About Shanghai Woshan Heavy Industry Machinery Manufacturing Co., Ltd. - Stone Crushers Supplier in China

Shanghai Woshan Heavy Industry Machinery Manufacturing Co., Ltd. is located in Shanghai, China and currently lists five active products. The catalogue comprises a Raymond mill, an energy‑saving ball mill, a high pressure micro‑powder grinder, an Mtm trapezium mineral powder grinder mill and a high pressure suspension mill. These machines fall under the broader categories of stone crushers, agriculture, drilling machines & tools, and light & medium machinery as indicated in the supplier’s top categories. Each product is classified within the HS‑code families for grinding and crushing equipment, typically under chapter 84 (machinery) and chapter 85 (electrical machinery). The supplier’s focus on high‑pressure grinding solutions reflects a niche within China’s heavy‑industry machinery sector.

The five listed products target customers who need fine‑particle production for minerals, chemicals, or agricultural processing. The Raymond mill is a classic vertical roller mill used for raw material grinding, while the energy‑saving ball mill offers reduced power consumption for medium‑scale operations. The high pressure micro‑powder grinder and suspension mill are designed for ultra‑fine powders below 50 µm, often required in pigment or ceramic industries. The Mtm trapezium grinder provides a specific geometry for consistent particle size distribution. All machines are built for continuous operation and can be integrated into production lines that handle capacities ranging from 1 t/h to 30 t/h depending on configuration.

Product Range and Specialties of Shanghai Woshan Heavy Industry Machinery Manufacturing Co., Ltd.

The supplier’s catalogue lists five grinding machines, each employing different milling principles: vertical roller (Raymond), ball milling, high‑pressure jet grinding, and a specialized trapezium‑type grinder. In the grinding equipment market, typical specifications include motor power from 75 kW to 300 kW, grinding media size from 10 mm to 50 mm, and achievable product fineness measured by d90 values of 10 µm to 100 µm. Buyers often request ISO‑standardized performance data such as throughput (t/h), specific energy consumption (kWh/t), and moisture tolerance. For high‑pressure mills, common pressure levels range from 5 MPa to 30 MPa, with particle size reduction to sub‑micron levels using jet impingement technology. The Raymond mill usually operates with a grinding pressure of 1 - 2 MPa and can handle feed sizes up to 50 mm. These grades and parameters align with standard industry expectations for mineral processing, cement grinding, and fine chemical production.

Trade and Export Information - Shanghai Woshan Heavy Industry Machinery Manufacturing Co., Ltd.

China is a major exporter of grinding and crushing machinery, with HS‑code 8479 covering other machines for crushing, grinding and polishing, and HS‑code 8479.89 for specialized grinding equipment. Typical import destinations for Chinese grinding mills include Southeast Asia, the Middle East, Africa and parts of Europe, where construction, mining and fertilizer sectors drive demand. Buyers generally require compliance with CE marking for the European market, ISO 9001 quality management certification, and, where applicable, IEC safety standards for electrical components. Export shipments are frequently arranged on 20‑ft or 40‑ft containers with machines crated on wooden pallets and protected by anti‑corrosion coating; larger units may be shipped as break‑bulk on roll‑on/roll‑off vessels. Common Incoterms for these heavy machines are FOB Shanghai or CIF major ports such as Rotterdam, Dubai or Lagos, reflecting the logistical norms for bulky industrial equipment.

Sourcing from Shanghai Woshan Heavy Industry Machinery Manufacturing Co., Ltd. - Buyer Guidance

When evaluating a quotation from this supplier, request a detailed data sheet that includes motor power, grinding capacity, expected product fineness (d90), and power consumption per tonne. Ask for a recent factory acceptance test (FAT) report and, if possible, a third‑party inspection certificate confirming compliance with ISO 9001 or CE standards. Verify the dimensions and weight of each unit to ensure compatibility with your plant layout and handling equipment; many buyers also request a 3‑D CAD model for installation planning. Samples of milled product are not typical for machinery, but a short trial run on a pilot line can demonstrate performance against your specification. Confirm the warranty period, spare‑parts availability, and the lead time, which for Chinese heavy‑industry equipment usually ranges from 30 to 90 days after order confirmation.

What types of grinding machines does Shanghai Woshan list in its catalogue?

The catalogue includes a Raymond vertical roller mill, an energy‑saving ball mill, a high pressure micro‑powder grinder, an Mtm trapezium mineral powder grinder mill and a high pressure suspension mill.

Which HS‑code families cover the machines offered by this supplier?

The machines fall under HS‑code 8479 (other machines for crushing, grinding and polishing) and related sub‑headings such as 8479.89 for specialized grinding equipment.

What performance specifications should a buyer request for the high pressure grinders?

Buyers should ask for rated pressure (typically 5 - 30 MPa), motor power (75 - 300 kW), throughput (t/h), and achievable particle size (d90 µm) as part of the technical data sheet.

Are any certifications required to import these machines into Europe?

Importers usually require CE marking and evidence of compliance with relevant IEC safety standards; a copy of the supplier’s ISO 9001 certificate is also commonly requested.

What is the typical lead time for orders from this Shanghai‑based supplier?

Lead times for the listed grinding equipment generally range from 30 to 90 days after order confirmation, depending on model complexity and any customizations.

How are the machines packaged for overseas shipment?

Machines are crated on wooden pallets, wrapped with protective film, and loaded into 20‑ft or 40‑ft containers; larger units may be shipped as break‑bulk cargo on roll‑on/roll‑off vessels.

What documentation should a buyer obtain before finalizing a purchase?

Request a detailed technical data sheet, a factory acceptance test report, ISO 9001 or CE compliance certificates, and a packing list indicating container dimensions and weight.

Can the supplier provide sample runs to verify product fineness?

While full‑scale sample runs are uncommon, the supplier can arrange a pilot‑scale test on site or provide data from previous installations to demonstrate achievable fineness levels.
