What is the working principle of the mill?

Materials are crushed, fed evenly, and ground between rollers and rings. Airflow carries fine powder to a classifier for separation, while coarse powder returns for re-grinding. The system operates under negative pressure.

What are the payment terms?

Payment terms include LC, T/T, D/P, Western Union, and PayPal.

What is the average lead time for delivery?

The average lead time is within 15 workdays during both peak and off-peak seasons.

AI-Powered supplier vetting

SummaryZhengzhou General Mining Machinery Co., Ltd. is a mining and industrial equipment manufacturer producing TYM-brand crushing, milling, and related machinery. It reports ISO 9001 and QC 080000 certifications, more than 10 production lines, 6–10 R&D engineers, and 6–10 quality-control staff. The supplier supports customization, ODM, and OEM services, and reports new-product development during the past year. Its service system includes written procedures for supplier assessment, corrective actions, complaint handling, quality records, installation, training, repair, maintenance, and debugging in South Korea, Thailand, and Saudi Arabia. Production and export coverage appear broad, while overseas warehouses, showrooms, agents, branches, and offline trade-show participation are explicitly absent. Financial information is insufficient for a substantive credibility assessment because the supplied entries identify years but do not provide usable financial performance details.

Supplier typeThe supplier is presented as a manufacturer of its own TYM-brand mining machinery, serving mining, metallurgy, construction, chemical, and related industrial sectors. Its listed products include crushers, sand-making equipment, production lines, and mills, while its primary export markets span multiple global regions.

CertificationsThe supplier reports ISO 9001 and QC 080000 certification, and separately identifies an ISO 9001:2015 certificate within its sustainable-development management information. These entries provide explicit evidence of relevant management-system certifications.

After-Sales capabilityAfter-sales capability is supported by documented complaint-handling, corrective-action, supplier-assessment, and quality-record procedures. The supplier also lists installation, training, repair, maintenance, and debugging services in South Korea, Thailand, and Saudi Arabia, although it has no overseas warehouses, showrooms, agents, or branches according to the provided data.

R&D capabilityThe supplier reports new products during the past year, ODM capability, and 6–10 years of total R&D-engineer experience. Its company description also attributes its machinery to in-house design and innovation, but the absence of an available SDK limits evidence for software or integration-oriented innovation.

Production capacityThe supplier reports more than 10 production lines, 6–10 quality-control staff, quality assurance, raw-material traceability, and uniformly maintained quality instructions. These data explicitly support substantial production infrastructure and established quality-control practices.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full and flexible customization, and minor customization. It also reports ODM services and OEM services for well-known brands, demonstrating broad customization and contract-manufacturing coverage.
