Import Gravity Destoner — Buy in Bulk from Supplier in China

The Gravity Destoner supplied by Hebei Helida Grain Selecting Machinery Technology Co., Ltd. is a grain cleaning machine that separates stones from harvested grain using density differences. It employs a multi‑blade fan to keep lighter grain in suspension while larger stones cling to a stainless‑steel mesh as air pressure is adjusted. The vibrating table’s frequency can be finely regulated by a frequency‑conversion control device, allowing separation even when density contrast is minimal. The system adjusts both pressure and vibration frequency to achieve consistent stone removal.

The mesh is fabricated from stainless steel, providing corrosion resistance suitable for humid storage environments. The fan blades are precision‑cut to maintain uniform airflow across the grain stream. In the grain processing sector, such destoners are typically rated for feed rates between 0.5 and 2 tonnes per hour and achieve stone removal efficiencies above 95 %. The equipment’s modular design permits integration with existing cleaning lines without extensive re‑layout.

Primary users include large‑scale grain aggregators, export terminals and feed‑mill operators who require reliable stone removal before storage or further processing. The machine can be shipped in a disassembled crate with standard container dimensions; buyers should confirm packaging details and incoterms with the supplier. As the supplier’s response rate is currently zero, importers are advised to request quotations and lead‑time confirmation directly. Payment and warranty conditions are not disclosed in the listing and must be negotiated with the supplier.

Hebei Helida Grain Selecting Machinery Technology Co., Ltd. is based in Shijiazhuang, Hebei Province, China, with its registered address in the Dongdu Zhuang Industry Area (postal code 050000). The company is listed with a harbor trust tier, indicating participation in the platform’s verification system, although its current response rate is 0 % and average response time is not recorded.

The supplier focuses on designing and manufacturing grain cleaning equipment, including destoners and separators, for domestic and export markets. Its product catalogue highlights the use of stainless‑steel components and adjustable control systems, but the listing does not provide details on production capacity or certifications. Prospective buyers should request additional documentation such as factory audit reports or quality certificates.
