AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier with 3D software design and broad customization capabilities. It reports advanced manufacturing equipment, five production lines, ISO 9000 certification, quality assurance, and raw-material traceability. Its stated technical scope includes wear-resistant materials project planning, process technology support, and operator and maintainer training. However, evidence also shows no in-stock service, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. After-sales and complaint-handling procedures are undocumented, warehouse quality-control processes were not found, and no quality-control testing equipment was reported. Financial information is inconsistent or insufficient for assessment: some records state zero operating figures, while another slice reports an annual production output range; monetary figures are excluded here.

Supplier typeThe supplier is explicitly described as a professional technical supplier and operates across special equipment, fasteners, plastics, mechanical equipment, metal products, and mechanical components. Its descriptions also identify technical manufacturing, project planning, process support, and equipment-related services.

CertificationsThe supplier reports holding ISO 9000 certification. This is explicit evidence of certification-system holding, although no further certification scope or validity details are provided.

R&D capabilityThe supplier reports strong research and development capability, independent development of casting-related production lines, 3D software design services, and project/process technology support. Conversely, only one R&D engineer is listed, with responsibilities focused on providing samples, and no SDK is available; the evidence supports technical development capability but not broad innovation strength.

Production capacityProduction evidence includes advanced manufacturing equipment, dedicated casting and heat-treatment equipment, five production lines, and reported quality-control staffing of 41–50. However, the site reported zero quality-control test equipment and no warehouse-control process found, so production scale is supported while production-quality infrastructure appears inadequately documented.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides project planning and design for new wear-resistant-material enterprises, directly supporting a broad customization capability.

Product Q&A

Q:Why high chrome grinding ball need quenching and tempering process?

When the high chromium ball is cast, the hardness is low, and the direct use is easy to wear. High chromium casting ball through high temperature quenching, forming high hardness martensitic structure, hardness from HRC 40+ to HRC 60+, wear resistance directly doubled. High chromium balls with different chromium content should be quenched in the corresponding way. There are three common quenching methods for high chromium casting balls, oil quenching, liquid quenching and wind quenching

Q:How does mining companies reduce the consumption of grinding balls?

1) Combined with the material properties and the conditions of the minings, choosing cost-effective, stable quality of high-quality steel balls for the minings. 2) Help users establish a regular clearance system for steel balls. Remove and discharge invalid steel balls in the mill in time. 3) Assist users to develop the steel ball plus ball system. Do science, add steel balls accurately. 4) Random sampling inspection of the particle size distribution of the materials.

Q:What should we pay attention to when adding steel balls to ball mills?

In the daily production process of the ball mill, the friction between the steel ball and the material and the liner will grind the large steel smaller. So normally, just add big balls. Unless the fineness of the ball mill does not meet the requirements, the appropriate amount of small balls can be added. Under normal circumstances, it is best to control the amount of steel ball loading in the conventional ball mill at about 40%-50%. The steel ball installed in the cylinder body is a little lowe
