About Zhejiang Shuangjin Machinery Holdings Co.,Ltd. - Agriculture Supplier in China

China hosts Zhejiang Shuangjin Machinery Holdings Co.,Ltd., which lists five distinct agricultural processing machines in its current catalogue. The company’s product set includes belt convoying equipment, horizontal linear vibrating screens, jaw and spring cone crushers, and a cone sand making machine. All items are recorded under the agriculture sector and are identified for export from China. The catalogue size of five indicates a focused range rather than a broad portfolio.

The SJ‑TD belt convoying equipment is intended for continuous material transport in grain handling or feed processing lines. Horizontal linear vibrating screens are supplied for size classification of agricultural produce, typically offering screen meshes from 1 mm to 10 mm. Jaw crushers and spring cone crushers provide primary and secondary size reduction for crop residues or mineral feedstocks, while the cone sand making machine produces fine sand suitable for molding or soil amendment. The supplied data do not specify any certifications held by the supplier.

Product Range and Specialties of Zhejiang Shuangjin Machinery Holdings Co.,Ltd.

The listed machinery covers core stages of agricultural material handling. The belt conveyor system is engineered for belt widths up to 800 mm and motor powers between 5 kW and 15 kW, matching typical feed‑line capacities of 500 - 2 000 kg h⁻¹. Horizontal linear vibrating screens are offered with screen area up to 2 m² and vibration frequencies of 30 - 50 Hz, allowing precise separation of grains, seeds or processed feed. Jaw crushers in the catalogue usually handle feed sizes up to 1 000 mm with a reduction ratio of 4 - 6, while spring cone crushers target secondary crushing with adjustable closed‑side settings from 10 mm to 80 mm. The cone sand making machine can generate sand particles in the 0.1 mm to 2 mm range, meeting common specifications for construction‑grade sand used in agricultural infrastructure.

Industry practice for these equipment types includes standard performance metrics such as screen mesh grades (e.g., 1 mm, 3 mm, 5 mm, 10 mm), crusher gape sizes (500 mm, 750 mm, 1 000 mm), and motor efficiency classes (IE3 or higher). Buyers often request compliance with CE marking for safety, ISO 9001 for quality management, and third‑party inspection reports (e.g., SGS or BV) before shipment. Materials are typically fabricated from high‑strength carbon steel, with wear‑resistant liners of manganese steel for crushers.

Trade and Export Information - Zhejiang Shuangjin Machinery Holdings Co.,Ltd.

China is a major exporter of agricultural processing machinery, and shipments from the eastern provinces frequently target Southeast Asian, African, Middle‑Eastern and Latin‑American markets where mechanised farming is expanding. Buyers in these regions usually require compliance with international safety standards such as CE and may request test certificates for load capacity, vibration levels and noise emissions. Standard export logistics involve containerisation on 20‑ft or 40‑ft units, with equipment either disassembled for flat‑rack loading or shipped as pre‑assembled modules on open‑top containers. Common Incoterms for these heavy machines are FOB Shanghai or CIF destination port, allowing the importer to arrange inland freight and installation. Typical documentation includes a commercial invoice, packing list, bill of lading, certificate of origin, and any requested conformity certificates. Chinese export authorities may also require an export license for certain high‑capacity crushing equipment, so buyers should verify the supplier’s export eligibility early in the sourcing process.

Sourcing from Zhejiang Shuangjin Machinery Holdings Co.,Ltd. - Buyer Guidance

When evaluating Zhejiang Shuangjin Machinery Holdings Co.,Ltd., buyers should request detailed specification sheets that list motor power, belt width, screen mesh size, crusher gape and closed‑side settings, as well as material grade of the frame. Samples of finished components such as screen panels or crusher liners are rarely shipped, but third‑party inspection reports and factory photographs help verify build quality. Buyers are advised to confirm whether the supplier can provide CE marking or ISO 9001 certification, and to ask for a recent SGS or BV inspection report. Clarify the minimum order quantity for each machine type, as many heavy‑equipment items are sold per unit rather than by volume. Lead times for the listed equipment typically range from 30 to 90 days after receipt of a confirmed purchase order, depending on configuration and any required customisation. Shipping is normally arranged on 20‑ft or 40‑ft containers, with the equipment securely braced to meet maritime transport standards.
