Henan Hongke Heavy Machinery Co., Ltd. has shipped a Φ1.5×4.5m ball mill to a customer in India. The mill is configured for fine grinding of mineral raw material in a small-to-medium grinding circuit.
This article covers the full project: customer background, the original problem, equipment configuration, delivery timeline, factory testing results, and customer feedback.
1. Customer Background
Location: India
Industry: Mineral processing / grinding circuit
India’s mineral processing sector includes many small-to-medium grinding circuits serving regional markets—industrial minerals, ore dressing, and chemical raw materials. These operations often need compact, reliable mills that can be installed quickly and run with limited maintenance.
Our customer is a mineral processing operator in India. They needed a ball mill for fine grinding of their raw material, with a target output suitable for downstream processing. The selected model was Φ1.5×4.5m.
2. The Original Problem
Before approaching Henan Hongke Machinery, the customer faced several practical constraints:
| Problem | Impact |
|---|---|
| Existing mill too small or unreliable | Could not meet target fineness or throughput |
| Inconsistent product fineness | Downstream process efficiency affected |
| High maintenance frequency | Liners and bearings wore out quickly |
| Limited spare parts support | Long downtime waiting for parts |
| Installation footprint | Site space constrained equipment size |
| Budget control | Needed a cost-effective solution without sacrificing reliability |
The customer needed a compact ball mill—new equipment, configured for their material and site—with reliable after-sales support.
3. Why the Customer Chose Henan Hongke Machinery
After evaluating several suppliers, the customer selected us for specific, practical reasons:
a) Right-sized model for their circuit
Φ1.5×4.5m is a compact mill suited to small-to-medium grinding circuits. We confirmed the model against their target fineness and throughput before quotation—not just pushed the largest available unit.
b) Configuration matched to their material
We reviewed the customer’s feed material characteristics (particle size, hardness) and recommended liner profile and grinding media gradation accordingly.
c) Complete mill package, not just the shell
We supplied the mill shell, liners, grinding media, drive system (motor, reducer, girth gear), main bearings, lubrication system, and control panel—so the customer did not have to source components separately.
d) Factory testing before shipment
The mill was assembled and run at our facility before shipment, so mechanical issues were caught before the unit left China.
e) After-sales support commitment
The customer wanted a supplier available for installation guidance, spare parts, and technical advice after delivery.
