What quality control measures are taken before shipment?

All drums undergo static balance tests to achieve G40 accuracy. Additionally, circumferential and longitudinal welds undergo non-destructive testing, and hubs undergo magnetic particle or ultrasonic testing.

What is the lead time for production?

The average lead time is 1-3 months during peak season and one month during the off-season.

AI-Powered supplier vetting

SummaryShandong Mining Machinery Group Co., Ltd. is identified as both a trading company and manufacturer/factory based in Shandong, China. The supplier reports a long operating history since 1955, 21 holding subsidiaries, more than 10 production lines, stated production capacities across conveyor and mining-equipment categories, and export activity since 2013 with self-managed import/export rights. It reports QHSE, ISO 14001, ISO 9001, and HSE certifications, as well as 50 R&D engineers and 50 quality-control staff. Its service network includes 26 parts warehouses nationwide. Evidence supports substantial manufacturing, quality-system, service-network, and engineering capabilities. However, the provided slices do not establish specific customer projects or directly verify financial strength; the registered-capital figure is therefore not considered in accordance with the privacy requirement.

Supplier typeThe supplier is explicitly classified as both a trading company and manufacturer/factory. Its stated business covers industrial equipment and processing machinery, while its products include belt conveyors, scraper conveyors, hydraulic supports, crushers, reducers, and related components.

CertificationsThe supplier reports QHSE, ISO 14001, ISO 9001, and HSE management-system certifications. These explicitly indicate coverage of quality, environmental, health, safety, and broader QHSE management requirements.

After-Sales capabilityThe supplier states that it has established 26 large-scale parts warehouses nationwide, forming a marketing and service network. It also reports EPC, BOT, and BT operation-and-maintenance capabilities for bulk-material conveying projects, supporting a substantial service and project-support structure.

R&D capabilityThe supplier describes innovation as part of its business philosophy and reports an intelligent IoT cloud platform and intelligent control-system software. It also reports 50 R&D engineers, providing explicit evidence of dedicated technical-development resources.

Production capacityThe supplier reports more than 10 production lines and stated output of 5,000 hydraulic-support sets, 500 belt-conveyor sets, 2,000 scraper-conveyor sets, 200,000 conveyor pulleys, and 1,000,000 conveyor rollers. These figures demonstrate broad and sizeable production capacity across major product categories.

Product Q&A

Q:What is the maximum pulley diameter and tension capacity?

We can produce conveyor pulleys with a diameter up to 1.8 meters and a maximum tension capacity of up to 300 tons.

Q:What surface types are available for the pulleys?

Available surface types include smooth, rubber lagging, and ceramic rubber lagging. Adhesive treatments like coal bonding or hot vulcanization are also supported.

Q:Can the color of the pulley be customized?

Yes, the color of the pulley is customized to meet your specific requirements.

Q:What materials are used for the pulley pipe and shaft?

The pulley pipe is made of Q235B carbon steel with high roundness and straightness. The shaft is made of 45# round steel or according to your requirements, with strict tolerance control.

Q:How is the connection between the shaft and wheel handled for heavy-duty pulleys?

For medium and heavy-duty pulleys, the shafts and wheels are connected by expansion sleeves, which solves stress concentration problems and ensures overall quenching.
