How does the grate discharge improve performance?

The grate type discharging device compels the slurry outside the cylinder, avoiding over-grinding faults and allowing for more capacity and bigger particle-size products.

Are there options for liner materials?

Yes, the liner materials can be chosen as high manganese steel or wear-resistant rubber depending on specific requirements.

What maintenance features are included?

The mill uses rolling bearings for easy maintenance, and big diameter models include an inching driving device. Hydraulic jacks are recommended for cylinder lifting.

Key features

High Capacity Grate Discharge: Grate type discharging device prevents over-grinding and increases capacity compared to overflow ball mills.

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

Durable High Manganese Liners: Grooved ring high manganese steel liners increase contact surface, strengthen grinding, and reduce energy consumption.

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

Modular Steel Frame Design: Steel frame allows modular plant design for mills up to 2.7m diameter, reducing civil construction and installation time.

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

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

Hydraulic Jack Option: Hydraulic jacks recommended for hybrid bearing mills to easily lift the cylinder for installation and service.

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 via the grate device to prevent over-grinding.

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

It features energy-saving bearings (20-30% savings), durable high manganese steel liners, large discharging outlets for higher capacity, and customizable motor voltages.

Q:What materials can be processed by this machine?

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

Q:Is the motor voltage customizable?

Yes, depending on the customer's site conditions and demands, the electric motor can be selected as either a high-voltage or low-voltage type.

Q:What is the typical application scope?

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.
