AI-Powered supplier vetting

SummaryHenan Zhengzhou Mining Machinery Co., Ltd. is a professional machinery supplier focused on cement, metallurgy, mining, chemical, and related processing equipment. It reports more than 50 years of history, a 35,347 m² manufacturing plant, inventory capability, quality assurance, and multiple management and product certifications. Its after-sales scope includes installation, training, repair, maintenance, and debugging, but it reports no overseas agents or branches, overseas warehouse, showroom, or offline trade-show participation. The supplier demonstrates R&D, new-product development, 3D design, ODM, OEM, and broad customization capabilities. However, no effective manufacturing contracts with related subcontractors and no available SDK are reported. Specific customer cases are not provided.

Supplier typeThe supplier is a professional manufacturer of industrial equipment, with products spanning cement, metallurgy, mining, chemical processing, and related machinery. Its listed equipment includes rotary kilns, ball mills, production lines, dryers, conveyors, filters, and beneficiation equipment, supporting classification as a specialized machinery manufacturer rather than a general trading supplier.

CertificationsThe supplier reports ISO 9001:2015 quality-management certification, ISO 14001 environmental-management certification, ISO 45001:2018 certification, and CE product certification. These explicitly reported certifications indicate established quality, environmental, occupational-safety, and product-compliance systems.

After-Sales capabilityThe supplier reports clear procedures and records for corrective and preventive actions and customer complaints, as well as professional installation teams and an after-sales service guarantee system. It lists overseas service offerings including installation, training, repair, maintenance, and debugging, but has no overseas agents or branches and reports zero countries with overseas services, indicating documented capability but limited demonstrated overseas coverage.

R&D capabilityThe supplier identifies itself as a professional technical supplier, offers 3D software design, reports new products during the past year, and provides ODM and OEM services. The absence of an available SDK is a limitation for software-development integration, but the evidence supports product and engineering innovation capability.

Production capacityThe supplier reports quality assurance, in-stock capability, a 35,347 m² manufacturing plant, and a broad industrial equipment portfolio. However, it also states that neither the factory nor related subcontractors have valid manufacturing contracts, which creates a documented production-governance deficiency despite the reported facilities and inventory capability.

Customization capabilityThe supplier offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its reported 3D design, ODM, and OEM capabilities further support the ability to develop and manufacture tailored equipment or products.

Product Q&A

Q:What is the working principle of the rotary cooler?

The cooler rotates at low speed with a 3.5%-5% slope. Material enters from the high end, is lifted and scattered by plates, and cools as it moves down. Cold air is blown in, absorbing heat to preheat the kiln, while cooled material exits from the low end.

Q:What industries can use this rotary cooler?

It is widely used in building materials, chemistry, metallurgy, and mining industries, particularly as associated equipment for rotary kiln production systems.

Q:How efficient is the heat recovery process?

The heating efficiency can reach up to 95%. Waste gases from cooling are reused as secondary air in the kiln or as a heat source for drying coal, significantly decreasing overall heat consumption.

Q:What is the warranty period and after-sales service?

The warranty period is 12 months. We offer after-sale service including spare parts supply and installation guidance under our engineer's supervision.

Q:Is the product customizable?

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