What are the payment terms and lead time?

Payment terms include LC and T/T. The average lead time is one month during the off-season and 1-3 months during the peak season.

How does the grinding process work?

Materials are crushed, fed into the grinding chamber, and ground by rollers against the ring. The powder is then separated by an analysis machine, with qualified powder collected and coarse material regrinded.

What information is needed to get a quotation?

Please provide the raw material type, required hourly capacity, raw material input size, and the desired finished powder size for an accurate quotation.

AI-Powered supplier vetting

SummaryThe supplier is identified as a Chinese manufacturer/factory and limited company, with a stated product range covering anemometers, thermometers, air compressors, stone crushers, ball mills, and rotary dryers. It reports ISO 20000 certification, 11–20 R&D engineers, 11–20 quality-control staff, one-month lead times in both peak and off-peak seasons, and export activity across multiple regions. OEM service for popular brands and several customization methods are indicated. However, the supplier reports no available SDK, no written corrective-action or complaint-handling procedures, no raw-material traceability, no overseas service infrastructure, and no offline trade-show participation. The provided financial entries identify years but do not provide financial performance values, so financial credibility cannot be determined. Customer cases are not explicitly documented.

CertificationsThe supplier reports certification of its management systems under ISO 20000. The provided information does not identify the certification scope, validity, issuing body, or additional product and quality certifications, so the significance for the intended supply requirements cannot be fully assessed.

After-Sales capabilityThe supplier has quality assurance, but reports no written procedures or records for corrective and preventive actions, customer complaint handling, or supplier-service assessment. It also has no overseas showroom, agents or branches, and reports zero countries with overseas services, indicating limited documented and international after-sales infrastructure.

Production capacityThe supplier is identified as a manufacturer/factory, reports 11–20 quality-control staff, one-month lead times in peak and off-peak seasons, and self-operated import/export rights.
