AI-Powered supplier vetting

SummaryYantai Huize Mining Engineering Co., Ltd. (HZE) is identified as a China-based manufacturer/factory and limited company specializing in mineral-processing and mining equipment. The supplier reports ISO 9000, ISO 9001, ISO 14000, and ISO 14001 certifications, 21–30 quality-control staff, more than 10 production lines, and 41–50 years of total R&D-engineer experience. Reported production includes 58 complete mineral-processing plants, 162 ball mills, 360 flotation machines, 188 jaw crushers, and 196 gold-leaching tanks. The company states it has self-operated import/export rights and that exports represent 51%–70% of sales. Evidence is insufficient to verify after-sales service, customization capability, or broad customer-case experience. Trade records show one transaction each associated with Tanzania and RAMANI INVESTMENT LIMITED for sleeves and springs, but these records do not establish performance or project success.

Supplier typeThe supplier is described as a Manufacturer/Factory and a limited company headquartered in Yantai, Shandong, China. Its stated offerings cover a broad range of mineral-processing equipment, although one associated-company classification identifies a trading-company nature, creating some classification inconsistency.

CertificationsThe supplier reports ISO 9000, ISO 9001, ISO 14000, and ISO 14001 management-system certifications. These stated certifications support the presence of formal quality and environmental management systems.

R&D capabilityThe supplier reports 41–50 years of total R&D-engineer experience and describes a company philosophy focused on detail and quality improvement. This supports an established technical development function, but no specific patents, proprietary technologies, or documented innovations are provided.

Production capacityThe supplier reports more than 10 production lines, 21–30 quality-control staff, and substantial output figures: 58 complete mineral-processing plants, 162 ball mills, 360 flotation machines, 188 jaw crushers, and 196 gold-leaching tanks. These figures explicitly support significant production capacity.

Product Q&A

Q:What is the working principle of this ball mill?

The transmission drives the cylinder to rotate. Materials and water are fed in, ground by steel balls into fine particles, and discharged via a grate device to prevent over-grinding.

Q:What are the main advantages of this grate ball mill?

It offers higher capacity than overflow mills, uses energy-saving bearings (20-30% savings), and features durable high manganese steel or rubber liners.

Q:Can the motor voltage be customized?

Yes, depending on customer site conditions, high-voltage or low-voltage electric motors can be selected.

Q:What types of materials can this machine process?

It is widely used for metal ores like gold, silver, copper, lead, zinc, nickel, iron, and non-metallic ores like limestone, barite, and quartz.

Q:What is the typical application scope?

It is generally used for primary grinding in mineral processing plants, with a product size of -200 mesh less than 70%.
