Key Technical Parameters: 5XFZ-25SC Air Screen Cleaner with Gravity Table

Comprehensive Process Flow of the Air Screen Cleaner with Gravity Table

The cleaning process for the 5XFZ-25SC air screen cleaner with gravity table is meticulously designed to ensure maximum purity and efficiency, integrating several stages of separation. Initially, raw grain enters the feeding hopper and is uniformly distributed into the air aspiration system. Here, a controlled airflow removes lighter impurities such as dust, chaff, and undeveloped grains. This preliminary air separation significantly reduces the load on subsequent cleaning stages, enhancing overall machine performance and extending the lifespan of the screening components. The aspiration system's fan speed and damper settings are precisely adjustable to accommodate varying grain types and impurity levels, ensuring optimal removal without unnecessary loss of good grain.

Following aspiration, the grain proceeds to the multi-deck vibrating screen system. These screens are custom-perforated to separate grains by size, effectively removing oversized foreign materials (like straw, large stones) on the top screens and undersized impurities (like sand, small broken grains) through the bottom screens. The oscillation frequency and amplitude of the screens are finely tuned to promote efficient stratification and separation. The sieving system incorporates a self-cleaning mechanism, often involving rubber balls or brushes, to prevent screen clogging and maintain consistent throughput. This mechanical separation is crucial for preparing the grain for the final, more precise density sorting.

The core of the advanced separation lies in the integrated gravity table. Grain that has undergone air aspiration and screening then flows onto the gravity table, which vibrates and has a precisely controlled airflow rising through its perforated deck. This combination creates a fluidized bed, causing lighter impurities (e.g., shriveled kernels, diseased grains, small stones, or soil clods with similar sizes to good grains but different densities) to float above the heavier, good grains. The table's adjustable inclination and vibration frequency further aid in stratifying the material, allowing the denser, pure grain to discharge at one end, while the lighter impurities are discharged separately. This highly effective density-based separation is critical for achieving the highest purity standards required for seed processing and premium food-grade commodities.

Manufacturing Process & Quality Assurance

The manufacturing of the 5XFZ-25SC air screen cleaner with gravity table adheres to stringent quality control protocols, leveraging high-grade materials and advanced fabrication techniques.
