05 g/cm³), essential for premium seeds or de‑stoning operations.

• Low Maintenance: Few moving parts and accessible deck plates reduce cleaning and servicing time.

• Energy‑Efficient: Airflow requirement is modest compared to full aspiration systems, lowering overall energy consumption.

Applications

• Seed Processing: Removal of empty or broken kernels, improving germination rates and seed lot purity.

• Grain De‑Stoning: Secondary separation after sieving, ensuring removal of residual stones.

• Mineral Concentration: Preliminary separation of ore fines by density in small‑scale mineral processing.

• Spice Cleaning: Sorting spices by density to remove husks and debris.
