Key features

High Capacity Grate Discharge: Grate type discharging avoids over-grinding and achieves higher capacity than overflow ball mills.

Energy Saving Design: Large double row self-aligning rolling bearings reduce friction, saving 20-30% energy.

Customizable Motor Options: Electric motors can be selected as high-voltage or low-voltage types based on customer site conditions.

Durable Liner Materials: Grooved ring high manganese steel liners or wear-resistant rubber liners are available to increase grinding strength.

Modular Steel Frame: Steel frame design for mills up to 2.7 meters diameter facilitates modular plant installation and reduces civil construction.

Versatile Application Scope: Suitable for primary grinding of metal ores (gold, copper, etc.) and non-metallic materials like limestone and quartz.

Easy Maintenance Features: Hydraulic jacks for large mills, inching driving devices, and air forced grease spaying ensure smooth operation and service.

Wide Power Range: Motor power options range from 18.5kW to 2300kW to suit various production scales.

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 the Grate Ball Mill?

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

Q:What are the main advantages of this ball mill compared to overflow types?

It achieves higher capacity, obtains bigger particle-size products, and avoids over-grinding faults due to its grate type discharging device.

Q:Can the motor voltage and liner materials be customized?

Yes, depending on site conditions, you can choose high-voltage or low-voltage motors, and select between high manganese steel or wear-resistant rubber liners.

Q:What types of materials can this ball mill process?

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

Q:What is the typical application scope for this equipment?

It is generally used for primary grinding where the product size is -200 mesh with less than 70% passing rate, suitable for small, medium, or large scale mineral processing plants.
