Do you provide after-sales service overseas?

Yes. We offer lifetime technical support and spare parts supply. If needed, our engineers are available to travel overseas for installation guidance, commissioning, and operator training.

How is the machine packed and shipped?

Due to its large size, the machine is disassembled into several parts. The main cylinder is usually shipped in nude packaging (secured on a steel frame), while precision parts like the motor, reducer, and bearings are packed in standard export wooden cases.

What is the discharge size?

The standard discharge size ranges from 0.074 mm to 0.4 mm. This can be adjusted based on your specific grinding requirements.

Product Q&A

Q:What is the processing capacity of this ball mill?

The design capacity is 80 to 260 tons per hour (TPH). The exact output depends on the hardness of the raw ore and the required discharge fineness.

Q:What material is used for the liners? How long is the service life?

We use ZGMn13 High Manganese Steel liners. This material has excellent impact resistance and work-hardening properties, making it highly durable for grinding hard ores like gold and iron. The lifespan depends on your specific ore, but it is significantly longer than standard steel liners.

Q:What brand of bearings do you use?

We use Wafangdian bearings, which is the top-tier and most reputable bearing brand in China. This ensures the stable operation and long service life of the machine's core components.

Q:Does the price include grinding media (steel balls)?

No, the base price is for the main machine only. The 5.5 tons of steel balls are calculated separately. You can purchase them from us, or source them locally to save on freight.

Q:What is the warranty period?

We provide a 1-year warranty starting from the date of successful installation and commissioning.
