Discover a premium used 9ft × 14.8ft ball mill manufactured in 2017 by Luoyang Zhongshi Group—a trusted name in Chinese mining equipment engineering. Originally deployed at a large-scale building materials group in Linyi, Shandong Province, this core grinding solution is engineered for continuous, high-efficiency operation across mining, metallurgy, building materials, and chemical industries.

Fully refurbished to industry standards, all critical wearing parts have been replaced with new original-specification components: new cylinder liners, main bearings, shaft bushes, high-performance seals, premium lubrication fluids & filters, and transmission accessories. This thorough upgrade restores the mill to near-new performance, eliminating wear-related inefficiencies and ensuring reliable, factory-level operation.

The mill features a robust, deformation-free main structure with maintained original factory roundness, tight flange/end cover connections, and fully functional motor/control systems with sensitive start-stop controls. Only minor surface rust and old paint (normal wear traces) remain, easily removable with basic cleaning and repainting for a polished appearance. With a processing capacity of 45–65 tons per hour and adjustable fineness (200–325 mesh), it supports both dry/wet grinding for ores, cement clinker, quartz sand, and more.

 As a cost-effective alternative to new equipment (priced at 40–50% of new), this Luoyang Zhongshi ball mill delivers unmatched value with full production readiness. We offer strict pre-sale inspection, global transportation, on-site installation, operator training, and warranty coverage for new parts. Welcome to arrange on-site testing and request detailed specs, photos, and competitive quotes—your trusted partner for used mining equipment solutions.

As a classic and reliable model of Luoyang Zhongshi Group, this ball mill is designed for long-term continuous production. It features stable structure, high transmission efficiency, and supports both dry and wet grinding processes. With a processing capacity of 45–65 tons per hour, the grinding fineness can be flexibly adjusted between 200 and 325 mesh according to production requirements, which can stably meet the fine grinding demands of various materials.

Our professional team has completed full maintenance and replaced all wearing parts with new original-standard parts:

All cylinder liners are replaced with new original-specification liners, restoring grinding efficiency to factory level;Main bearings and bearing bushes are replaced with new original matching parts, ensuring stable operation and qualified assembly accuracy;Sealing components at the feed and discharge ends are all replaced with new original parts, providing reliable sealing and completely preventing material leakage and oil seepage;The lubrication system has been thoroughly cleaned and maintained, with new original-standard lubricating oil and filter elements replaced;Transmission belts, coupling buffers and other vulnerable parts are also replaced with new original parts synchronously.

The main structure of the equipment is solid, without deformation or cracks. The cylinder roundness is maintained to the original factory standard. The flanges and end covers are tightly connected. The motor and electrical control system are in good condition with neat wiring, sensitive start-stop and stable operation. Only slight old paint and minor surface rust exist on the appearance, which are normal traces of use. After simple rust removal, cleaning and painting, the machine will present an excellent look. The mill runs smoothly with low noise and vibration, and can be put into formal production immediately after basic installation and commissioning.

This Luoyang Zhongshi 9 ft × 14.8 ft ball mill has obvious advantages: large capacity, stable fineness control, easy maintenance and long service life. It is suitable for high-intensity and long-term continuous production. As a used machine with all key wearing parts renewed, its performance is close to a new one, while the purchase cost is much lower, providing extraordinary cost performance.
