Key features

High Energy Efficiency: Rolling bearings and optimized liners save 20-30% energy compared to overflow ball mills.

High Capacity Output: Grate discharge design prevents over-grinding and increases capacity for bigger particle products.

Modular Steel Frame: Steel frame design for mills under 2.7m diameter reduces civil construction and eases installation.

Customizable Components: Customers can freely choose motor brand, reducer, and liner materials (high manganese steel or rubber).

Versatile Application: Suitable for grinding gold, silver, copper, lead, zinc, nickel, and various non-metallic ores.

Easy Maintenance: Hydraulic jacks and inching devices facilitate cylinder lifting, starting, and routine maintenance.

Wide Power Range: Motor power options range from 18.5kW to 2300kW to match different scale processing plants.

Reliable Lubrication: Air forced grease atomizer ensures perfect lubrication of pinion and girth gear for smooth operation.

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 enter from the feeding end, where steel balls grind them into fine particles. The grate discharge device compels the slurry out, preventing over-grinding and increasing capacity.

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

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

Q:Can I customize the motor and liner materials?

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

Q:What are the main advantages over overflow ball mills?

Compared to same-size overflow ball mills, this grate ball mill achieves higher capacity and produces larger particle-size products while avoiding over-grinding faults.

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% fineness, suitable for small, medium, or large scale mineral processing plants.
