AI-Powered supplier vetting

SummaryThe supplier is a China-based limited company focused on mining and grinding machinery, including vertical and ultrafine mills. It has 157 employees, one production line, experienced R&D personnel, machining equipment, and broad customization capabilities. Quality controls include 100% finished-product inspection and documented complaint-handling records, although some supplier-service procedures lack written records. The company states that it provides technical support and after-sales service and has OEM experience for popular brands. Production-support limitations include no in-stock capacity, overseas warehouse, overseas showroom, or valid manufacturing-capacity contract with related subcontractors. No certification information, customer cases, or verified financial strength is provided.

Supplier typeThe supplier is a limited company with combined business activities covering mining machinery, construction machinery, special equipment, metal structures, industrial automation, and graphite/carbon products. Its offered products are concentrated in grinding and vertical mill equipment, and it is not identified as part of a larger company group.

After-Sales capabilityThe supplier states that it provides technical support and professional after-sales services, and it has a clear customer-complaint procedure with follow-up records. However, it lacks in-stock service capacity, overseas warehouse capability, and overseas showroom capability, while some service-capability corrective-action procedures have no written records.

R&D capabilityThe supplier reports experienced management, advanced powder-equipment manufacturing technology, multiple R&D teams led by senior engineers, continuous technology improvement, and 29 years of total R&D-engineer experience. It does not provide SDK availability, but SDK capability is not necessary to establish machinery-development capability.

Production capacityThe supplier operates one production line and has dedicated manufacturing and machining equipment, including CNC, vertical lathe, drilling, boring, milling, and wire-cutting machines. Quality control includes 100% finished-product inspection, but manufacturing controls show weaknesses: there is no ongoing batch quantity reconciliation, no outsourcing SOP, no valid manufacturing-capacity contract with related subcontractors, and no inventory capacity.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. Its stated design-service range directly supports a broad ability to adapt products to customer requirements.

Product Q&A

Q:What is the adjustable product fineness?

The product fineness (D97=3-35um) can be adjusted at any time according to customer demand.

Q:What materials can this machine process?

It is suitable for nonmetallic minerals such as calcium carbonate, calcite, Kaolin, clay, barite, talc, gypsum, limestone, and more with Mohs hardness less than 5.

Q:What are the feed requirements?

The machine can feed materials with less than 3% moisture and less than 10mm in feed size.

Q:Does the system produce dust?

No, the whole system works under negative pressure without dust spreading outwards, ensuring clean production.

Q:Is customization available?

Yes, we offer full customization, minor customization, and flexible customization from samples or designs.
