Import Blow& Draw Type Gravity Separator — Buy in wholesale FOB from Supplier in China

The Blow and Draw Type Gravity Separator from Yongming Machinery Manufacturing Co., Ltd. is a precision sizing and density classification machine engineered for agricultural commodities. It separates materials that share identical physical dimensions, length, width, thickness and shape, by exploiting differences in specific gravity through controlled positive and negative air pressure. The unit processes beans, seeds, nuts and dried flower products, removing straw, branches, stones and imperfect seeds or grains. It achieves this through fluidisation of granular material, where adjustable wind pressure and eccentric shaft settings create gravity segregation, large proportion material sinks while lighter fractions float upward.

The machine employs axial flow fans connected to a pulse-jet bag filter dust collector for contained, clean operation. Multiple discharge outlets correspond to different density fractions, including a dedicated stone outlet for heavy contaminants. The system is designed to achieve target thousand seed weight and uniformity specifications for each material batch. Typical industrial gravity separators operate with air velocities between 1.2 and 2.5 m/s depending on crop type, with eccentric shaft speeds adjustable from 180 to 320 rpm for fine tuning separation efficiency.

Buyers include seed processing facilities, grain export houses, nut processors and specialty crop handlers who require density-based purity standards for certification and market access. The machine is typically positioned after pre-cleaning and length/width grading, and before colour sorting or packaging. Import buyers should confirm with Yongming Machinery whether the unit is supplied with fan and dust collector as standard, or as optional modules, and verify electrical specifications for their destination voltage and frequency.

Yongming Machinery Manufacturing Co., Ltd. is based in Langshan Town, Linhe District, Bayannaoer City, Inner Mongolia, China, with postal code 015000. The company holds a harbor trust tier on the platform, though its response rate is recorded at 0.00 percent with zero average response hours, which indicates limited or no recent engagement through the platform messaging system. The supplier's profile does not state year of establishment, registered capital, factory size, employee count, annual revenue or specific export markets, so these should not be assumed.

The listing presents the Blow and Draw Type Gravity Separator as a core product, with technical detail suggesting genuine equipment knowledge. The supplier's location in Inner Mongolia places it near major Chinese grain and seed production regions, which may inform its product focus. Buyers should independently verify company registration, manufacturing scope and quality management certifications before committing to purchase, as these are not disclosed in the available profile. Direct communication with the supplier is essential to assess production capacity, customisation options and after-sales support structures.
