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 powder fineness?

The product fineness (D97=3-35um) can be adjusted at any time to produce variable mesh numbers from 1500 to 3500 mesh.

Q:What materials can this machine process?

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

Q:What is the maximum feed size and moisture content?

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

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 for this machine?

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